**Background of DFFA Antibody**
The DFFA (DNA Fragmentation Factor Subunit Alpha) antibody is a critical tool for studying apoptosis, a programmed cell death process essential for maintaining tissue homeostasis. DFFA, also known as ICAD (Inhibitor of Caspase-Activated DNase), is a 45 kDa protein that forms a complex with DFFB (DFF Subunit Beta, or CAD). This heterodimer regulates DNA fragmentation, a hallmark of apoptosis. In healthy cells, DFFA inhibits the nuclease activity of DFFB. Upon apoptosis induction, caspases cleave DFFA, releasing DFFB to degrade chromosomal DNA into nucleosomal fragments.
Antibodies targeting DFFA are widely used in research to detect and quantify the protein’s expression, cleavage, or localization in cells and tissues. They enable techniques like Western blotting, immunofluorescence, and immunohistochemistry, helping to assess apoptosis activation in cancer, neurodegenerative diseases, or developmental studies. Specific DFFA antibodies may recognize full-length or cleaved forms, aiding in distinguishing inactive versus apoptosis-activated states.
Studies using DFFA antibodies have elucidated its role beyond apoptosis, including potential involvement in DNA repair and cell cycle regulation. Dysregulation of DFFA/DFFB is linked to diseases like cancer, where defective apoptosis contributes to tumor progression. Thus, DFFA antibodies serve as vital reagents for both basic research and translational studies aimed at understanding cell death mechanisms and developing therapeutic strategies.
