Transverse pore gradient gel electrophoresis of lipoprotein [a] using methylenebisacrylamide gradients.

Abstract

We describe a modification of transverse pore gradient gel electrophoresis in which pore size is regulated by crosslinker proportion (%C) rather than by total monomer concentration (%T). We electrophoresed plasma lipoprotein [a] transversely across linear N,N'-methylenebisacrylamide gradients and measured mobility as a function of %C. This method allows for the simultaneous assessment of pore sizes generated over a wide range of crosslinker proportions.
