商品介绍
Product Name | Spike protein (S2) SARS - CoV - 2 substrateQXL®520 - SKPSKRSFIED - K(5 - FAM) - NH2 |
Size | 0.1 mg |
Catalog # | AS-65601 |
US$ | $205 |
Purity | >95% |
This peptide sequence represents a second furin-like cleavage site of the Spike (S) protein also thought to participate in the process of viral entry into host cell. The sequence at the S2 site (KR↓SF) contains two basic residues (P1 and P2) and a hydrophobic P3 residue. This site is identical between the SARS-CoV-2 and SARS-CoV.This peptide has been labeled with QXL®520 and 5-FAM. | |

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。
