CMP-Sialic acid is a form of the sugar N-acetylneuraminic acid (Neu5Ac) O-linked with the nucleotide cytidine-5’-monophosphate (CMP). In vertebrates, it is biosynthesized within the nucleus from CTP and Neu5Ac by CMP-sialic acid synthetases.[1] Sialyltransferases transfer Neu5Ac from CMP-sialic acid to various acceptor substrates, most commonly at terminal positions of the oligosaccharide component of glycoproteins or glycolipids.[2],[3] Sialic acid-containing glycans at the cell surface play important roles in cell interactions and have roles in infection, inflammation, and cancer.[3],[4],[5]

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。
