anionic polyacrylamide electrophoresis in nepal

  • Agarose and Polyacrylamide Gel Electrophoresis

    Native polyacrylamide electrophoresis in the presence of two reversible protein anionic stains (Ponceau S and Ponceau 2R) was used to study the oligomeric states of soluble proteins. A mild binding of the used protein stains to nondissociated protein oligomers imposed a charge shift on the proteins resulting into separation of protein species according to their size under physiological conditions.

  • Native polyacrylamide electrophoresis in the presence

    1985-1-1 · INTRODUCTION The introduction of an anionic detergent, sodium dodecyl sulfate (SDS), in Polyacrylamide gel electrophoresis (Maizel, 1966) has initiated a revolution in the stucfy of membrane proteins. In the presence of SDS, the proteins unfold and form complexes with the detergent and therfore migrate as anions.

  • Two Dimensional Anionic-Cationic Detergents

    A defined mixture consisting of four sulfated alkyl detergents (dodecyl sulfate, tetradecyl sulfate, hexadecyl sulfate, octadecyl sulfate) as well as the four alcohols of corresponding aliphatic chain length was found to be effective at duplicating the electrophoretic effect of USP-grade SDS and thus changed the relative order and position of polypeptides on electrophoresis relative to conventional SDS-PAGE.
