生物活性/药理作用 | Bromelain is a cysteine endopeptidase with broad specificity for cleavage of proteins. Bromelain may be from a stem or piece of fruit. The product is from pineapple stem. Product P3169 (pGlu-Phe-Leu-p-nitroanilide) may be used as a chromogenic substrate for the assay of bromelain. |
应 用 | 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 . |
样品准备说明 | The product may be suspended in acetate buffer, pH4.5 at 1mg/mL concentration, yielding a hazy, off-white suspension. |
有效单位定义 | 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 (pH4.5 at 45°C) is equivalent to
approximately 1.7 new units (pH4.6 at 25°C). |
