So, how does SDS-PAGE work in determining the size or molecular weight of unknown proteins? Here's everything you need to know.

We are committed to sustainability and reducing single-use plastic, and our range of water filters, drinking water solutions and water softeners are designed to eliminate the need for plastic water bottles and plastic waste as well as being good for the environment.

The sample buffer should also contain SDS. SDS binds to hydrophobic protein regions to denature secondary, tertiary and quaternary structures and give a net negative charge on the proteins. SDS causes proteins to unfold to random, rod-like chains without breaking any covalent bonds in the process. This causes proteins to lose their biological functions without damaging their primary structures.

After running the gel, you should then determine the relative migration distance (Rf) of the protein standards and the unknown protein. The migration distance can be determined using the following equation:

It uses the same unique twin cylinder design as the HarveyArc water softener which allows for both cleaning & softening simultaneously, ensuring that your home enjoys an uninterrupted supply of softened water.

Multiple data points should be generated to make sure that the data carries a statistical significance. For best results, try using at least three gels.

In solubilizing the proteins, the sample buffer should contain reducing agents such as dithiothreitol or B-mercaptoethanol to ensure that the disulfide bonds will be broken. As you may already know, disulfide bonds reduce the effect of secondary structure on migration.

So for the example pictured, the unknown protein has an Rf of 0.7084. Using the equation for the linear plot we can calculate the Log (MW). (-2.0742 x 0.7084) +2.8 = 1.3305.  So the inverse log is 10^1.3305= 21.4kDa for the molecular weight of the unknown protein.

How can you estimate the molecular weight of an unknown protein? Well, you can do it by using the SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis) method. Although there are some other methods (i.e. analytical ultracentrifugation and light scattering) for calculating the size or molecular weight (MW) of an unknown protein, they are not commonly used for this purpose since they use large amounts of highly purified proteins and require costly equipment.

To determine the molecular weight of an unknown protein, you should separate the sample on the same gel with a set of molecular weight standards. After running the standards and the unknown protein sample, the gel is processed with the desired stain and then de-stained for about 12 to 14 hours to visualize the protein bands.

Based on the values obtained for the bands in the standard, the logarithm of the molecular weight of an SDS-denatured polypeptide and its relative migration distance (Rf) is plotted into a graph. Please take note that you will generate a linear plot for most proteins if your samples are fully denatured and the gel percentage is appropriate for the molecular weight range of the sample. If you get a sigmoidal curve, it means that the sieving effect of your matrix is either too large that it restricts the penetration of the molecules into the gel or is nearly negligible that it allows protein molecules to migrate almost at their free mobility.

Note: You can use a ruler to measure the migration distance (in centimeters) from the top of the gel to every major band in the gel. Alternatively, an appropriate software may also be used to determine the Rf values of the resulting bands.

Keep in mind that the unknown protein should be within the linear range of the standard curve to allow for the accurate determination of its molecular weight. In addition, the amount of the unknown protein should match the corresponding standard to increase the accuracy of the results.

Given its importance in determining the molecular weight of an unknown protein sample, you need to select the appropriate separation conditions when doing your experiment. To do this, you need to take the following factors into consideration:

An improved Coomassie Dye based protein assay based on the Bradford Protein Assay. This assay is suitable for the simple and rapid estimation of protein concentration. This assay is based on a single Coomassie dye based reagent. The binding of protein to the dye results in a change of color from brown to blue. The change in color density is proportional to protein concentration. Protein estimation can be performed using as little as 0.5µg protein.

Interpolating the value from this graph will then give you the molecular weight of the unknown protein band. Please note that the accuracy of this method in determining the molecular weight of an unknown protein typically ranges from 5% to 10%. The presence of polypeptides such as glycol- and lipoproteins usually leads to erroneous results since they are not fully coated with SDS and thus, would not behave as expected.
