tat (4857)

TAT (48-57) 是一种富含精氨酸的经典细胞穿透肽 (CPP)，其序列源自 HIV-1 TAT 蛋白。它具有极强的非受体依赖性膜通透能力，能高效介导各类大分子载荷（如蛋白质、核酸或纳米药物）跨过细胞膜进入胞质。

TAT (48-57) (TFA) is a cellular permeability peptide derived from hiv-1 transcriptional activator (TAT) protein residue 48-57.

TAT (48-57) acetate is a cell-permeable peptide derived from the HIV-1 transactivator of transcription (Tat) protein, encompassing amino acid residues 48 to 57 from the basic domain of HIV Tat.
