Synonyms

Complement C5, C5, CPAMD4

Source

Biotinylated Human Complement C5, His,Avitag (CO5-H82E9) is expressed from human 293 cells (HEK293). It contains AA Gln 19 - Arg 677 & Thr 678 - Cys 1676 (Accession # P01031-1).

Predicted N-terminus: Gln 19 (β chain) & Thr 678 (α chain)

Molecular Characterization

Other Tags and Version Biotin & Other Labeled Version

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 73.9 kDa (β chain) and 116.1 kDa (α chain). The protein migrates as 75 kDa, 120 kDa and 200 kDa under reducing (R) condition, and 200 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.

Labeling

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

Protein Ratio

Passed as determined by the HABA assay / binding ELISA.

Purity

>95% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

Formulation

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