Description_x000D_ General description_x000D_ Elastin−Congo red is a substrate-dye conjugate and is used in agar medium to probe elastase activity. The presence of elastase functionality leads to cleavage of the dye from the elastin substrate._x000D_ Application_x000D_ Elastin−Congo red has been used as a substrate for neutrophil elastase, salivary elastase and P. aeruginosa._x000D_ Packaging_x000D_ 5 g in glass bottle_x000D_ Other Notes_x000D_ Elastin impregnated with Congo red dye._x000D_ Substrates_x000D_ Substrate for the estimation of elastase.
