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

Isolation of specific antibodies was accomplished by immunoaffinity chromatography using antigens immobilized on agarose beads. Based on immunoelectrophoresis and/or ELISA, this antibody reacts with whole molecule guinea pig IgG as well as the light chains common to other guinea pig immunoglobulins. No reactivity was detected against non-immunoglobulin serum proteins. This antibody was tested by ELISA and/or solid-phase adsorbed for minimal cross-reactivity with bovine, chicken, goat, Syrian hamster, horse, human, mouse, rabbit, rat, and sheep serum proteins, but may cross-react with immunoglobulins from other species. The conjugate has been specifically tested and qualified for Western blot applications.

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%).
