Sample solution is provided at 25 µL, 10mM.
Procyanidin B3 is a polyphenol flavonoid dimer of (+)-catechin that has been found in G. biloba and has diverse biological activities.1,2,3 It inhibits aggregation of amyloid-β (1-42) with an IC50 value of 3.54 μM and destabilizes preformed Aβ42 fibrils (EC50 = 5.12 μM).1 Procyanidin B3 (1 mM) reduces oxidation of linoleic acid and scavenges 2,2-diphenyl-1-picrylhydrazyl free radicals in cell-free assays.2 It inhibits hydrogen peroxide-induced production of inducible nitric oxide synthase (iNOS) and apoptosis in primary murine chondrocytes.3 Procyanidin B3 (0.01 mg/kg) reduces chondrocyte apoptosis, pseudocapsule thickness, and the frequency of ectopic cartilage formation in a mouse model of surgically induced osteoarthritis.

工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
