Caspase-1 Fluorometric Assay Kit Detects YVAD-dependent caspase activity, highly-sensitive
Caspase-1 螢光檢測試劑盒 (凋亡蛋白酶1螢光活性分析) YVAD-AFC
半胱氨酸依賴性天冬氨酸定向蛋白酶(Cysteine-dependent aspartate-directed proteases , Caspase)是半胱氨酸蛋白酶家族(cysteine proteases),在細胞凋亡(apoptosis)、壞死(necrosis)和炎症( inflammation)中發揮重要作用。 Caspases 的連續激活在細胞凋亡(cell apoptosis)中發揮重要作用。 Caspase-1,也稱為 IL-1β 轉換酶 (IL-1β-converting enzyme , ICE),是先天免疫的關鍵調節因子。活性 Caspase-1 裂解並激活促炎性 IL-1β 和 IL-18,並促進細胞凋亡(apoptosis)和細胞焦亡(pyroptosis)誘導的炎症形式的細胞死亡。Caspase-1 螢光檢測試劑盒提供了一種方便、簡單的方法來檢測 YVAD 依賴性 caspase 活性。 YVAD-AFC(AFC:7-氨基-4-三氟甲基香豆素)發射藍光(λmax = 400 nm);當YVAD-AFC被Caspase-1或相關的caspase裂解時,游離的AFC會發出黃綠色螢光(λmax = 505 nm),可以使用酶標儀或螢光計進行定量。將凋亡樣品的 AFC 螢光與未誘導的對照進行比較,可確定 Caspase-1 活性的倍數增加。

Cysteine-dependent aspartate-directed proteases (Caspases) are a family of cysteine proteases that play important roles in apoptosis, necrosis, and inflammation. Sequential activation of caspases plays an important role in cell apoptosis. Caspase-1, also known as IL-1β-converting enzyme (ICE), is a key regulator of innate immunity. The active Caspase-1 cleaves and activates pro-inflammatory IL-1β and IL-18, and promotes an inflammatory form of cell death induced by apoptosis and pyroptosis.
Caspase-1 Fluorometric Assay Kit provides a convenient and simple way for detecting the YVAD-dependent caspase activity. YVAD-AFC (AFC:7-amino-4-trifluoromethyl coumarin) emits blue light (λmax = 400 nm); while cleavage of YVAD-AFC by Caspase-1 or related caspases, free AFC emits a yellow-green fluorescence (λmax = 505 nm), which can be quantified by using a microplate reader or a fluorometer. Comparison of the fluorescence of AFC from an apoptotic sample with an uninduced control determines the fold increase in Caspase-1 activity.
Simple one-step procedure; takes 1-2 hours
Fast and convenient
Comparison of the fluorescence of AFC from a treated sample with an untreated control allows determination of the fold increase in caspase-1 activity.
