Abstract:
Tumor Necrosis Factor is one of the cell factors with much stronger anti-tumor activity. In this study, photoactive arylazide-4-azidobenzoic acid was modified to Tumor Necrosis Factor-alpha (TNF-alpha). The IR data (2127cm(-1)) was given to confirm the modification. By photo-immobilization, this modified TNF-a was immobilized on cell culture polystyrene. Both the relation between the amount of TNF-alpha in feed and immobilized TNF-alpha and the influence of different UV irradiation time on photo-immobilization are discussed. Microscopic observations of the photo-immobilization TNF-alpha were made by use of scanning electrom microscope and atomic force microscope.
