Histone H3 (1-25) amide (human, mouse, rat, porcine, bovine) (trifluoroacetate salt)
(Synonyms: ARTKQTARKSTGGKAPRKQLATKAA-NH2) 目录号 : GC45474A peptide fragment of histone H3
Sample solution is provided at 25 µL, 10mM.
Histone H3 (1-25) amide is an N-terminal peptide fragment of histone H3 that corresponds to amino acid residues 2-26 of the human histone H3 sequence. Histone H3 (1-25) amide contains lysine residues at positions 4 and 9 that are subject to methylation and acetylation and a serine residue at position 10 that is subject to phosphorylation, all of which have a role in the regulation of gene expression.1 Histone H3 (1-25) amide has been used to determine the substrate specificity of histone methyltransferases (HMTs).2 It is a more efficient substrate for HMT G9a than histone H3 (15-39) and full-length histone H3.

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。
