Contamination of commercial leukocyte-derived human interleukin 2 with interleukin 1
Lymphokine Research
|January 1, 1985
Commercial preparations of human leukocyte-derived IL-2 were tested for the presence of contaminating IL-1 by affinity chromatography. Two samples from Electro-Nucleonics were found to contain significant amounts of IL-1, suggesting that IL-1 may contaminate preparations of leukocyte-derived IL-2.
