Rabbit Complement C5 Protein, His Tag

Synonyms

Complement C5, C5, CPAMD4

Source

Rabbit Complement C5, His Tag (CO5-R52H4) is expressed from human 293 cells (HEK293). It contains AA Gln 19 - Arg 677 & Met 678 - Ala 1678 (Accession # XP_008271599.1).

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. The mature form of Complement C5 is a disulfide-linked heterodimer composed of proteolytically cleaved α and β chain. During cultivation, Complement C5 will be partially processed into α and β chain and has a calculated MW of 73.8 kDa (β chain) and 111.9 kDa (α chain) respectively. The protein migrates as 80 kDa, 120 kDa and 200 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>90% as determined by SDS-PAGE.

Formulation

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