Margetuximab (2-4 mg/kg; IP 5 or 6 times at weekly) can firstly and significantly reduces the tumor size at day 30 - 37 in mice model[1].
Margetuximab (15-150 mg/kg; IV; 6 weekly) exhibits well tolerated in cynomolgus monkeys, decreases NK cells by an average of 51%, and induces IL-6 release[1].
Margetuximab (50 mg/kg; IV; single dosage) exhibits favorable safety profile[1].

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。
