- In protein electrophoresis, what reagent present in the sample buffer is used to eliminate differences in the charge densities of proteins? Tris-HCL ph 8.8 2-mecraptothanol SDS(sodium dodecyl sulfate) Tris-HCL PH 6.8When separated on a polyacrylamide gel, the procedure is abbreviated as SDS-PAGE (Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis). The technique is a standard means for separating proteins according to their molecular weight. The gels are neutral, hydrophilic, three-dimensional networks of long hydrocarbons cross-linked by methylene groups. (Give the main two compounds responsible for the formation of the gels)Describe the principles involved in the separation of proteins by sodium dodecyle sulphate (SDS) PAGE and isoelectric focusing.

I, III and Vd. I, II, and IV Which of the following statements are TRUE about the discontinuous gel in SDSPAGE?I. The sandwich effect occurs because of the lower mobility of the zwitterionic form of glycine compared to the protein band in the stacking gel.II. Because of the larger pores in the resolving gel, proteins move faster in the stacking gel, but decelerate at the boundary of the two gels.III. In the stacking gel, in terms of net negative charge of the species, the order is: zwitterionic glycine > proteins > chloride ion.IV. The higher pH in the resolving gel allows glycine to carry a more negative charge, resulting in higher mobilities compared to…
