Hematin
(Synonyms: 羟高铁血红素) 目录号 : GC64092Hematin 是一种含铁卟啉,通过结合止血蛋白 (hemostatic proteins) 诱导其失活的机制抑制凝血因子 (clotting factors) 的活性以及纤维蛋白凝块 (fibrin clot) 的溶解。Hematin 可用于急性卟啉症和癌症的研究。
Cas No.:15489-90-4
Sample solution is provided at 25 µL, 10mM.
Hematin, an iron-containing porphyrin, inhibits the activity of clotting factors and also fibrin clot lysis through the mechanism of binding to and inactivation of hemostatic proteins[1]. Hematin can be used for the research of acute porphyrias and cancer[1][2][3][4][5].
Hematin (0.01 mg/ml) inhibits the clotting of bovine fibrinogen (1.3 to 2.6 mg/ml) by bovine thrombin (0.12 U/ml) and inhibits the hydrolysis of a synthetic substrate by human thrombin[2].Hematin (0.035 mg/ml) reduces VIII:C activity from 0.88 to 0.40 U/ml[2].Hematin (0.05 mg/ml) inhibits the activation of VIII:C by thrombin (0.04 U/ml)[2].Hematin (0.09 mg/ml) inhibits the hydrolysis of a synthetic substrate by plasmin[2].
Hematin (i.v.; single injection) suppressed porphyrin production in SD rat (weighing 160-205 g)[4].

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。
