IRDye 680LT Goat anti-Rabbit IgG Secondary Antibody

IRDye® 680LT Goat anti-Rabbit IgG Secondary Antibody

IRDye 680LT Goat anti-Rabbit IgG Secondary Antibody


Rabbit IgG

Purity and Specificity

Isolation of specific antibodies was accomplished by affinity chromatography using pooled rabbit IgG covalently linked to agarose. Based on ELISA and flow cytometry, this antibody reacts with the heavy and light chains of rabbit IgG, and with the light chains of rabbit IgM and IgA. This antibody was tested by dot blot and and/or solid-phase adsorbed for minimal cross-reactivity with human, mouse, rat, sheep, and chicken 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-Rebbit IgG Secondary Antibody data
Western blot detection of p38 in Jurkat 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 rabbit anti-p38 (Santa Cruz P/N sc-7149) followed by detection with IRDye 680LT Goat anti-Rabbit IgG (P/N 926-68021).

Selected P/N: 926-68021,925-68021
