商品介绍
| Product Name | Collagen (Type IV), FAM conjugated |
| Size | 1 mg |
| Catalog # | AS-85112 |
| US$ | $349 |
In this protease substrate, collagen is heavily labeled with a fluorescein derivative, resulting in almost total quenching of the conjugate"s fluorescence. Protease-catalyzed hydrolysis relieves this quenching conjugate, yielding brightly green fluorescent dye-labeled peptides. The increase in fluorescence intensity is directly proportional to protease activity. Collagen, Type IV should be particularly useful in the development of HTS assays for screening Gelatinase A (MMP-2) and Gelatinase A inhibitors, as well as for other gelatinases and collagenases that specifically degrade (Type IV) Collagen. Additionally, lightly fluorescein-labeled collagen may be useful for continuous assays monitored by fluorescence polarization.

品牌介绍
Anaspec阳离子抗菌肽是所有物种先天防御的重要组成部分。在许多生物中，包括真菌，昆虫，两栖动物和人类中，已经鉴定出100多种这些肽。这些疏水性和两亲性肽表现出抗生素，杀真菌，溶血，杀病毒和杀肿瘤活性。基于它们的结构特性，这些抗菌肽可分为三类：螺旋状肽，含有一个至几个二硫键的肽以及富含某些氨基酸（例如脯氨酸或色氨酸）的肽。这些肽大多数具有一些共同的特征，例如它们的低分子量（2-5 kDa），存在多个赖氨酸和精氨酸残基以及两亲性质。尽管尚不清楚它们杀死细菌的确切机制，但已表明导致膜渗透的肽-脂相互作用在其活性中起作用。抗生素肽的实例包括洋甘菊素，其由皮肤的皮肤分泌。非洲爪蟾 ; 人嗜中性粒细胞的防御素和人唾液中的组蛋白。天蚕素是由昆虫在感染条件下产生的。天蚕素A，B和D是紧密的同源物，由天蚕素蛾的35中发现的35-39个残基组成。
