Supplier: Sigma Aldrich Fine Chemicals Biosciences A3219100ML

The product is supplied as a ready-to-use one component substrate for peroxidase consisting 2 2prime-azino-bis (3-ethylbenz-thiazoline-6-sulfonic acid) in an acidic buffer. The substrate is colorless before reacting with peroxidase and produces a blue-green color reaction product after reacting with it. 1% sodium dodecyl sulfate (SDS) may be used to stop the reaction during end-point assays. Since this substrate produces a soluble reaction product it is not recommended for immunoblotting or histochemical applications.
