title: Bovine interleukin 2: cloning, high level expression, and purification.
abstract: We utilized a human IL2 probe to isolate bovine IL2 sequences from a lymph node cDNA library. Bovine IL2 was subsequently expressed in both bacteria and yeast. Using a rapid, two-step purification scheme, we have been able to isolate over 20 mg/l of homogenous bovine rIL2 secreted from the yeast. The availability of sizable quantities of bovine rIL2 should make it possible to ascertain potential therapeutic or prophylactic utility of this lymphokine in cattle.
