FLASH, CT, Blocking Peptide (FLICE-associated Huge Protein), Purified

Peptide (SERFQQLMKLFEKSKC) corresponding to amino acids 1253 to 1268 of human origin, which differ from those of mouse by one amino acid (1,2). A novel mammalian CED-4 homologous was recently identified and cloned in mouse (1) and human (2) and designated FLASH (for FLICE-associated huge protein). FLASH is involved in Fas induced apoptosis. It is recruited to Fas after the receptor cross-linking. Overexpression of wild type of FLASH facilitates and its dominant negative form inhibits Fas induced apoptosis. FLASH interacts with the DEDs of caspase-8 and FADD through the DED-like domain of FLASH and mediates activation of caspase-8 (1). There are parallels between FLASH and Apaf-1/CED-4 although there are arguments against their structural similarity (1,2). FLASH is widely expressed. , Applications: , Suitable for use in ELISA, Western Blotting. Other applications not tested. Positive Control: HeLa whole cell lysate , Storage and Stability:, May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Freeze at -20°C or colder. Aliquots are stable for at least 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
