Human FOLR1 Protein, His Tag (MALS verified)
分子别名(Synonym)
FOLR-1, FBP, FOLR, FRα
表达区间及表达系统(Source)
Human FOLR1, His Tag (FO1-H52H1) is expressed from human 293 cells (HEK293). It contains AA Arg 25 - Met 233 (Accession # P15328-1).
Predicted N-terminus: Arg 25
蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 26.5 kDa. The protein migrates as 32-40 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素(Endotoxin)
Less than 0.1 EU per μg by the LAL method / rFC method.
纯度(Purity)
>95% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5 with trehalose as protectant.

背景介绍
叶酸受体1(FOLR1)——亦称叶酸受体α、叶酸结合蛋白(FBP)、FOLR——是叶酸受体家族成员。该基因家族对叶酸及其多种还原衍生物具有高亲和力,负责介导5-甲基四氢叶酸向胞内的转运。成熟FOLR1为N-糖基化蛋白,通过GPI锚定于细胞表面,主要在上皮细胞表达且在多种癌变组织中显著高表达。该受体经内化进入内体系统后与配体解离,最终循环至细胞膜表面。其可溶形式可通过酶切脱落进入血清及乳汁。FOLR1基因缺陷将导致脑叶酸转运缺陷性神经退行性病变(NCFTD),这是一种因婴幼儿期脑组织特异性叶酸缺乏引发的常染色体隐性遗传病。
