Flow Cytometry / FACS Antibody | Cancer

Background

Flow cytometry is a method to evaluate cell membrane proteins and intracellular proteins as well as peptides and DNA. The principle behind FACS is an antigen-antibody reaction, with the antibodies being fluorescently labelled. There are three fluorescent proteins (R-PE, APC, and PerCP) conjugated to antibodies. Flow cytometry quantification is carried out with intercalating color labels (without the antibody). Flow cytometry antibodies are widely used in cell counting, cell sorting, biomarker detection andprotein engineering.
Cancer is a class of diseases in which abnormal cells divide without control and are able to invade other tissues. Cancer cells can spread to other parts of the body through the blood and lymph systems. Normally, cell proliferation is under tight control through many mechanisms. Accumulating disruptions in these control mechanisms lead to progressive error accumulation until unregulated proliferation and cancer forming.
