Cell Technology’s APO 3/7 HTS Assay utilizes the quenched (z-DEVD)2-R110 peptide substrate for caspase 3/7 detection. The absorption and emission properties of the R110 dye are suppressed when attached to the z-DEVD peptide sequence. When R110 is cleaved away, by active caspase3/7, form the quenching DEVD sequence, the free dye excites at 488nm and emits at 515-530 nm. As a result of a novel and proprietary Lysis Buffer System, the APO 3/7 HTS Assay is a homogenous platform that can be utilized for high throughput fluorescence plate reader applications. The reagent is directly added to the samples thus eliminating any wash steps.
Figure. In this figure, Jurkat cells were stimulated with various concentrations of staurosporine for 3 hours, after which caspase 3/7 activity was analyzed using the APO 3/7 HTS kit.

请教各位大神,我最近在做WB,565KD的蛋白,动物组织的样品,听说样品制备需要蔗糖裂解液,请问这个是必须的嘛?用一般蛋白提取方法制备可以吗?还有电泳和转膜条件能否分享一下。不胜感激
脂质的生物学功能有1、脂肪氧化分解释放能量
2、复合脂质和衍生脂质是构成细胞的成分
3、促进脂性维生素的吸收
4、脂肪防震和隔热保温作用
5、脂肪的氧化利用具有降低蛋白质和糖消耗的作用

脂质(Lipids)又称脂类,是脂肪及类脂的总称.这是一类不溶于水而易溶于脂肪溶剂(醇、醚、氯仿、苯)等非极性有机溶剂。并能为机体利用的重要有机化合物。脂质包括的范围广泛,其分类方法亦有多种。通常根据脂质的主要组成成分分为:简单脂质、复合脂质、衍生脂质、不皂化脂类。
基本介绍
不溶于水而能被乙醚、氯仿、苯等非极性有机溶剂抽提出的化合物,统称脂类。
脂类包括油脂(甘油三酯)和类脂(磷脂、蜡、萜类、甾类)。
脂类是机体内的一类有机小分子物质,它包括范围很广,其化学结构有很大差异,生理功能各不相同,其共同物理性质是不溶于水而溶于有机溶剂,在水中可相互聚集形成内部疏水的聚集体(如右图)。
脂类是油、脂肪、类脂的总称。食物中的油脂主要是油和脂肪,一般把常温下是液体的称作油,而把常温下是固体的称作脂肪.
固醇(sterol) 又称甾醇。类固醇的一种。固醇类化合物广泛分布于生物界。用碱性溶液提取动植物组织中的脂类,其中常有多少不等的、不能为碱所皂化的物质,它们均以环戊烷多氢菲为基本结构,并含有醇基,故称为固醇类化合物。胆固醇是高等动物细胞的重要组分。它与长链脂肪酸形成的胆固醇酯是血浆脂蛋白及细胞膜的重要组分。植物细胞膜则含有其它固醇如豆固醇及谷固醇。真菌和酵母则含有菌固醇。胆固醇是动物组织中其它固醇类化合物如胆汁醇、性激素、肾上腺皮质激素、维生素D3等的前体。
westblot蛋白免疫印迹实验跑小分子蛋白(15kd)条带一直是波浪状,有人说是胶的问题,可同时跑了36kd蛋白,条带是直的,有人说是要恒流跑,电压不要太大,我的转膜条件是50v,50min,请教各位大神指点,万分感谢!!!
