表达区间及表达系统(Source)
GMP Human VCAM-1 Protein, Fc Tag (GMP-VC1H25) is expressed from human 293 cells (HEK293). It contains AA Phe 25 - Glu 698 (Accession # P19320-1).
Predicted N-terminus: Phe 25
蛋白结构(Molecular Characterization)
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 100.7 kDa. The protein migrates as 126 kDa±5 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 10 EU/mg by the LAL method.
蛋白A残留(Protein A)
<5 ppm of protein tested by ELISA.
宿主蛋白残留(Host Cell Protein)
<0.5 ng/µg of protein tested by ELISA.
宿主核酸残留(Host Cell DNA)
<0.02 ng/μg of protein tested by qPCR.
无菌(Sterility)
The sterility testing was performed by membrane filtration method described in CP<1101>, USP<71> and Eur. Ph. 2.6.1.
支原体(Mycoplasma)
Negative.

背景(Background)
血管细胞粘附蛋白1(VCAM-1)也称为CD106、INCAM-100和L1CAM,是一种属于免疫球蛋白超家族的细胞表面唾液酸糖蛋白。VCAM-1/CD106含有7个Ig样C2型(免疫球蛋白样)结构域。CD106/VCAM-1在炎症的血管内皮细胞上表达,在正常和炎症组织中的巨噬细胞样细胞和树突状细胞类型上也表达。L1CAM/VCAM-1在细胞识别中很重要,似乎在白细胞-内皮细胞粘附中起作用。CD106/VCAM-1与白细胞上的β-1整合素VLA4相互作用,介导粘附和信号转导。VCAM-1/VLA4相互作用可能在免疫反应和白细胞向炎症部位迁移中发挥病理生理作用。INCAM-100/VCAM1与ECMV-D衣壳蛋白结合,并作为该病毒的受体。
