产品详细信息Description: The UCHL1 monoclonal antibody reacts with human CD45RO, a 180 kDa isoform of CD45. CD45RO is expressed by most thymocytes, activated memory T cells, granulocytes and monocytes. CD22 is a ligand for CD45RO. Expression of CD45RO and CD45RA is used commonly to discriminate subsets of peripheral T cells.Applications Reported: This UCHL1 antibody has been reported for use in flow cytometric analysis.Applications Tested: This UCHL1 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.5 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.APC-eFluor® 780 emits at 780 nm and is excited with the Red laser (633 nm). Please make sure that your instrument is capable of detecting this fluorochome.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 (cat. 00-8222) (100 µL of cell sample + 100 µL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (cat. 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: 633-647 nm; Emission: 780 nm; Laser: Red Laser.Filtration: 0.2 µm post-manufacturing filtered.靶标信息CD45RO (UCHL1, ubiquitin carboxyl terminal esterase L1) is the shortest isoform of a receptor-type protein tyrosine phosphatase, CD45 glycoprotein. CD45 is crucial in lymphocyte development and antigen signaling, serving as an important regulator of Src-family kinases, promotes cell survival by modulating integrin-mediated signal transduction pathway and is also involved in DNA fragmentation during apoptosis. CD45 isoforms differ in their extracellular domains, whereas they share identical transmembrane and cytoplasmic domains. CD45 isoforms differ in their ability to translocate into the glycosphingolipid-enriched membrane domains and their expression depends on cell type and physiological state of the cell. CD45RO is expressed on macrophages, CD8+ T cells, activated T cells and myeloma cells. Besides the role in immunoreceptor signaling, CD45 is important in promoting cell survival by modulating integrin-mediated signal transduction pathway and is also involved in DNA fragmentation during apoptosis.

Cells in the lymphocyte gate were used for analysis. CD45RO Antibody (47-0457-41)Cell research 2017 -Figure 5 PITPNM3 is a CCL18 receptor on naive CD4 + T cells. (A) Representative flow cytometry staining for PITPNM3 and CCR8, potential CCL18 receptors, on gated PB T cell subsets and paired TI naive CD4 + T cells of a breast cancer patient. Cells were gated on CD3 + CD45RA + CD45RO - CD25 - CD4 + /CD8 + for naive CD4 + /CD8 + T cells, CD3 + CD45RA - CD45RO + CD25 - CD4 + /CD8 + for memory CD4 + /CD8 + T cells and CD3 + CD4 + CD25 + for Tregs). Quantitation of PITPNM3 and CCR8 expression on T cell subsets for eight breast cancer patients is provided in Supplementary information, Figure S8A .
