Caspase 12, IN, Blocking Peptide

Peptide (CTPSSPSESKRKVEDDE) corresponding to aa100-116 of murine caspase-12(3).||Three distinct signaling pathways lead to programmed cell death (apoptosis). The death receptor and mitochondrion pathways are the mains, in which the key apoptotic proteases capase-8 and caspase-9, respectively, are involved. The endoplasmic reticulum (ER) stress is the third apoptotic pathway and caspase-12 is involved (1,2). Caspase-12 is localized to the ER but not to cytoplasm or mitochondrion. Caspase-12 is activated by ER stress, including disruption of ER calcium homeostasis, and mediates ER stress-induced apoptosis. Caspase-12 is colocalized to the ER with several proteins that are involved in Alzheimer’s disease including g-secretase presenilin and b-amyloid precursor protein (APP). Caspase-12 mediates cytotoxicity induced by amyloid-b. Caspase-12 is ubiquitously expressed in mouse tissues (1).||Applications: Suitable for use in ELISA and Western Blot. Other applications not tested.||Storage and Stability: Lyophilized powder may be stored at -20°C. Reconstitute to nominal volume by adding sterile 25% glycerol and store at -20°C. May be stored at 4°C for short-term only. Reconstituted product is stable for 12 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.
