Description: The rat IgG2b, kappa monoclonal antibody is useful as an isotype control immunoglobulin.
Applications Reported: This rat IgG2b, kappa, isotype control has been reported for use as a control for immunofluorescent staining, flow cytometric analysis, immunohistochemistry and immunocytochemistry.
Applications Tested: This rat IgG2b, kappa, isotype control has been tested by immunofluorescent staining and flow cytometric analysis of mouse splenocyte suspensions and can be used at the same concentration as the experimental antibody.
Super Bright 645 is a tandem dye that can be excited with the violet laser line (405 nm) and emits at 645 nm. We recommend using a 660/20 bandpass filter. Please make sure that your instrument is capable of detecting this fluorochrome.
When using two or more Super Bright dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Complete Staining Buffer (Product # SB-4401) to minimize any non-specific polymer interactions. Please refer to the datasheet for Super Bright Staining Buffer for more information.
Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Protect this vial and stained samples from light.
Fixation: Samples can be stored in IC Fixation Buffer (Product # 00-8222) (100 µL of cell sample + 100 µL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically.
Excitation: 405 nm; Emission: 645 nm; Laser: Violet Laser

Rat IgG2b is a protein-coding gene that encodes for the immunoglobulin G2b (IgG2b) subclass of rat antibodies. IgG2b is a major subclass of rat immunoglobulins that plays a crucial role in the immune response by neutralizing pathogens and promoting opsonization. Rat IgG2b is commonly used in research applications, such as in immunohistochemistry, flow cytometry, and Western blotting.
