Scientific Background
Cynomolgus monkey (Macaca fascicularis) CD46-BC, also known as membrane co-factor protein, a.a. 35-328 with C-terminal His-tag, expressed in a HEK293 cell expression system. MW = 36.5 kDa (precursor), 34.2 kDa (mature). Note: this protein is expressed with a 34 amino acid signal sequence that is cleaved after secretion and is heavily glycosylated, resulting in a protein that runs at a higher apparent MW.
Product Description
Mammalian (HEK293) ExpressionRecombinant CD46-BC Monkey protein is produced using a validated Mammalian (HEK293) expression system and supplied in aqueous buffer solution. Suitable for enzyme kinetics, inhibitor screening, binding assays, structural studies, and related biochemical research applications.

Safety & Handling
Avoid freeze/thaw cycles. Storing diluted protein is not recommended, if necessary, use carrier protein (BSA 0.1 - 0.5%).
This protein was produced in Mammalian (HEK293). Expression system selection determines post-translational processing, disulfide bond formation, and co-factor incorporation — all of which affect enzymatic activity. Insect cell (Sf9) systems are preferred for kinases and multi-subunit enzymes that require phosphorylation or chaperone assistance; E. coli is used for structurally simpler proteins.
This protein spans amino acids 35-328. Confirm the region includes your domain of interest — the active site, binding pocket, or substrate recognition sequence — before placing your order. Refer to the UniProt database for domain annotation.
Purity is assessed by SDS-PAGE; see the Certificate of Analysis. A gel image is provided with each lot. BPS Bioscience performs rigorous QC on each lot, including purity assessment and functional activity testing where applicable. Contact technical support if purity ≥99% is required for biophysical measurements.
Useful for studies of protein function and protein-protein interaction. Refer to the product datasheet for validated protocols and recommended assay conditions. Contact BioHippo technical support for application-specific guidance.
At least 6 months at -80°C. Avoid repeated freeze-thaw cycles — prepare single-use working aliquots. Add BSA or glycerol to aliquots if storing diluted enzyme is necessary. Typical stability is at least 6 months at −80°C.
