- Description
- Description: This 19-3 monoclonal antibody recognizes human and mouse terminal-deoxynucleotidyl transferase (TdT), a 60 kDa polymerase responsible for the template-independent addition of N-nucleotides at gene segment junctions of developing lymphocytes. Expression is found in the nucleus of immature lymphocytes but not in mature lymphocytes or non-lymphoid cells. Tdt plays a critical role during TCR and Ig gene rearrangement. Regulation of expression in the mouse thymus correlates with T cell selection; decreased or absent after positive selection. Additionally Tdt has been shown to be present in lymphoma or lymphoblastic leukemia cells. Applications Reported: This 19-3 antibody has been reported for use in intracellular staining followed by flow cytometric analysis. Applications Tested: This 19-3 antibody has been tested by intracellular staining using the Foxp3/Transcription Factor Staining Buffer Set (Product # 00-5521-00) followed by flow cytometric analysis of mouse thymocytes. This can be used at less than or equal to 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. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser. Filtration: 0.2 µm post-manufacturing filtered.

Offset histograms are representative of at least three independent experiments (total of 6-10 mice/group). ( H, I ) Flow cytometry analysis of CD2 ( H ) and CD25 ( I ) expression. Indicated values are the proportion of Fr. C cells positive for either marker, and quantifications are shown on the right of each plot. Offset histograms are representative of three independent experiments (total of five mice/group). ( J ) Intracellular flow cytometry analysis of TdT expression in Fr. B and Fr. C cells. Indicated values are the proportion of cells positive for TdT expression, and quantifications are shown on the right.
