【預期用途】
本產品用于定量測定血清、血漿和尿液中游離的和非肌動復合物結合的維生素D結合蛋白(VDBP)。僅供科研使用。僅用于體外診斷。
【背景知識】
維生素D結合蛋白(VDBP,也稱為組特異性組分/Gc蛋白)是在肝臟中形成的一種多功能血清蛋白。由懷孕或激素避孕引起的高雌激素水平會刺激其合成。VDBP可在血漿、腹水、液體、尿液以及各種類型的細胞表面發(fā)現。 在血液中,VDBP與循環(huán)中的大部分25-OH維生素D結合,并將其帶入腎臟,在腎臟中轉化為1,25-(OH)2維生素D激素。 此外,VDBP以1:1的比例與單分子肌動蛋白結合。肌動蛋白是一種細胞內蛋白質,可以作為單體或單絲。大量組織破壞或細胞死亡導致肌動蛋白的血漿水平顯著升高,從而形成VDBP肌動蛋白復合物,并迅速被清除。因此,創(chuàng)傷或膿毒癥患者的VDBP水平迅速下降,特別是多器官功能衰竭水平高的患者。 此外,VDBP是免疫調節(jié)蛋白Gc-MAF(Gc蛋白衍生的巨噬細胞活化因子)的前體,它增加了巨噬細胞抗腫瘤的活性。
樣本要求:血清、血漿和尿液樣本
