Penicillin G-d5 is intended for use as an internal standard for the quantification of penicillin G by GC- or LC-MS. Penicillin G is a β-lactam antibiotic that is effective mainly for Gram-positive bacteria.1 It has MIC90 values of 0.03, 1, and 4 µg/ml for penicillin-susceptible, -intermediate, and -resistant strains of S. pneumoniae, respectively, and 16-128 µg/ml for various Bacteroides isolates in a broth dilution assay.2,3 Formulations containing penicillin G have been used for the treatment of bacterial infections and in livestock production.

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。
