chromogenic substrates การใช้

• Also during 1964, he published the first production and demonstration of X-gal as a chromogenic substrate.
• They proposed a cytochemical assay based on production of a blue-dyed precipitate that results from the cleavage of the chromogenic substrate X-Gal.
• Some of the most common HRP chromogenic substrates, luminol is the exception in which a fluorophore is generated after the HRP-catalyzed reaction rather than a chromophore.
• HRP catalyzes the conversion of chromogenic substrates ( e . g ., DAB, ABTS ) into colored products, and produces light when acting on chemiluminescent substrates ( e . g.
• The first screening technique used is called ELISA . The hybridoma culture supernatant, secondary enzyme labeled conjugate, and chromogenic substrate, are then incubated, and the formation of a colored product indicates a positive hybridoma.
• Another application involves diluting enzyme stocks into solution containing a chromogenic substrate, or diluting antigens into solutions for ELISA ( Enzyme-Linked ImmunoSorbent Assay ) or some other antibody cascade detection reaction, to measure the original concentration of the enzyme or antigen.
• "' 3, 3, 5, 5-Tetramethylbenzidine "'or "'TMB "'is a chromogenic substrate used in staining procedures in immunohistochemistry as well as being a visualising reagent used in enzyme-linked immunosorbent assays ( ELISA ).
