Polyclonal Sheep Highly Purified E
Human complement component 3d (C3d) is a 33kD polypeptide fragment generated over the course of complement activation where complement 3 (C3) convertases cleave C3 to C3b, which is further degraded into iC3b and C3dg/C3d. C3d is involved in the regulation of many aspects of the immune response, including antigen processing and presentation. The C3d/antigen complex mediates B cell activation by simultaneously binding antigen-specific surface bound immunoglobulin and CD21, lowering the complement activation threshold. C3 is crucial in the induction of tolerance generated when an antigen is introduced into immunoprivileged sites and this is exploited by pathogens and cancer cells to evade the immune system by inhibiting complement activation.

PurityPurified by Ion Exchange chromatography.
ImmunogenPurified C3d from pooled activated serum.
SpecificityRecognizes human C3d. Gave a single arc in the alpha region when tested by IEP against aged human plasma (C3d) and a contiuous double arc in the alpha and beta regions when tested against fresh human plasma (C3 and C3d). Identity was confirmed by double diffusion (ouchterlony) vs human plasma and a known
anti-human C3d.
