Because PAGE gels are used to look a protein and ethidium bromide only stains double stranded nucleic acids.

What is denaturing sds page?

Sodium dodecyl sulphate (SDS) is an anionic detergent which denatures proteins by "wrapping around" the polypeptide backbone - and SDS binds to proteins fairly specifically in a mass ratio of 1.4:1. In so doing, SDS confers a negative charge to the polypeptide in proportion to its length - ie: the denatured polypeptides become "rods" of negative charge cloud with equal charge or charge densities per unit length. It is usually necessary to reduce disulphide bridges in proteins before they adopt the random-coil configuration necessary for separation by size: this is done with 2- mercaptoethanol or dithiothreitol. In denaturing SDS-PAGE separations therefore, migration is determined not by intrinsic electrical charge of the polypeptide, but by molecular weightAnd for the actual experiment beyond the denaturing: PAGE stands for polyacylamide gel electrophoresis. This is a procedure that separates proteins by size by running them through a gel "matrix" so that the smaller ones travel faster that the larger ones. This is achieved by creating an electric field with the sds-protein complex traveling toward the positively charged end of the gel. Once the smallest proteins have traveled most of the way across the gel the current is turned of and the gel is removed and stained with dye that binds protein so that you can see where it is in the gel.


What is the minimum amount of protein that can appear in SDS PAGE gel?

Although this would in part depend the size of the protein being separated and stained (for some staining methods), the largest factor that determines sensitivity of SDS-PAGE is the type of staining method used: - If staining is done with coomassie brilliant blue, the limit of detection claimed by most suppliers is 50 ng. In my experience, 100-1000 ng is more accurate for proteins of 20-30 kDa. - If staining is done with silver stain, the limit of detection is much lower (or higher sensitivity). Manufacturers usually claim that 5-50 ng of protein can be visualized, but in my experience 50 ng is the lower limit for average sized proteins (20-30 kDa). - If visualization is accomplished with an enzyme immunoassay, the limit of detection is lower still, as low as 0.1-1 ng (100-1000 pg). - If visualization is accomplished with radio immunoassay the limit of detection becomes much lower again, easily to the picogram level (0.001 ng).


Purpose of gel electrophoresis?

Polyacrylamide gel electrophoresis (PAGE) is used to separate large biomolecules, such as RNA, DNA and proteins, by their size, shape and charge. Proteins can be separated based on their size alone if the sample is treated with a denaturing agent first, such as sodium dodecyl sulfate (SDS). Nucleic acid samples can be separated on size alone through the use of an agarose gel.
