ABSTRACT:
At least two substantially purified tumor necrosis factor (TNF) inhibitors are disclosed which are glycoproteins that are active against TNF. The isolation of 3O kDa and 40 KDa TNF inhibitor from urine is disclosed. The deglycosylated form of the 3O kDa TNF inhibitor and 40 kDa TNF inhibitor are described as being active against TNF. The 40 kDa TNF inhibitor is active against both TNF alpha a TNF beta. The amino acid sequence of the 30 kDa TNF inhibitor and the 40 kDa TNF inhibitor are disclosed. Methods for isolating the TNF inhibitors from human U937 cell medium and producing the proteins by recombinant-DNA methods are also described.
