产品描述:Gelatinases are a type of matrix zinc-dependent metalloproteases (MMPs) that degrade gelatins and a variety of other extracellular matrix proteins. These enzymes are synthesized as latent zymogens that are activated by proteolysis and inhibited by tissue inhibitors of metalloproteases (TIMPs). Two mammalian gelatinases, Gelatinase A (MMP-2) and Gelatinase B (MMP-9), are critical for basement membrane degradation and are highly upregulated in variety of tumor cells. Gelatinase activity is usually detected by small peptide-based activity assays which may suffer from lack of substrate specificity. Other methods for gelatinase activity include gelatin Zymography where samples are electrophoresed on a gelatin-containing SDS-PAGE, and further renatured in a suitable buffer for 12-16 h. The zymogram is subsequently stained, and areas of digestion appear as clear bands against a darkly stained background where the substrate has been degraded by the enzyme. Such methods are laborious, time-consuming and may lead to the loss of enzymatic activity as renaturation may not be completely reversible. BioVision’s Gelatinase Activity Assay Kit utilizes a hybrid approach for the detection of gelatinase activity by employing a highly quenched gelatin substrate which upon cleavage by a suitable gelatinase releases a fluorophore, which can be easily quantified using a conventional microplate reader. This method is substrate-specific, simple, fast, high-throughput adaptable and amenable to the sensitive detection of gelatinase activity (as low as 0.06 mCDU for bacterial collagenase) in biological samples.

文献和实验问:我们知道明胶酶谱法可用来测基质金属蛋白酶MMP-2和MMP-9的活性,但不知其他的基质金属蛋白酶活性的测定,比如我要测MMP-1、MMP-3的活性,是否也可用此法测定呢?急切盼复!答:首先应该弄清楚这些基质金属蛋白酶都属于哪一类型,才能考虑下面的问题。你所提到的四种基质金属蛋白酶:MMP-1属胶原酶(Collagenases)MMP-2和MMP-9明胶酶(Gelatinases)MMP-3属基质溶酶(Stromelysins)进行基质金属蛋白酶活性的测定,MMP-1, MMP
明胶酶谱法 原理: Ø 酶谱法的基本过程是先将样品进行SDS-聚丙烯酰胺(SDS-PAGE,含0.1%明胶)电泳分离,然后在有二价金属离子存在的缓冲 系统中使样品中的MMP-2和MMP-9恢复活性,在各自的迁移位置水解凝胶里的明胶,最后用考马斯亮蓝将凝胶染色,再脱色,在 蓝色背景下可出现白色条带,条带的强弱与MMP-2和MMP-9活性成正比。
