Description

Description: The eBioC1.7 monoclonal antibody reacts with human CD244 (2B4, p38). In human, CD244 is a 38 kDa protein expressed on NK cells, a subset of CD8+ T cells, gammadelta T cells, monocytes, basophils and eosinophils. Binding of the CD244 ligand, CD48, results in NK cell activation, unlike mouse CD244, which is an inhibitory receptor. For CD244 expressed on NK cells, binding of CD48 results in enhanced NK cell cytotoxicity and secretion of IFN-gamma. Recently, it was demonstrated that binding of the C1.7 monoclonal antibody and CD48 involve the same residue in the V domain of human CD244, which explains the ability of C1.7 binding to induce activation of NK cells. Binding of C1.7 to CD244 leads to tyrosine phosphorylation and recruitment of the adaptor molecule SAP (SLAM-associated protein). Patients with X-linked lymphoproliferative disorder (XLPD) have a mutation in SAP which renders it unable to bind to phosphorylated CD244. Applications Reported: This eBioC1.7 antibody has been reported for use in flow cytometric analysis. Applications Tested: This eBioC1.7 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 μg/mL) 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.

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 No. 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. Please protect this vial and stained samples from light. Fixation: Samples can be stored in IC Fixation Buffer (Product No. 00-8222) (100 μL of cell sample + 100 μL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product No. 00-5333) for up to 3 days in the dark at 4 degrees 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 Super Bright Polymer Dyes are sold under license from Becton, Dickinson and Company. Ep-CAM is a ∽40 kD glycoprotein, which functions as an epithelial cell adhesion molecule. Ep-CAM mediates Ca2+-independent homotypic interactions. Formation of Ep-CAM-mediated adhesions has a negative regulatory effect on adhesions mediated by classic cadherins, which may have strong effects on the differentiation and growth of epithelial cells. Ep-CAM overexpression was suggested to be associated with enhanced epithelial proliferation. Ep-CAM is expressed in the majority of human carcinomas and is a marker for tumors of epithelial lineage.
