DNA fragments encoded full-length cytokine EMAP-2 and cytokine-like domain of mammalian TyrRS and truncated from COOH- and NH2-termini forms were cloned in vector for bacterial expression pET32a. For all clones bacterial overexpression were obtained and full-length forms were purified to homogeneity state by affin chromatography and affinity tag was remove by protease cleavage. Induction of tissue factor for full-length forms was tested. Full-length form of cytokine-like domain of mammalian TyrRS did not interact with polyclonal antibody against EMAP-2 in western-blot analysis. It was concluded that this set of recombinant proteins may be usefull for functional study of these cytokine proteins.References
