Application Notes
|
Western blot: 1:20,000 Recommended Optimum dilutions will vary and should be determined empirically. NOTE: When using PVDF membranes for Western blotting, SDS (final concentration of 0.1 – 0.2%) and Tween? 20 (final concentration of 0.1 – 0.2%) must be added during the detection incubation step to avoid non-specific background staining. IRDye 680LT secondary antibodies are suitable for immunofluorescent microscopy and other fluorescent imaging applications when using instrumentation with appropriate excitation and detection capabilities. IRDye 680LT is not intended for In-Cell WesternTM assays or in vivo applications. These antibodies are not recommended when getting up and running on system. Once established near-infrared protocols are optimized with IRDye 680RD, IRDye 680LT can be used to optimize signals in the 700 channel. Dilution range 1:20,000 – 1:40,000. Note: optimization may be required with IRDye 680LT. Please see pack insert for specific detergents/protocol modifications needed.
