ApoptosisInduction
IntroductionWhen studying induction of apoptosis via a cell surface molecule, it is important to first ascertain surface expression of the molecule of interest. This can be achieved by performing flow cytometry or immunoprecipitation/Western blotting assays. Another factor important in achieving optimal results is the degree of sensitivity of cells to the antibody-induced apoptosis. As an example, CD95 (Fas)-ind......阅读全文
