IRDye® 680LT Donkey anti-Goat IgG Secondary Antibody

IRDye 680LT Donkey anti-Goat IgG Secondary Antibody


Goat IgG

Purity and Specificity

Isolation of specific antibodies was accomplished by affinity chromatography using goat IgG covalently linked to agarose. Based on ELISA, this antibody reacts with the heavy and light chains of goat IgG and sheep IgG. This antibody has been tested by dot blot and/or solid-phase adsorbed to ensure 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.

Example Data

IRDye® 680LT Donkey anti-Goat IgG Secondary Antibody data
Western blot detection of actin in C32 lysate. C32 lysate (Santa Cruz P/N sc- 2205) was resolved on a 10% Bis-Tris gel and transferred to Odyssey® nitrocellulose (P/N 926-31090). The membrane was probed with goat anti-actin (Santa Cruz P/N sc-1616) followed by detection with IRDye 680LT Donkey anti-Goat IgG (P/N 926-68024).
