Function

Serine protease component of the complement C1 complex, which catalyzes cleavage and activation of C2 and C4, the next components of the classical complement pathway. Also cleaves IGFBP5 and thereby inhibits the trophic effects of IGF1.

Biological Context

Subcellular Location: Secreted; Cell surface
Tissue Specificity: Specifically expressed in male reproductive tissues

Product Specifications

Recombinant Mouse Complement C1s-B subcomponent (C1sb) is a recombinant protein from Mus musculus (Mouse), expressed in E.coli, covering amino acids 16-688aa, with N-terminal 10xHis-tagged and C-terminal Myc-tagged tag, molecular weight 82.4kDa, purity Greater than 85% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.

SDS-PAGE: Single band at expected molecular weight confirming purity.

ELISA: Suitable as coating antigen or detection standard.

Western Blot: Compatible with standard Western Blot protocols.

Protein Interaction: Validated for SPR (Surface Plasmon Resonance) and BLI (Bio-Layer Interferometry) studies.

Shipping: Shipped at ambient temperature. Lyophilized protein is stable during transit.

Storage: Store lyophilized protein at -20°C to -80°C. Reconstituted protein should be aliquoted and stored at -80°C. Avoid repeated freeze-thaw cycles.

Subunit

Core component of the complement C1 complex, a calcium-dependent complex composed of 1 molecule of the C1Q subcomplex, 2 molecules of C1R and 2 molecules of C1S. The C1Q subcomplex is composed 18 subunits: 3 chains of C1QA, C1QB, and C1QC trimerize to form 6 collagen-like triple helices connected to six globular ligand-recognition modules
