GeneAb™ CD57

Propargyl-PEG10-NHS ester serves as a bifunctional PEG linker with a terminal propargyl that participates in click reactions with azide-bearing moieties and an NHS ester group that reacts readily and efficiently with amine-bearing molecules. The PEG10 units improve the water solubility of the molecule. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Introduction

Usages:

For enrichment of bacteria of cosmetics and disposable hygiene products.

Principle:

 Casein peptone and soybean peptone provide the nitrogen source, vitamins, and growth factors; sodium chloride to maintain osmotic balance; dipotassium hydrogenphosphate as a buffer; lecithin and Tween 80 can neutralize preservatives and can play a dispersed material in the emulsion features, lecithin can neutralize quaternary ammonium salt, Tween 80 neutralizes phenols, hexachlorophene, formalin, a combination that can neutralize and ethanol.
