C1S Antibodies

AND C1S ELISA kits, C1S Proteins

Many biological assays use antibodies to detect C1S, such as Western Blot (WB), ELISA, Flow Cytometry, Immunocytochemistry (IHC). These antibodies can be polyclonal or monoclonal, and react with C1S in Human, Mouse, Rat, and many other animal samples. Boster Bio use mainly mouse and rabbit to develop C1S antibodies...

We validate the specificity of these antibodies to C1S by testing them on tissues known to express C1S positively and negatively. Browse below to find the C1S antibody that suites your experiment. We have 9 of these antibodies and many publications and validation images.

If you cannot find antibodies that fit your needs, contact us for making custom antibodies. We have a full suite of custom antibody services covering from research to diagnostic and therapeutic applications.

C1S Overview

Facts about Complement C1s subcomponent.

C1S 3D structure. Source: alphafold

Complement C1s subcomponent (C1S)

C1s B chain is a serine protease that combines with C1q and C1r to form C1, the first component of the classical pathway of the complement system. C1r activates C1s so that it can, in turn, trigger C2 and C4.
