Ths is a HiLyte Fluor labeled HIV protease substrate I, GABA-Ser-Gln-Asn-Tyr-Pro-Ile-Val-Gln-EDANS. The peptide sequence is derived from the native p17/p24 cleavage site on HIV precursor polyprotein Prgag for HIV-1 protease. Cleavage of HIV precursor polyproteins is essential for the maturation of the infectious virus and hence the protease has become a major target for developing anti-AIDS drugs. The peptide substrate is widely used for the continuous assay for HIV protease activity. The QXL/488 pair offers better sensitivity in detection at a higher wavelength with less background interference. (Excitation/Emission = 490 nm/520 nm). | |

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。
