Product Code Product Name Mouse anti CD3 Size .2 mg Price (USD) $243 Background UCHT1 is directed against human CD3 the multichain complex associated with the T-cell receptor. Precursor T-cells are surface CD3 negative but positive for cytoplasmic CD3. All mature T-cells are both cytoplasmic and surface CD3 positive. The UCHT1 antibody permits the identification and enumeration of normal and leukemic human blood and bone marrow cells using flow cytometry. Results must be put within the context of other diagnostic tests as well as the clinical history of the patient by a certified professional before final interpretation. Analyses performed with this antibody should be paralleled by positive and negative controls. If unexpected results are obtained which cannot be attributed to differences in laboratory procedures, please contact us. Host Mouse Isotype IgG1 Species Reactivity Human Product Usage The CD3 mAb (clone UCHT1) recognizes cytoplasmic CD3 epsilon in precursor T-cells and cytoplasmic and surface CD3 epsilon in mature T-lymphocytes. The sensitivity of UCHT1 mAb is determined by staining well-defined blood samples from representative donors with serial-fold mAb dilutions to obtain a titration curve that allows relating the mAb concentration to the percentage of stained cells and geometric MFI (mean fluorescence intensity).The sensitivity of UCHT1 mAb is determined by staining well-defined blood samples from representative donors with serial-fold mAb dilutions to obtain a titration curve that allows relating the mAb concentration to the percentage of stained cells and geometric MFI (mean fluorescence intensity).In practice, 50 µl of leukocytes containing 107 cells/ml are stained with 20 µl mAb of various dilutions to obtain a titration curve and to identify the saturation point and detection threshold. The final concentration of the product is then adjusted to be at least 3-fold above the detection threshold. In addition and to control lot-to-lot variation, the given lot is compared and adjusted to fluorescence standards with defined intensity Product Type Primary Antibodies Applications Flow cytometry, Indirect Immunofluorescence Product Formulation Purified by Chromatography, Storage buffer: PBS pH 7.2, 1% BSA, 0.05% NaN3 Storage Conditions Nordic-MUbio monoclonal antibody reagents contain optimal concentrations of affinity-purified antibody. For stability reasons this monoclonal antibody solution contains sodium azide. These reagents should be stored at 2-8
