Stem bromelain
Based on 1 Customer Validation
Stem bromelain (EC 3.4.22.32) is a cysteine protease and antibacterial agent. Stem bromelain can be isolated from the stem of the pineapple (Ananas comosus). Stem bromelain induces dose-dependent secretion of IL-12p70, and IL-6, induces Apoptosis, causes cleavage of full-length PARP protein, Caspase 3, and Caspase 9, increases Bax, and decreases Bcl-2. Stem bromelain possesses various fibrinolytic, antiedema, antithrombotic, and anti-inflammatory activities. Stem bromelain also exhibits in vivo antitumor and antileukemic activities, as well as antimetastatic effects. Stem bromelain has antimycobacterial activity. Stem bromelain provides protection against lead poisoning.

Stem bromelain (10-50 μg/mL; 12 h) causes Apoptosis, increases the expression of CD80, CD86, results in the dose-dependent secretion of IL-12p70, TNF-α, and IL-6 in peritoneal macrophages[3].
