IRDye® 650 Goat anti-Rabbit IgG Secondary Antibody

IRDye 650 Goat anti-Rabbit IgG Secondary Antibody

Immunogen

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 immunofluorescence and flow cytometry applications.

Applications

  • Microscopy
  • Immunohistochemistry
  • Flow Cytometry

Formulation

IRDye 650 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.

Example Data

IRDye 650 example image
Immunofluorescence staining of HER2 protein on SK-BR-3 cells. Cells were cultured on cover slips. After fixation and permeabilization, cells were incubated with rabbit anti-HER2 mAb (CST), followed by detection with IRDye 650 Goat anti-Rabbit (P/N 926-65020). Nuclei were stained with DAPI. Image acquired with Olympus IX81 microscope.
