IRDye® 680LT Goat anti-Rat IgG Secondary Antibody

IRDye 680LT Goat anti-Rat IgG Secondary Antibody

Immunogen

Rat IgG, whole molecule

Purity and Specificity

The antibody was purified from antisera by immunoaffinity chromatography using antigens coupled to agarose beads. Based on immunoelectrophoresis and/or ELISA, this antibody reacts with whole molecule rat IgG, and with the light chains of other rat immunoglobulins. No reactivity was detected against non-immunoglobulin serum proteins. This antibody has been tested by ELISA and and/or solid-phase adsorbed to ensure minimal cross-reactivity with mouse, bovine, horse, human, and rabbit 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 Goat anti-Rat IgG Secondary Antibody data
Western blot detection of tubulin in C32 lysate. Samples loaded in 4X Protein Sample Loading Buffer (P/N 928-40004), resolved on a 10% Bis-Tris gel, and transferred to Odyssey® nitrocellulose (P/N 926-31090). The membrane was blocked with Odyssey Blocking Buffer (P/N 927-40000) and probed with rat anti-tubulin (Novus Biologicals P/N NB600-506) followed by detection with IRDye 680LT Goat anti-Rat IgG (P/N 926-68029).

Selected P/N: 926-68029,925-68029
