introduction: daphne species has both pharmaceutical applications and anti tumor activity. it has been shown that the extract of daphne mucronata is effective in decreasing the size of breast adenocarcinoma in rats. we investigated the mechanism of action and the effects of the extract on tnf-a and tnf-a receptors on cultured human monocytes. material and methods: the breast tumors were induced...

Tumor necrosis factor alpha (TNF-α) is an inflammatory cytokine which plays crucial roles in pathogenesis of inflammatory diseases. The current study aimed to investigate the binding abilities of I44 and I49 domain antibodies to TNF-α. The dAbs were expressed in bacterial expression system and purified by affinity chromatography using Ni-sepharose column. The expression and purity of the protei...
