The target protein is expressed with sequence (Met1-Asp705) of human Complement C1r subcomponent (Accession #NP_001724.3) fused with a 6×His tag at the C-terminus.\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: C1R, EDSPD1\u003c\/p\u003e\n\n\u003cp\u003eSWISS: P00736\u003c\/p\u003e\n\n\u003cp\u003eGeneID: 715\u003c\/p\u003e\n\n\u003cp\u003eSpecies: Human\u003c\/p\u003e\n\n\u003cp\u003ePurity: ≥ 95 % as determined by SDS-PAGE.\u003c\/p\u003e\n\n\u003cp\u003eStorage: Store at -20℃. Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.\u003c\/p\u003e\n\n\u003cp\u003eBackground: The classical complement pathway plays a major role in innate immunity against infection. This pathway is triggered by C1, a multimolecular complex composed of the recognition protein C1q and two serine proteases, C1r and C1s. Following the C1q recognition, C1r is autoactivated, and in turn activates C1s, which cleaves C4 and C2, the C1 substrates. C1r acts by transforming the activation signal into an enzymic activity. C1r is a single-chain glycoprotein which can be cleaved into an A chain and a B chain upon activation. This protien recognizes full-length C1r chain and the cleaved B chain.\u003c\/p\u003e \n\n\u003cp\u003eBio-Activity: Measured by its ability to cleave a colorimetric peptide substrate, N-carbobenzyloxy-Gly-Arg-ThioBenzyl ester (Z-GR-SBzl), in the presence of 5,5’Dithio-bis (2-nitrobenzoic acid) (DTNB).The specific activity is \u0026gt;2828 pmol\/min\/μg, as measured under the described conditions.\u003c\/p\u003e\n\n\u003cp\u003eSource: HEK293 cells\u003c\/p\u003e\n\n\u003cp\u003eTag: C-His\u003c\/p\u003e\n\n\u003cp\u003eFormulation: Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
