簡單介紹:
Ac-YVAD-CHO(Caspase-1/ICEInhibitor2-CHO)
詳情介紹:
Purpose Reversible caspase-1, 4 inhibitor?
Sequence Acetyl-Tyr-Val-Ala-Asp-CHO, Ac-YVAD-CHO
Specificity Ac-YVAD-CHO is a reversible inhibitor of caspase-1 and caspase-4 (Ki=200 pM for human recombinant caspase-1). It is more selective than Ac-VAD-CHO for caspase-1. Inhibition of caspases in cell extracts. Ac-YVAD- CHO inhibits anti-Fas induced apoptosis in L929-APO-1 cells. Generally, however, methyl- ated peptide-FMK inhibitors (eg. Caspase-1/ICE Inhibitor 2, Cat No. AB-011) are superior for use on live cells.
Purity > 95 % by HPLC
Formula C23H32N4O8
Solubility Soluble in both DMSO and water.
Molecular Weight 492.5 Da
Comment

Interleukin-1? Converting Enzyme (!CE), also now known as Caspase-1, is a cytoplasmic cysteine protease that cleaves inactive 31 kDa pro-IL-1? to generate the active 17.5 kDa proinflammatory cytokine IL-1?, the predominant form of IL-1 produced by human monocytes. This cytokine has been implicated in the pathogenesis of several diseases such as rheumatoid arthritis, inflammatory bowel disease, and septic shock. Caspase-1/ICE mRNA is found in a variety of cells such as peripheral blood monocytes, peripheral blood lymphocytes, peripheral blood neutrophils, and resting and activated peripheral blood T-lymphocytes. The tissue distribution of Caspase-1/ICE suggests that the enzyme may have other substrates in addition to IL-1?. Current hypotheses suggest that Caspase-1/ICE is able to cause apoptosis as well as activate inflammation in animal cells. Experiments have shown that Caspase-1/ICE has sequence homology with other mammalian apoptosis genes and that activation of Caspase-1/ICE or other caspase proteases is required for anti-Fas mAb-induced apoptosis.

It is recommended that stock solutions be prepared in high-purity DMSO (>99.9%), and then diluted into aqueous medium. Stock solutions should not be stored.
