F1Aa, Blocking Peptide (FEM1b)

Cat no: F0001-05P

F1Aa, Blocking Peptide (FEM1b)

Peptide (DINYQDQIPRTLEE) corresponding to amino acids 609 to 622 of human F1Aa (1). This sequence is identical to the corresponding sequence of mouse FEM1b (2).\n\nFas and tumor necrosis factor receptor 1 (TNFR1) are two prototype members in the death receptor family. A novel protein that associates with the intracellular domains of Fas and TNFR1 was recently identified and designated F1Aa and FEM1b (1,2). F1Aa/FEM1b is the homologue of C. elegans sex determining protein FEM-1 (1,2). FEM-1/F1Aa is cleaved by CED-3 and caspase (3). FEM-1/F1Aa associates with CED-4 and its mammalian homologue Apaf-1 (3). Overexpression of F1Aa induces apoptosis. F1Aa is therefore a novel member of the death receptor associated protein that mediates apoptosis. F1Aa is expressed in a variety of human and mouse tissues (1,2).\n\nApplications: \nSuitable for use in ELISA, Western Blotting. Other applications not tested.\n\nPositive Control: Mouse liver tissue\n\nStorage and Stability:\nMay be stored at 4 degrees 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 degrees C or colder. Aliquots are stable for at least 6 months at -20 degrees 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.
