Formula of Egg white lysozyme (19-36) [Gallus gallus]:
C86H144N28O23S2
Hen egg white lysozyme has a molecular weight of about 14,600 and each molecule comprises 129 amino acid residues1.
The crystals have unit cell dimensions a = b = 79.1, c = 37.9 A and space group P43212, and there are eight molecules in the unit cell, one per asymmetric unit2. Liquid of crystallization constitutes about 33.5 per cent of the weight of the crystal3.
The activity of lysozyme in promoting the dissolution of bacterial cell walls is now known to depend upon its ability to catalyze the hydrolysis of ,3-(1-4) glycosidic linkages between amino sugar residues in poly-saccharide components of these cell walls1.

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。
