Human T cell receptor (TCR) is a T cell surface expressed heterodimer of a/b or g/d chains. TCR's recognize antigen peptides bound to MHC molecules forming the basis of antigen specific response by T cells. Applications: Suitable for use in Flow Cytometry. Other applications not tested. Recommended Dilution: Flow Cytometry: 1:50; 80ul labels 5x10e5 human Jurkat cells. Optimal dilutions to be determined by the researcher. FACS Protocol: 1. Five x 10e5 human Jurkat cells were washed and preincubated 45 minutes with 80ul T2040-04A at 1:50 (10ug/ml). 2. Cells were then washed three times, fixed and analyzed by FACS. 3. Cells stained positive with a mean shift of 0.72 log 10 fluorescent units when compared to a Mouse IgG2a/FITC negative control at a similar concentration. Storage and Stability: May be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
