Complement C5, C5, CPAMD4

表达区间及表达系统（Source）

Biotinylated Rat Complement C5 Protein, His,Avitag (CO5-R82E3) is expressed from human 293 cells (HEK293). It contains AA Gln 24 - Arg 683 & Asp 684 - Ala 1688 (Accession # NP_444179.1).

Predicted N-terminus: Gln 24 (β chain) & Asp 684 (α chain)

蛋白结构（Molecular Characterization）

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™). The mature form of Complement C5 is a disulfide-linked heterodimer composed of proteolytically cleaved α and β chain. Each α and β chain has a calculated MW of 74.1 kDa (β chain) and 116.5 kDa (α chain). The protein migrates as 70 kDa, 120-130 kDa and 180 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

标记（Labeling）

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

蛋白标记度（Protein Ratio）

Passed as determined by the HABA assay / binding ELISA.

纯度（Purity）

>95% as determined by SDS-PAGE.

制剂（Formulation）

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
