Lesofavumab (MHAB5553A) is a human IgG1κ anti-influenza B virus antibody.
Lesofavumab (MHAB5553A) binds to a conserved epitope in the vestigial esterase domain of hemagglutinin (HA), a major immunodominant surface glycoprotein on influenza B viruses, and blocks HA-mediated membrane fusion in the endosome[1].Lesofavumab (46B8) is able to neutralize all eleven IBV strains tested that were associated with human infections spanning >70 years, with IC50 values ranging from 0.58 to 0.95 nM[2].Lesofavumab (46B8; 0-100 ng/mL) blocks membrane fusion and induces antibody-dependent cellular cytotoxicity (ADCC) in vitro[2].
Lesofavumab (46B8; 15 mg/kg; i.v.; single dose) is able to protect mice against lethal challenge of the mutant influenza B virus[2].

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。
3. 以上所有助溶剂都可在 GlpBio 网站选购。
