    2020-10-14 · Western blots, in contrast, diffuse antigens in polyacrylamide gel by electrophoresis. A negative charge is applied to the gel. The native proteins, which are made up of amino acids, carry a net negative charge when at a pH above their Isoelectric point (pI). As a result, the proteins migrate up the gel, which acts as a molecular sieve.

    Abstract. A combination of quantitative immunoelectrophoresis and sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis was used to determine location and molecular weights of surface membrane antigens of four strains of Mycoplasma arginini. Two major surface antigens were identified for M. arginini by absorption of antiserum with whole cells: one surface antigen was strain specific ...
