商品介绍
| Product Name | Elastin, FITC - Conjugated *Water Insoluble* |
| Size | 1 mg |
| Catalog # | AS-85103 |
| US$ | $196 |
Besides water-soluble elastin conjugate (85113), AnaSpec also offers water-insoluble fluoresceinated elastin. This water-insoluble conjugate can also be used for fluorometric measurement of elastase activity. Product 85103 is insoluble bovine neck ligament elastin that is heavily labeled with FITC such that the conjugate"s fluorescence is quenched. Upon digestion by elastase or other proteases, the fluorescence is recovered. Digestion products from the elastin substrate have absorption maxima at ~492 nm and fluorescence emission maxima at ~515 nm. This insoluble elastin derivative is more specific for elastase than 85113. Minimum Purity: 95% | |

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。
