애플리케이션

Bromelain from pineapple stem has been used:
  • to evaluate the aqueous micellar two-phase systems composed of ionic liquids as co-surfactants
  • as a positive control in sodium dodecyl sulfate (SDS) / polyacrylamide gel electrophoresis (PAGE) and in cells proliferation assay
  • to study its potential analgesic effect and to evaluate its hydrolyzingeffects on proenkephalin (PENK)-derived peptides containing enkephalin sequences

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 .

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 B4882 is from pineapple stem. 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 micromole of p-nitrophenol from N-alpha-CBZ-L-Lysine p-nitrophenyl ester per minute at pH 4.6 at 25 °C. One old titrimetric unit (pH 4.5 at 45 °C) is equivalent to approximately 1.7 new units (pH 4.6 at 25 °C).

제조 메모

The product may be suspended in acetate buffer, pH 4.5 at 1 mg/mL concentration, yielding a hazy, off-white suspension.
