Product Name：Octaarginine

Synonyms：八聚精氨酸

CAS No.：148796-86-5

Catalog No.：GT-XL0127

Brand：Go Top peptide（杭州固拓）

Description：Octaarginine由8个精氨酸组成，是目前研究最广泛、穿透效率最高的细胞穿透肽之一，pH7.0时携带约+8电荷，能与带负电的细胞膜强烈相互作用；guanidinium基团精氨酸侧链的胍基与细胞膜磷脂和硫酸酯形成氢键，促进直接穿透。

Octaarginine is composed of 8 arginine residues and is one of the most extensively studied and efficient cell-penetrating peptides. At pH 7.0, it carries about 8 charges and can strongly interact with negatively charged cell membranes; the guanidinium group on the arginine side chain forms hydrogen bonds with membrane phospholipids and sulfates, facilitating direct penetration.
