                          60% and temperature below 25℃. The shelf life is 12 months, and the shelf life is 
                          24 months under 5 ~ 15℃ cool, low temperature and dry environment.

储存时间：      Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt.
                           Reconstituted protein solution can be stored at 2-8°C for 2-7 days.
                           Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months.

运输：             This product is transported at low temperatures.

                       Upon receipt, store it immediately at the temperature listed below.

背景：            菠萝蛋白酶:菠萝组织中有一种酶可以水解蛋白质，这种酶被称为菠萝蛋白酶。它是一种半胱氨酸内肽酶，具有广泛的蛋白质裂解特异性，可用于抑制促炎前列腺素的生物合成，以降低凝血效率。从菠萝茎中提取菠萝蛋白酶，用于制备蜜蜂采集花粉的酶解产物。菠萝蛋白酶也可能来自干果或水果。产物P3169 (Glu-PHE - leu - p - nitro苯胺)可作为显色底物测定菠萝蛋白酶的含量。

Bromelain Protease: There is an enzyme that hydrolyzes protein in the tissues of the pineapple, and it is called bromelain. It is a cysteine endopeptidase that has broad specificity for protein cleavage and can be used to inhibit the biosynthesis of proinflammatory prostaglandins for reducing coagulation efficiency. Bromelain from pineapple stems has been used to prepare enzymatic hydrolysis products of pollen collected by bees. Bromelain may also come from dry or fruit. Product P3169 (Glu-PHE - LeU-P-nitroaniline) can be used as a chromogenic substrate for the determination of bromelain content.
