使用适用于进行显微镜检查(包括荧光显微镜检查和高内涵筛选 (HCS))的 Image-iT LIVE 红色和绿色多聚半胱天冬酶以及半胱天冬酶-3 和半胱天冬酶-7 细胞凋亡检测试剂盒检测和评估半胱天冬酶活化、膜可透过性和细胞周期。Image-iT LIVE 红色和绿色半胱天冬酶检测试剂盒使用荧光半胱天冬酶抑制剂 (FLICA) 方法检测和报告半胱天冬酶活性,这是衡量细胞凋亡的指标。具体而言,Image-iT LIVE 红色和绿色半胱天冬酶检测试剂盒分别包含底物 SR-VAD-FMK 和 SR-DEVD-FMK(用于红色荧光)或 FAM-VAD-FMK 和 FAM-DEVD-FMK(绿色荧光),分别用于进行多聚半胱天冬酶和半胱天冬酶-3/7 检测。它们还包括 Hoechst 33342 和碘化丙啶染色剂,能够通过显微镜检查和 HCS 同时评估膜可透过性和细胞周期。
用于显微镜检查的 Image-iT LIVE 红色和绿色半胱天冬酶检测试剂盒采用了一种检测活性半胱天冬酶的新方法:这两种试剂盒均利用荧光半胱天冬酶抑制剂 (FLICA) 方法(亲和标记)。该试剂将一个可以与半胱氨酸发生共价反应的氟甲基酮 (FMK) 部分和一个半胱天冬酶特异性氨基酸序列相连接。不同的氨基酸识别序列用于检测不同的半胱天冬酶:缬氨酸-丙氨酸-天冬氨酸 (VAD) 用于检测多聚半胱天冬酶(包括半胱天冬酶-1、-3、-4、-5、-6、-7、-8 和 -9),天冬氨酸-谷氨酸-缬氨酸-天冬氨酸 (DEVD) 用于检测半胱天冬酶-3/7。连有一个磺酰罗丹明 (SR) 基团或羧基荧光素 (FAM) 基团,作为报告基团。

FLICA 试剂与已激活半胱天冬酶的反应中心通过识别序列相互作用,之后通过 FMK 基团与半胱氨酸共价连接。FLICA 抑制剂具有细胞渗透性但没有细胞毒性。未结合的 FLICA 分子扩散出细胞并被洗涤掉,其余的红色或绿色荧光信号可用于直接测定加入抑制剂时存在的活性半胱天冬酶的量。FLICA、碘化丙啶和 Hoechst 33342 试剂的近似激发峰和发射峰分别为 488⁄ nm/530 nm、535⁄ nm/6617 nm 和 350 nm/⁄461 nm。Image-iT LIVE 红色多聚半胱天冬酶、红色半胱天冬酶-3/7 绿色、绿色多聚半胱天冬酶和绿色半胱天冬酶-3/7 检测试剂盒中包括的检测试剂分别为 SR-VAD-FMK、SR-DEVD-FMK、FAM-VAD-FMK 和 FAM-DEVD-FMK。

Abstract
Multiparametric evaluation of apoptosis: effects of standard cytotoxic agents and the cyanoguanidine CHS 828.
Authors:Lövborg H, Nygren P, Larsson R
Journal:Mol Cancer Ther
PubMed ID:15141009
'A multiparametric high-content screening assay for measurement of apoptosis was developed. HeLa cells and lymphoma U-937 cells were exposed to cytotoxic drugs in flat-bottomed optical microtiter plates. After incubation, the DNA-binding dye Hoechst 33342, fluorescein-tagged probes that covalently bind active caspases and chloromethyl-X-rosamine to detect mitochondrial membrane potential (MMP) were ... More
MiR-351 transiently increases during muscle regeneration and promotes progenitor cell proliferation and survival upon differentiation.

Journal:Physiol Genomics
PubMed ID:22968638
MicroRNAs (miRNAs) regulate many biological processes including muscle development. However, little is known regarding miRNA regulation of muscle regeneration. Murine tibialis anterior muscle was evaluated after cardiotoxin-induced injury and used for global miRNA expression analysis. From day 1 through day 21 following injury, 298 miRNAs were significantly changed at least ... More
Streptococcus pneumoniae evades human dendritic cell surveillance by pneumolysin expression.

Dendritic cells (DCs) protect the respiratory epithelium via induction of innate immune responses and priming of naïve T cells during the initiation of adaptive immunity. Streptococcus pneumoniae, a commonly carried asymptomatic member of the human nasopharyngeal microflora, can cause invasive and inflammatory diseases and the cholesterol-dependent cytotoxin pneumolysin is a ... More

Journal:Integr Cancer Ther
PubMed ID:19679626
Head and neck squamous cell carcinomas (HNSCCs) are known for their aggressive growth and propensity to metastasize. The authors investigated the effect of a novel nutrient mixture (NM) containing ascorbic acid, lysine, proline, and green tea extract on human HNSCC cell line FaDu in vivo and in vitro.
