Sample solution is provided at 25 µL, 10mM.
DL-Homocysteine is a thiol-containing amino acid derived from methionine.1 It inhibits vasodilation of precontracted isolated guinea pig pulmonary artery rings induced by acetylcholine (ACh) and enhances potassium chloride- and phenylephrine-induced contraction of isolated guinea pig pulmonary artery rings.2 DL-Homocysteine (200 ?M) inhibits endothelium-dependent ACh-induced vasodilation in the vascular bed of isolated perfused rat pancreas.3 Elevated plasma levels of DL-homocysteine are positively correlated with occlusive arterial diseases and atherosclerosis.1,2

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。
3. 以上所有助溶剂都可在 GlpBio 网站选购。
