Dictionary » G » Gel GelGel jelly like material formed by the coagulation of a colloidal liquid. Many gels have a fibrous matrix and fluid filled interstices: gels are viscoelastic rather than simply viscous and can resist some mechanical stress without deformation. Examples are the gels formed by large molecules such as collagen (and gelatin), agarose, acrylamide and starch. ![]()

SDS-PAGE gel and Rf valuesHello, I have to calculate the Rf for the molecular weight markers in lane one of the gel that I attached. When I do this and graph the Rf values against the molecular weight my graph is not linear. I marked in red where I am measuring from. Can someone please tell ...

Protein ladder width increases down the gel?... weight of proteins when running a SDS-PAGE. I have conjugated several different molecular weight proteins with dyes and ran them on a 12% gel. There is no problem with the size when I loaded each protein into a separate well, but when I combined all of the proteins together into 1 well, ...

DNA... doesn't cut between every histone; then you would see some double-length fragments, triple-length fragments etc. If you run the fragments out on a gel you would see a ladder and analysis of the masses of the ladder rungs would reveal that they are integer multiples of the mass of the smallest rung ...
