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。 |
Ercalcidiol是维生素D2的代谢产物,也是VDR样受体的配体[1]。
维生素D是一组脂溶性类固醇衍生物,对增强小肠吸收钙、铁、镁、磷酸盐和锌具有重要作用。Ercalcidiol(25-羟基维生素D2)和25-羟基钙化醇(亦称25-羟基维生素D2,缩写为25(OH) D2)是维生素D代谢产物,Ercalcidiol在肝中转化为25-羟基钙化醇。通过测量血清中Ercalcidiol和25-羟基钙化醇的含量能够反应人体内的维生素D水平[2] [3]。
利用离体灌注大鼠肾脏模型发现Ercalcidiol不仅转化成24,25-二羟维生素D2,同时也转化成另外两种代谢产物:24,25,28-三羟维生素D2和24,25,26-三羟维生素D2[4]。在刚断奶的雄性大鼠模型中,试验发现断奶早期一种蛋白缺乏或断食都不会影响血浆中Ercalcidiol和23,25-二羟维生素D的合成和转运[5]。
