(±)8-Amino-7-Oxononanoic acid ((±)8-KAPA) is a racemic mixture of 8(R)-KAPA and the vitamer of biotin 8(S)-KAPA .[1],[2] It is biosynthesized as the 8(S) form but racemizes in culture media in a pH-dependent manner, with a higher racemization rate under very low (pH <2), physiological, and basic pH conditions.[2] 8(S)-KAPA increases proliferation in S. cerevisiae in a concentration-dependent manner and is an intermediate in the biosynthesis of biotin in microbes. 8(S)-KAPA, but not 8(R)-KAPA, is a substrate for E. coli and M. tuberculosis 7,8-diaminopelargonic acid aminotransferase (DAPA AT), which leads to accumulation of 8(R)-KAPA in M. tuberculosis cultures after exogenous application of racemic KAPA.

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。
