Source

Biotinylated Cynomolgus Complement C5 Protein, His,Avitag (CO5-C82E3) is expressed from human 293 cells (HEK293). It contains AA Gln 19 - Arg 677 & Met 678 - Cys 1676 (Accession # XP_005580972.1).

Predicted N-terminus: Gln 19 (β chain) & Met 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 116.2 kDa (α chain). The protein migrates as 70 kDa and 120-130 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE).

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.

Formulation

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