![]() In general, you measure the absorbance of a series of known concentrations of a standard protein to create a standard curve. Unlike the Folin-Lowry method, the Bradford assay doesn’t have a set endpoint, so you have to use this standard curve to calculate protein concentration based on its absorbance. It’s based on the interaction between Coomassie brilliant blue (you know, the stuff you stain your SDS-PAGE gels with) and the arginine and aromatic residues in your protein. When the dye binds to these residues, its maximum absorption shifts from 470 nm to 595 nm. There are good reasons that the paper first describing the Bradford Assay has been cited thousands of times! (2) The Bradford assay is an elegantly simple colorimetric assay for protein quantification. In which case, one of the following techniques might be more useful for you. This can be difficult to do especially if you freeze protein and use it for weeks/months but you no longer have the exact buffer to blank against. This doesn’t mean that UV-Vis is incompatible with DTT, it just means that you should use an exact DTT-containing buffer match to measure protein concentration more accurately. If you use DTT in your protein preps and use A 280 to measure protein concentration-be careful! DTT oxidizes over time leaving a product that also absorbs at 280 nm. Alcohols, certain buffer ions, and nucleic acids all absorb at 280 nm, thereby making this measurement non-specific for protein if any of these other molecules are present. To make matters worse, lots of other molecules interfere with this method of protein quantification. These factors alone make this approach unreliable. (1) Disadvantages of Measuring Protein Concentration using Absorbance at 280 nmĮvery protein has a different number of tyrosine and tryptophan residues and, annoyingly, you may not know the experimental extinction of your protein. If you’re working with purified protein samples and if you measure the complete UV-vis spectrum of your protein sample rather than just the A 280, you can also see if there are any soluble aggregates in your sample by looking for absorbance at 230 nm. This is a quick method and doesn’t require any special reagents, except for the guanidinium, which you may have on hand anyway. Advantages of Measuring Protein Concentration using Absorbance at 280 nm Once you know the absorbance of your protein at 280 nm (A 280), as well as its extinction coefficient, you can use the Beer–Lambert law to calculate protein concentration:Ĭ = molar concentration of protein. Simple but often unreliable, this protein quantification method estimates the amount of protein by measuring the characteristic absorption of the aromatic residues, tyrosine, and tryptophan, at 280 nm on a UV-Vis spectrometer. It can be difficult to decide on the best method for your protein, especially considering that even the most humble protein quantification assay uses some pretty sophisticated chemistry that can trip you up (particularly if you’re working with detergents!). There are several ways to measure protein concentration, and each of them has its own advantages and disadvantages. Even if you’re doing something more qualitative, having a good idea of how much protein you have will enable you to compare results from one experiment to the next and from one protein to the next. Why is Accurate Protein Quantification Important?Īccurate protein quantification is critical if, for example, you’re trying to determine a binding constant, measure enzyme kinetics, or if you’re preparing samples for a western blot. ![]() In this article, we’re going to discuss five major protein quantification techniques-how they work, when they work, and when they don’twork. But there are so many methods out there, how do you know which one is right for you? Accurate protein quantification is key when working with proteins. Describe the pattern observed in the multiples of these numbers. This pattern is just a variation of the pattern we observed in the diagonals of the table.Įxample 2: Compare the rows of 3 and 6. The commutative property states that 7 \( \times \) 3 = 3 \( \times \) 7 = 21. The number 21 in the highlighted column is obtained by multiplying 7 \( \times \) 3, and the 21 in the highlighted row is obtained by multiplying 3 \( \times \) 7. Consider the number 21 in the highlighted row and the highlighted column. The property which creates this pattern can be identified by observing the numbers in the highlighted row and column. Describe the property that creates this pattern. The same trend is observed among all the numbers in all diagonals.Įxample 1: The highlighted row and column of the multiplication table have the same set of numbers. On its left side, 15 is obtained by multiplying 5 \( \times \) 3, and on its right side, 15 is obtained by multiplying 3 \( \times \) 5, giving the same result. 16 is obtained by multiplying 4 by itself. Consider the diagonal with the numbers 7, 12, 15, 16, 15, 12, and 7. The numbers in the diagonals repeat themselves in the reverse order because of the factors. This applies to the multiplication of all numbers. The commutative property of multiplication states that when we multiply numbers in any order, we will get the same result.įor example, 2 \( \times \) 3 = 6 and 3 \( \times \) 2 = 6, 5 \( \times \) 8 = 40 and 8 \( \times \) 5 = 40. This pattern is created due to the commutative property of multiplication. The same pattern can be observed in the second and the third highlighted diagonals. The products following this number are the same as the ones that appeared before it. When we reach the middle of the first diagonal, we have 4 \( \times \) 4 = 16. One of the highlighted diagonals has the numbers 7, 12, 15, 16, 15, 12, and 7. Look for a pattern among the highlighted numbers in the diagonals. The same property can be observed for all columns where the sum of values in any two columns is equal to the value of another column for a given row. In math terms, if c = a + b, then 5 \( \times \) c = 5 \( \times \) (a + b) = 5 \( \times \) a + 5 \( \times \) b. ![]() The property states that multiplying the sum of two or more addends by a number is the same as multiplying each addend separately by the number and then adding the products together. This pattern is created due to the distributive property of multiplication. ![]() Similarly, 27 + 45 = 72, where 27, 45, and 72 are multiples of 3, 5, and 8 that we get by multiplying them with 9. For example, 15, 25, and 40 are multiples of 3, 5, and 8 that we get when we multiply these numbers by 5. That is, the multiples of 8 are the sum of multiples of 3 and 5 for a given factor. An interesting fact here is that the multiples of these numbers follow the same rule. ![]() ![]() Consider the columns for 3, 5, and 8 and compare the products in these columns. We can observe an interesting pattern in the multiplication table by looking at its columns. It consists of three values - the radial distance, the polar angle, and the azimuthal angle. It measures the angle from the origin to a point on a sphere in three dimensions. Spherical coordinates are a system of coordinates used to specify positions or locations on a sphere. Spherical coordinates are used in a variety of applications, including navigation, physics, astronomy, and engineering. The length is the distance, or radius, r. The angles are the polar angle, ?, the azimuthal angle, f, and the radial angle, ?. This system uses three angles and one length to precisely locate any point in space. Spherical coordinates are a useful tool for representing points in 3D space. So, the spherical coordinates of the point (3, -4, 5) are (7.07, -53.13�, 45�).Ĭalculate the spherical coordinates of the point (-3, 4, 5): So, the spherical coordinates of the point (2, 3, 5) are (6.16, 56.31�, 54.74�).Ĭalculate the spherical coordinates of the point (3, -4, 5): Let's practice calculating spherical coordinates with a few more examples.Ĭalculate the spherical coordinates of the point (2, 3, 5): ![]() First, we'll calculate the radius:įinally, we'll calculate the azimuthal angle: To do this, we'll use the equations we learned earlier. In the first example, we'll calculate the spherical coordinates of the point (3, 4, 5). To better understand spherical coordinates, let's look at a few examples. This makes it possible to calculate the surface area and volume of different 3D shapes. By using the three angles and the radius, a point in space can be precisely located. In addition to these applications, spherical coordinates can also be used to solve problems involving 3D shapes, such as cylinders, cones, and spheres. Spherical coordinates are also used in astronomy to describe the position of stars relative to Earth. One of the most common applications of this system is in spherical trigonometry, which is used to calculate distances, angles, and areas on the surface of a sphere. The values of x, y, and z can be calculated from the polar, azimuthal, and radial angles using the following equations: The equations for calculating spherical coordinates are as follows: The spherical coordinate system uses three angles and one length to locate any point in space. The radial axis is the line that passes through the origin and is perpendicular to the plane of the two other axes. The azimuthal axis lies in the plane of the two other axes and passes through the origin. The polar axis is a line that passes through the origin and is perpendicular to the plane of the two other axes. Together, these three axes form the spherical coordinate system. ![]() These three axes are known as the polar, azimuthal, and radial axes. Instead of two axes, spherical coordinates use three axes to represent a 3D point in space.

"A picture is worth a thousand words," this quote conveys the message of using a genogram. This can not be achieved by blatantly stating: “He is sad”. Of course, you can blatantly state the emotions of your character, but how convincing is this? You want your readers to get drawn into your story, to understand what your character feels, to be invested in what is going on. Instead of a pure list, the wheel gives a practical, color-coded overview that is easier to remember and helps to quickly distinguish the emotion you are looking for. On the other hand, it helps to contrast characters with different characterizing emotions as well as setting up scenes and roles by choosing contrasting feelings for protagonist and antagonist, hero and villain. On one hand, it gives a neat, short overview of the eight “basic” and eight “derivative” emotions of the human being. Looking at the Wheel of emotions from a writer’s perspective can help to fine-grain emotions you want to portray in your writing. If you are interested in the psychology and theory behind this, we encourage you to read Plutchik’s paper The Nature of Emotions. While the contrast between joy and sadness seems obvious, would you have thought that the opposite of fear would be anger? By Machine Elf 1735 (Own work), via Wikimedia CommonsĪs we can see, this wheel contrasts the most well-known emotions in a sometimes comprehensible, but sometimes also surprising way.
