Gel electophoresis is laboratory technique which is used to seperate mixtures of RNA, DNA and proteins. Gel electophoresis involves an electric field, Since RNA and DNA are negatively charged molecules they migrate towards positive end of the gel and get seperated. But proteins are not negatively charged so they must first mix proteins with a detergent called sodium dodecyl sulfate. This makes the proteins unfold into linear shape and coats with a negative charge, which allows them to migrate towards positive end of the gel and be seperated.

Protein molecules in solution can be separated from each other by taking advantage of their net charges. In the electric field between two electrodes, a positively charged particle moves toward the negative electrode and a negatively charged particle moves toward the positive electrode. This movement, known as electrophoresis, varies with the strength of the electric field, the charge of the particle, the size and shape of the particle, and the buffer/polymer gel combination through which the protein is moving. The...

Gel electrophoresis. Polypeptides can be separated by electrophoresis according to their relative content of acidic and basic residues. The isoelectric point (pI) of a polypeptide is the pH at which its net charge is zero. (See Fig 3.11 of your textbook). A) At physiological pH (= 7.4), what is the net charge on the tripeptide Asp-Arg-Glu-His? B) Calculate the pI of this tetrapeptide. [Hint: Using the pK, values in Table 2.1 and the Henderson-Hasselbalch equation, determine the pH when the...
