Complement C4-B (C4b), partial, mouse, recombinant

Organism: Mus musculus (Mouse). Source: E.coli. Expression Region: 1448-1738aa. Protein Length: Partial. Tag Info: N-terminal 6xHis-tagged. Target Protein Sequence: EAPKVVEEQE SRVQYTVCIW RNGKLGLSGM AIADITLLSG FHALRADLEK LTSLSDRYVS HFETDGPHVL LYFDSVPTTR ECVGFGASQE VVVGLVQPSS AVLYDYYSPD HKCSVFYAAP TKSQLLATLC SGDVCQCAEG KCPRLLRSLE RRVEDKDGYR MRFACYYPRV EYGFTVKVLR EDGRAAFRLF ESKITQVLHF RKDTMASIGQ TRNFLSRASC RLRLEPNKEY LIMGMDGETS DNKGDPQYLL DSNTWIEEMP SEQMCKSTRH RAACFQLKDF LMEFSSRGCQ V. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Non-enzymatic component of C3 and C5 convertases and thus essential for the propagation of the classical complement pathway. Covalently binds to immunoglobulins and immune complexes and enhances the solubilization of immune aggregates and the clearance of IC through CR1 on erythrocytes. Catalyzes the transacylation of the thioester carbonyl group to form ester bonds with carbohydrate antigens.
