애플리케이션

Bromelain from pineapple stem has been used as a positive control in sodium dodecyl sulfate (SDS) / polyacrylamide gel electrophoresis (PAGE) zymograms.[1] It has also been used as a Azocasein substrate for the determination of proteolytic activity.[2]
Bromelain may be used to inhibit the biosysnthesis of proinflammatory prostaglandins. It may be used to reduce clotting efficiency. Bromelain, from pineapple stem, has been used to make enzymatic hydrolysates of honeybee-collected pollen [3].

생화학적/생리학적 작용

Bromelain is a cysteine endopeptidase with broad specificity for cleavage of proteins. Bromelain may be from a stem or piece of fruit. Product P3169 (pGlu-Phe-Leu-p-nitroanilide) may be used as a chromogenic substrate for the assay of bromelain.

단위 정의

One unit will release 1.0 μmole of p-nitrophenol from N-α-Z-L-lysine p-nitrophenyl ester per min at pH 4.6 at 25 °C.

물리적 형태

Lyophilized powder containing mannitol and potassium phosphate buffer salts

제조 메모

Chromatographically purified
Chromatographically purified. Dissolves in water at 1 mg/mL concentration to form a clear, colorless solution.
