CD185 (CXCR5) Monoclonal Antibody (SPRCL5), Brilliant Ultra Violet™ 615, eBioscience™, Invitrogen™

Description

• CD185 (CXCR5) Monoclonal antibody specifically detects CD185 (CXCR5) in Mouse samples
• It is validated for Flow Cytometry Description: This SPRCL5 monoclonal antibody reacts with Mouse CD185
• CD185, which is also known as C-X-C chemokine receptor 5 (CXCR5) and Burkitt lymphoma receptor 1 (BLR1), is a seven transmembrane G protein-coupled receptor originally identified in Burkitt's lymphoma
• In peripheral blood, CXCR5 is expressed on B cells, CD4+ T cells (but not Th1 or Th2 cells), as well as on a subpopulation of memory (CD45RO+) T cells
• CXCR5+ circulating T cells are in a resting state and migrate to the lymph nodes due to expression of CCR7 and CD62L
• In tonsil, CXCR5 is expressed on nearly all CD4+ cells along with CD45RO and such activation markers as CD69 and ICOS
• Tonsillar CXCR5+ cells have been shown to induce antibody production when co-cultured with B cells, thus supporting their role in providing B cell help
• Furthermore, this chemokine receptor plays a critical role in lymphocyte trafficking, in particular T cell migration into the B cell follicles of germinal centers in response to CXCL13, making CXCR5 an established marker of follicular helper T cells
• This SPRCL5 does not see a formaldehyde fixed epitope, therefore staining should be done prior to fixation
• Applications Reported: This SPRCL5 antibody has been reported for use in flow cytometric analysis
• Applications Tested: This SPRCL5 antibody has been tested by flow cytometric analysis of mouse splenocytes
• This may be used at less than or equal to 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
• It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest
• Brilliant Ultra Violet™ 615 (BUV615) is a tandem dye that emits at 615 nm and is intended for use on cytometers equipped with an μgtraviolet (355 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
• Excitation: 350 nm; Emission: 615 nm; Laser: Ultraviolet Laser
