This paper describes a defined serum-free medium (SFM), designated A-X, which supports in vitro proliferation of human primary T cells stimulated with mitogens, two-way mixed leukocyte reactions, anti-CD3, and a superantigen. A-X is a 1:1 mixture of two commercially available SFM, AIM V and EX-CELL 300. In each assay tested it supported uptake of [3H]thymidine as well as or better than the standard culture medium, namely RPMI 1640 supplemented with 10% fetal calf serum. A-X also allowed the detection of interleukin-2 by ELISA at levels comparable to those produced in serum-supplemented medium. A-X will likely be useful in further studies as it eliminates many of the problems usually associated with the use of serum-supplemented media.
