GRADE & PURITYAnimal Free?Animal-free — produced without animal-derived components to reduce contamination risk. Use in biomanufacturing and culture avoiding animal-origin material.Carrier Free?Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays.His Tag?His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein.≥90%(SDS-PAGE)See COA

Recombinant Human Complement Component C1r Protein
Animal Free, Carrier Free, His-Tag, ≥90%(SDS-PAGE), See COA
Biochemical and Physiological Mechanisms
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 recognitio

Recombinant Human Complement Component C1r Protein (rp169560) - SDS-PAGE
3 μg/lane of Recombinant Human Complement Component C1r Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing a band at 18.1 & 36.1 kDa under reducing conditions and 51.2 kDa under non-reducing conditions.
Within the C1 complex, C1R is a dimer of identical chains, each of which is activated by cleavage into two chains, heavy and light, connected by disulfide bonds (PMID:2988513).
