VWR offers an extensive line of acrylamide and bis-acrylamide pre-weighed powder blends, pre-mixed stock solutions, and ready-to-use solutions for customized polyacrylamide gel electrophoresis of proteins and PAGE of nucleic acids. Our ultra pure (> 99.9%) acrylamide and bis-acrylamide powders provide the flexibility to prepare solutions having concentrations and ratios for all electrophoresis applications. Liquid blends minimize the handling of neurotoxic acrylamide.

Rapid Transfer Buffer is a simple, single component system for quick and efficient transfer of proteins from SDS-PAGE gels to membranes for Western blotting applications

Supplier: VWR

An excellent reagent for maintaining SH groups in reduced state; quantitatively reduces disulfides. DTT is effective in sample buffers for reducing protein disulfide bonds prior to SDS-PAGE. DTT can also be used for reducing the disulfide bridge of the cross-linker N,N′-bis(acryloyl)cystamine to break apart the matrix of a polyacrylamide gel. DTT is less pungent and is less toxic than 2-mercaptoethanol. Typically, a seven fold lower concentration of DTT (100 mM) is needed than is used for 2-mercaptoethanol (5% v/v, 700 mM).
