Melittin is a small protein that is the principal cytotoxic component of venom of the honey bee, A. mellifera.1 Structurally, melittin consists of two α-helical segments forming a bent rod, with hydrophilic residues on the convex side and hydrophobic sites on the concave side.1,2 This allows melittin molecules to assemble as tetramers on membrane surfaces and form pores, resulting in cell death. Bee venom is also known to stimulate phospholipase A2 (PLA2) activity, and this may be linked to melittin-mediated pore production as well as the presence of low molecular weight PLA2 enzymes in the venom.2,3 Melittin also has antimicrobial properties, which, combined with its cytolytic properties, extends its potential for therapeutic applications.3

计算结果:
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。
