IRDye® 800CW Goat anti-Human IgG Secondary Antibody

IRDye 800CW Goat anti-Human IgG Secondary Antibody

Immunogen

Human IgG

Purity and Specificity

Isolation of specific antibodies was accomplished by affinity chromatography using human IgG covalently linked to agarose. Based on ELISA, this antibody reacts with the heavy and light chains of human IgG. This antibody was tested by dot blot and/or solid-phase adsorbed to ensure minimal cross-reactivity with bovine, horse, and mouse serum proteins, but may cross-react with immunoglobulins from other species. The conjugate has been specifically tested and qualified for Western blot applications.

Applications

Highly recommended for:

  • Western Blot
  • In-Cell Western Assay
  • On-Cell Western Assay
  • Protein Array
  • Immunohistochemistry
  • Small Animal Imaging
  • Microscopy
  • 2D Gel Detection
  • Tissue Section Imaging
  • Virus Titration Assay

Formulation

IRDye 800CW secondary antibodies are supplied as purified immunoglobulin conjugates, lyophilized in phosphate-buffered saline, pH 7.4. Protect from light. Store at 4 °C prior to reconstitution.

Each vial contains 10 mg/mL BSA (free of IgG and protease) as a stabilizer and 0.01% sodium azide as a preservative, after reconstitution. Concentration is 1.0 mg/mL when reconstituted as directed. Refer to the pack insert for details on reconstitution.

Optimum dilutions will vary and should be determined empirically.

Example Data

IRDye® 800CW Goat anti-Human IgG Secondary Antibody data
Detection of human IgG with IRDye 800CW Goat anti-Human IgG. Serial dilutions of human IgG were spiked into C32 lysate (Santa Cruz P/N sc-2205). Samples were resolved on a 10% Bis-Tris gel and transferred to Odyssey® Nitrocellulose membrane (P/N 926-31092). Membrane was blocked with Odyssey Blocking Buffer (P/N 927-40000) followed by detection with IRDye 800CW Goat anti-Human IgG (P/N 926-32232).

Selected P/N: 926-32232,925-32232
