产品详细信息Description: The O323 monoclonal antibody reacts with human CD27, a lymphocyte-specific member of the TNFR superfamily. CD27 is expressed by a subset of thymocytes and virtually all mature T cells and is upregulated upon T-cell stimulation. CD27 binds to CD70, and through this interaction, plays an important role in T cell-B cell interaction.Applications Reported: This O323 antibody has been reported for use in flow cytometric analysis.Applications Tested: This O323 antibody hasbeen pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0125 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.eFluor® 450 is an alternative to Pacific Blue®. eFluor® 450 emits at 445 nm and is excited with the Violet laser (405 nm). Please make sure that your instrument is capable of detecting this fluorochome.Excitation: 405 nm; Emission: 445 nm; Laser: Violet Laser.Filtration: 0.2 µm post-manufacturing filtered.靶标信息CD27 is a 50 kDa member of the tumor necrosis factor (TNF) receptor superfamily that includes CD40 and CD30. The TNF superfamily members are known for the regulation of cell proliferation and death. In contrast to the expression of other TNFR/TNF family members, expression of CD27 and its ligand CD70 is predominantly confined to lymphocytes. High expression levels of CD27 appear to be dependent on proper ligation of antigen receptors. CD70 expression requires additional co-stimulatory and/or pro-inflammatory signals. CD27 is expressed as a disulfide-linked homodimer on mature thymocytes, peripheral blood T cells and a subpopulation of B cells. Activation of T cells via TCR-CD3 complex results in upregulation of CD27 expression on the plasma membrane as well as in the release of its soluble 28-32 kDa form, sCD27, detected in the plasma, urine or spinal fluid. Soluble CD27 is an important prognostic marker of acute and chronic B cell malignancies. RgpA, a cystein proteinase, although activating T cells through the protease-activated receptors (PARs), degradates CD27 and counteracts T cell activation mediated by CD27 and its ligand CD70. CD27-binding protein (SIVA), a proapoptotic protein, can bind to this receptor and is thought to play an important role in the apoptosis induced by this receptor. Diseases associated with CD27 dysfunction include Lymphoproliferative Syndrome 2 and Autosomal Recessive Lymphoproliferative Syndrome.
