Human COL1A1 Protein, His Tag, low endotoxin (MALS verified)
分子别名(Synonym)
COL1A1
表达区间及表达系统(Source)
Human COL1A1 Protein, His Tag (CO1-H5243) is expressed from human 293 cells (HEK293). It contains AA Leu 1229 - Leu 1464 (Accession # P02452).
Predicted N-terminus: His
蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 28.9 kDa. The protein migrates as 30-33 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 0.01 EU per μg by the LAL method.
纯度(Purity)
>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH7.5 with trehalose as protectant.

背景(Background)
I型胶原蛋白是皮肤、骨骼和肌腱等结缔组织中含量最丰富的结构蛋白。它被合成为一种前胶原分子,其特征是一个300 nm的三螺旋结构域,两侧是球形的N端和C端前肽。三螺旋结构域包含Gly-Xaa-Yaa三联体,其中Xaa和Yaa通常分别是脯氨酸和羟脯氨酸。非螺旋前肽被前胶原N-和C-蛋白酶活性去除,使成熟的三螺旋可以自组装成胶原纤维,为组织提供抗拉强度。I型胶原蛋白是一种由两条α1(I)链和一条α2(I)链路组成的异三聚体,尽管也有人描述了由三条相同的α1(Ⅰ)链组成的同源三聚体。
