Stability of human lymphocyte differentiation antigens when stored at room temperature

The development of monoclonal antibodies to human differentiation antigens and cytofluorographs have added a new dimension to immune monitoring. However, the technology is such that regionalization will most likely occur. We have demonstrated that human lymphocyte antigens OKT3, OKT4, OKT8 and OKT11 are stable in blood samples stored in ACD at room temperature for less than 72 h. This will allow samples to be analyzed in regional centers.
