Purification: Recombinant soluble human Fas was expressed in the Baculovirus Expression Vector System and purified from insect cell lysate using an anti-Fas antibody. This form of Fas lacks the transmembrane domain of the Fas receptor, and has been referred to as FasΔTM. It has a 63-base pair deletion starting at nucleotide sequence (700) GA TCC AGA and ending at nucleotide sequence GTT TGG G (762). The purity and the integrity of the protein were verified by SDS-PAGE, and ELISA. FasΔTM has a reduced molecular weight of ~40 kDa.

Application Details

Application Notes: Purified FasDeltaTM can be used as a positive control for western blot analysis of Fas. 1 µg of protein can easily be visualized on a Commasie-stained gel as a band of ~40 kDa. For western blot analysis, 1 µg or less is sufficient depending on the detection method (less is needed for enhanced chemiluminescence than for standard alkaline phosphatase detection). Purified FasDeltaTM can also be used as a standard in Fas ELISA assays. The recombinant FasDeltaTM protein should not be used in functional assays, as it does not appear to assume a biologically active conformation.

Handling

Format: Liquid

Handling Advice: Fas (APO-1, CD95) is an ~42 kDa cell surface protein that mediates apoptosis when cross-linked with agonistic anti-Fas antibodies or Fas ligand (FasL). Fas belongs to the TNF (tumor necrosis factor)/NGF (nerve growth factor) receptor family, and is expressed in various tissue and cells including the thymus, liver, ovary and lung. FasL is a 40 kDa TNF family member membrane protein that induces apoptosis by binding to Fas, its cell-surface receptor. FasL is expressed on activated T and NK cells. Both Fas and FasL are thought to play an important role in the apoptotic processes that take place during T cell development.

Storage: -20 °C,-80 °C

Storage Comment: Avoid multiple freeze-thaws of product. Store the protein at -20°C, or for longer storage life, at -80°C.
