Analysis of neutralizing activity in vivo of recombinant monoclonal antibody against tumor necrosis factor-α from human origin by using mouse model of liver necrosis
Objective To establish a mouse model of liver necrosis and analyze the neutralizing activity in vivo of recombinant monoclonal antibody(Mc Ab)against tumor necrosis factor(TNF)-α from human origin. Methods The time for sensitization with D-galactosamine(D-Gal N)and lethal dose of TNF-α to C57 BL / 6 mice were determined. Mice were sensitized with D-Gal N and injected i. p. with TNF-α to establish liver necrosis model, with which the neutralizing activities in vivo of three batches of test samples(Mc Ab agai...
