PRODUCT DETAILS Host: Mouse Isotype: IgG1, kappa Clonality: Monoclonal Clone: CD28.2 Format: Brilliant Violet 650 Reactivity: Hu Application: Flow Cytometry Tested Dilution: 5 µL (1.0 µg)/test Concentration: 5 μL/Test Storage: 4°C, store in dark, DO NOT FREEZE! Formulation: PBS with BSA and 0.09% sodium azide; pH 7.2 Purification: Affinity chromatography Data Sheet: TDS Specific Information Description: The CD28.2 monoclonal antibody reacts with the human CD28 molecule, a 44 kDa homodimer expressed by thymocytes, mature T cells and plasma cells. CD28 is a ligand for CD80 (B7-1) and CD86 (B7-2) and is a potent co-stimulator of T cells. Signaling through CD28 augments IL-2 and IL-2 receptor expression as well as cytotoxicity of CD3-activated T cells. Applications Reported: This CD28.2 antibody has been reported for use in flow cytometric analysis. Applications Tested: This CD28.2 antibody has been pre-diluted and tested by flow cytometric analysis of normal human peripheral blood cells. This may be used at 5 µL (1.0 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Brilliant Violet™ 650 (BV650) is a tandem dye that emits at 649 nm and is intended for use on cytometers equipped with a violet (405 nm) laser. Please make sure that your instrument is capable of detecting this fluorochrome. When using two or more Super Bright, Brilliant Violet™, Brilliant Ultra Violet™, or other polymer dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Complete Staining Buffer (Product # SB-4401-42) or Brilliant Stain Buffer™ (Product # 00-4409-75) to minimize any non-specific polymer interactions. Please refer to the datasheet for Super Bright Staining Buffer or Brilliant Stain Buffer for more information. Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Please protect this vial and stained samples from light. Fixation: Samples can be stored in IC Fixation Buffer (Product # 00-8222-49) (100 µL of cell sample 100 µL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 00-5333-54) 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. Our internal testing suggests that Brilliant Violet™ 650 (BV650) is not compatible with methanol-based fixation. Excitation: 407 nm; Emission: 649 nm; Laser: Violet Laser.
