Highly cross-adsorbed donkey anti-rabbit IgG (H+L) antibody conjugated to VRDye 490.

Immunogen

Purity and Specificity

The antibody was isolated by affinity chromatography using antigens coupled to agarose beads. Based on ELISA, this antibody reacts with heavy and light chains of rabbit IgG and light chains common to most rabbit immunoglobulins. This antibody has been tested by ELISA and/or solid phase adsorbed to ensure minimal cross-reaction with bovine, chicken, goat, guinea pig, hamster, horse, human, mouse, rat, and sheep serum proteins but may cross-react with immunoglobulins from other species. The conjugate has been specifically tested and qualified for Western blot applications.

Applications
