C3 is the most abundant complement protein in guinea pig serum. Its biological function strongly resembles that of C3 in man and other laboratory animal species. It has a central role in the activation system being common in both pathways. Activation of C3 is achieved by specific limited proteolysis resulting in the increase of a number of degradation fragments. The anaphylatoxin C3a promotes smooth muscle
contraction and increases vascular permeability; the large C3b fragment is involved in binding to the complement activator and can interact with specific receptors to allow efficient clearance of the activating cell or particle; degradation fragments of C3b (C3bi, C3c, C3dg and C3d) are important in receptor binding and clearance mechanisms, in virus neutralization and possible in the immune response.
Applications:
Suitable for use in IEP, Single and Double RID. Other applications have not been tested.
Recommended Dilutions:
IEP: Use 2ul serum, plasma or equivalent against 120ul antiserum.
Double RID: Use a rosette arrangement with 10ul antiserum in a 3mm diameter center well and 2ul serum samples (neat and serially diluted) in 2mm diameter peripheral wells.
SIngle RID: use 1% antiserum in the gel.
Optimal dilutions to be determined by the researcher.
