Opis

General description

Native, human C3d complement component. C3d is formed by the limited digestion of iC3b by trypsin or elastin. The C3d region of C3 contains the portion of the native C3 molecule which is capable of forming a covalent bond attachment to target surfaces under attack by complement. C3d is a polypeptide of M.W. 30 kDa. The binding of C3d to CR2 (CD21) receptors present on B lymphocytes markedly enhances B cell activation initiated by a wide variety of stimuli.

Physical form

In PBS, pH 7.2.

Preparation Note

Following initial thaw, aliquot and freeze (-20°C).

Prepared from serum that has been shown by certified tests to be negative for HBsAg and for antibodies to HIV and HCV.
