VWR 2-Mercaptoethanol ≥99%, Proteomics Grade

2-Mercaptoethanol (β-Mercaptoethanol) is a high-purity reducing agent specifically formulated for proteomics, genomics, and molecular biology applications. With a purity of ≥99% and confirmed absence of DNase, RNase, and protease activity, this proteomics-grade reagent is ideal for protein denaturation, RNA stabilization, and enzyme inactivation protocols.

Commonly used in SDS-PAGE sample buffers, reducing environments for disulfide bond cleavage, and nucleic acid isolation protocols, this reagent is supplied in amber bottles to protect it from light degradation and ensure optimal stability.
