一般建议为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。

资料参考

Hemin chloride is an oxidized form of heme that inhibits eukaryotic translation initiation factor 2α kinase 1 (eIF2αK1), a repressor of eIF-2α [1].

The eukaryotic initiation factor 1 (eIF1) plays an important role in translation start site specificity. The eIF2α is a key target in translational regulation. Phosphorylation of eIF2α on Ser51 converts eIF2 from a substrate to a competitive inhibitor of its exchange factor, eIF2β[2].

In vitro: The addition of hemin (30 μM) depressed the extent of incorporation of phosphate into eIF-2β by about 50% [1]. Concentrations of 25 μM hemin significantly decreased the rate of incorporation of phosphate into eIF-2α. Concentrations of hemin ranged from 20 to 40 μM maintained an optimal rate of protein synthesis in cell lysates [1].

In vivo: In mice, pretreated with an intraperitoneal injection of hemin displayed a marked induction of HO-1. In hemin-treated mice, thrombus formation was delayed, and the delay was completely blunted by tin protoporphyrin-IX [3].
