商品介绍
Product Name | MMP Colorimetric Substrate IAc - PLG - SCH[CH2CH(CH3)2] - CO - LG - OC2H5 |
Size | 1 mg |
Catalog # | AS-27096 |
US$ | $125 |
Purity | % Peak Area By HPLC ≥ 95% |
An exceptional MMP-2 (gelatinase A) and MMP-9 (gelatinase B) substrate this peptide is used for the continuous spectrophotometric assay of MMP-2 and MMP-9 in combination with a color-developing thiol-reactive agent, 4,4-dithiodipyridine or Ellmans Reagent (as indicators). This thiol peptide-enzyme reaction has a Km of 0.004 M and a kcat of 103 s-1. Using this substrate, collagenase can be detected at concentrations as low as 2 ng/mL. HPLC and tandem mass spectrometry are also used to analyze MMP-2 and MMP-9 in conjunction with this peptide substrate. | |

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。
