N-(Boc-PEG4)-N-bis(PEG4-propargyl) is a trifunctional chemical containing two terminal alkynes and a Boc-protected primary amine. The terminal alkynes are used in copper click chemistry with azides to form stable triazole linkages with the target molecule while the carboxylic acids are reactive towards alcohols and primary amines to form esters and amides respectively.

Usages:
For differentiation of enterobacteriaceae.
Principle:
Peptone, beef extract powder and yeast extract powder provide nitrogen, vitamins, minerals; lactose, dextrose into fermentable sugars, which produce acid when measured by the phenol red indicator, acid yellow, basic red; thiosulfate sodium can be reduced to some bacteria to hydrogen sulfide, to produce a black iron sulfide and iron salts; sodium chloride to maintain osmotic equilibrium; agar as medium coagulant.
