Store product at 4 degree C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20 degree C. Aliquots are stable at -20 degree C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer.

For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Reacts with CD5 antigen (MW 67kD). LT1 completely cross block binding of MAbs Leu 1 and OKT1. Working dilution: 1:5,000. LT1/CD5 is present on the majority of human T-cells. This antigen is also found on the neoplastic cells in all cases of B cell chronic lymphocytic leukaemia, but is not present on normal B cells or on other cell populations.
