Bioactivities Of A Tumour Necrosis Like Factor Released By Chicken Rnacrophages, Silke Rautenschlein, Anuradha Subramanian, Jagdev M. Sharma
Bioactivities Of A Tumour Necrosis Like Factor Released By Chicken Rnacrophages, Silke Rautenschlein, Anuradha Subramanian, Jagdev M. Sharma
Papers in Biotechnology
To test for tumour necrosis-like factor (TNF) of chickens, supernatants of a lipopolysaccharide (LPS)-stimulated chicken macrophage cell line MQ-NCSU were analysed. A sequence of ion-exchange and gel-permeation chromatography was utilised to isolate TNF-like activity from the culture supernatant. The peak of TNF-like cytotoxic activity corresponded to the fractions with a nlolecular weight of 81 kDa or higher. Polyclonal anti-human TNF-a antiserum cross-reacted by Western blotting with a 17 kDa protein in the TNF-containing fraction ~ ~ n d e denaturing conditions. This result indicated that chicken TNF-like factor in the biologically active form may be a protein multimer of monomers …
