VRDye 490 Donkey anti-Goat Secondary for Western Blotting


Goat IgG

Purity and Specificity

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