Technical Data
Complement 1s (Complement Component 1 s Subcomponent, Basic Proline-rich Peptide IB-1, C1 Esterase, Complement C1s Subcomponent Precursor)
C1 component of human complement is a complex of three glycoproteins: C1q, C1r and C1s. C1s has a molecular weight of 83000 and is present in plasma in an average concentration of 50mg/ml, either as a complex with C1q and C1s or in the absence of C1q as a tetramer with C1s. The subcomponents of the C1 complex are responsible for the initiation of the classical pathway of complement activation.

Suitable for use in use ELISA, Immunoelectrophoresis and Radial Immunodiffusion. Other applications not tested.

Recommended Dilution:
Optimal dilutions to be determined by the researcher.

Human C1s isolated as a homogenous protein
Supplied as a lyophilized powder. Preservative free. Reconstitute with 1ml sterile ddH2O. Dilute further in PBS, pH 7.2.
Recognizes human C1s. In immunoelectrophoresis and radial immunodiffusion (Ouchterlony) against fresh normal human plasma a single precipitin line is obtained which shows a reaction of identity with the precipitin line obtained with purified C1s protein. May also react with complexes containing C1q. No reaction is obtained with C1q, C1r or any other plasma protein component or serum. Does not crossreact with any other component of human plasma.
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
