The FOCUS™ Reduction-Alkylation Kit offers a simple two-step method for reduction and alkylation of protein samples for 2D gel analysis.

The disulfide bonds are reduced with a highly reactive and stable TCEP [Tris (2-carboxyethyl) phosphine] followed by blocking of the thiols by alkylation with iodoacetamide reagent preparation.

The kit is supplied with proprietary buffers and reagents necessary for an efficient reduction and alkylation of the disulfide bridges while minimising reoxidation of the thiols.
