IRDye® 680LT Donkey Anti-Rabbit IgG

926-68023

Highly Cross-Adsorbed Donkey (Polyclonal) Anti-Rabbit IgG (H+L) Conjugated to IRDye 680LT

Applications

IRDye 680LT secondary antibodies can be used for numerous applications, including Western blotting. IRDye 680LT secondary antibodies are also suitable for immunofluorescent microscopy and other fluorescent imaging applications when using instrumentation with appropriate excitation and detection capabilities. Two-color detection can be achieved by multiplexing IRDye 680LT secondary antibodies with IRDye 800CW secondary antibodies. These antibodies are optimized for use with Odyssey family imagers.

IRDye 680LT is not intended for in vivo applications.

Purity and Specificity

The antibody was isolated by affinity chromatography using antigens coupled to agarose beads. Based on ELISA, this antibody reacts with the heavy and light chains of rabbit IgG and with the light chains common to most rabbit immuno-globulins. This antibody has been tested by ELISA and/or solid-phase adsorbed to ensure minimal cross-reaction with bovine, chicken, goat, guinea pig, hamster, horse, human, mouse, rat, and sheep serum proteins, but the antibody may cross-react with immunoglobulins from other species. The conjugate has been specifically tested and qualified for Western blot applications.

Reconstitute Secondary Antibody

  1. Combine each 0.1 mg of secondary antibody with 0.1 mL of sterile distilled water.

  2. Gently mix by inverting.

  3. Allow the solution to stand at room temperature for at least 30 minutes before use. Protect the solution from light.

    If the solution is not completely dissolved after standing at room temperature, centrifuge the solution.

When stored as recommended, this product is stable for 3 months.

Recommended Dilutions

Optimum dilutions will vary and should be determined empirically.

Avoid non-specific background staining on PVDF membranes: If you are making your own antibody diluent, add SDS (final concentration 0.01 – 0.02%) and Tween® 20 (final concentration 0.2%) to the diluent. If using Intercept® T20 Antibody Diluent, only add SDS (final concentration 0.01 – 0.02%).
