C3 Protein


Purified human complement component C3.

Produktname C3 Protein
Kat-Nr. A113C


The third component of complement is a centrally important constituent of both the alternative and classical pathways. Upon secretion, pro-C3 undergoes a site specific proteolytic cleavage to yield circulating C3, a protein containing two disulfide bonded subunits (Alpha 115 kD and Beta 75 kD). The concentration of C3 in serum is approximately 1.25 +/- 0.52 mg/ml.

Concentration: 1.0 mg/ml
Volume/Vial: 250 µl/vial
Storage: at or below -70°C
Purity: > 95%
Buffer: PBS

Functional Testing:
All Quidel complement components are tested for functional activity in a standard lytic or applicable functional assay and for biochemical purity by SDS- polyacrylamide gel electrophoresis. Please refer to the Certificate of Analysis for lot specific information on functional titer.

Quidel's purified human complement components are useful in a wide variety of immunochemical and research applications.
