An In Vitro Method to Determine the Anti-Apoptotic Activity of Antibodies against TNFα

This video demonstrates a technique for assessing the efficacy of antibodies against tumor necrosis factor-alpha (TNFα), an inflammatory cytokine, through an in vitro bioanalytical approach. TNFα, when introduced to stressed cells, triggers apoptosis. However, binding to the antibodies confines TNFα, averting apoptosis. The degree of apoptosis is quantified using a bioluminescence...
