Infection Cancer

HA2 peptide is a potent pH-responsive fusion peptide derived from hemagglutinin (HA), corresponding to the N-terminal fusion peptide domain consisting of 23 amino acid residues of HIV-1 gp41 envelope glycoprotein. HA2 peptide adopts a random coil structure under physiological pH conditions; in acidic endosomes, protonation of carboxyl groups reduces negative charge, inducing a transition to an α-helical conformation that can fuse with and destabilize the endosomal membrane. After binding to membranes, the N-terminal and middle regions of HA2 peptide mainly adopt a β-strand conformation, while the C-terminal region remains unstructured. HA2 peptide induces lipid mixing and promotes aqueous content leakage from large unilamellar vesicles whose lipid composition matches that of HIV-1 viruses and target T cells. HA2 peptide is anionic and can bind to cationic peptides to achieve siRNA condensation. HA2 peptide can be used in studies related to cancer and human immunodeficiency virus (HIV) infection .

Synonyms: HOOC-PEG1000-Thiol
HOOC-PEG1000-SH (HOOC-PEG1000-Thiol) is a reactive thiol PEG derivative with a terminal carboxyl group. The carboxyl group can react with amine or hydroxyl groups to form a stable amide bond or an unstable ester bond. The reaction of the carboxyl group allows the amine or hydroxyl group to be converted into a free thiol with a linear PEG linkage. The generated thiol group can be used to modify the surface of gold nanoparticles or participate in other PEGylation reactions. The PEG linkage between the thiol and carboxyl groups has good water solubility, flexible linker distance and higher stability .
