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 .

GALA-chol is a cholesterol-conjugated pH-responsive fusion peptide that can serve as a delivery adjuvant. GALA-chol enhances the endocytosis of siRNA RET/PTC1-SQ nanoparticles, inhibits cell viability, and undergoes pH-responsive charge conversion in the acidic lysosomal environment, thereby promoting lysosomal escape of small extracellular vesicle (sEV) cargo. GALA-chol anchors to the sEV membrane and maintains the structural integrity and intrinsic homing activity of sEVs. GALA-chol can be used in studies related to adjuvant delivery .

AF633 C5 Maleimide is a fluorescent dye used for surface protein labeling of extracellular vesicles and peptide labeling. AF633 C5 Maleimide covalently binds to protein thiol residues under neutral pH conditions (6.5-7.5), enabling visualization and quantitative analysis of extracellular vesicle uptake by target cells. AF633 C5 Maleimide undergoes maleimide-cysteine conjugation with cysteine residues on peptides in acetonitrile-water buffer solution, supporting detection of peptide-functionalized gold nanorods via confocal laser scanning microscopy, as well as tracking their cellular uptake and localization .

SGC5 is a fluorescence enhancer and membrane dissociator with millisecond-scale membrane dissociation kinetics, with an emission spectrum of 500-650 nm. SGC5 produces strong fluorescence upon binding to lipid membranes, exhibits fast partitioning dissociation kinetics at higher temperatures, and is unaffected by pH or cholesterol. SGC5 does not belong to the FM dye family and shows the highest membrane-bound fluorescence intensity among the tested styryl/FM dyes. SGC5 can be used to study synaptic vesicle cycling in neurons .

Mem-pH is a ratiometric fluorescent probe used for measuring vesicular pH. Mem-pH inserts into the plasma membrane bilayer and localizes to the vesicular lumen, switching between its basic and acidic forms via protonation during vesicular acidification to enable ratiometric pH readout. In aqueous media, Mem-pH forms non-emissive aggregates through aggregation-induced quenching, and then depolymerizes and recovers its fluorescent activity upon binding to the plasma membrane. The excitation/emission wavelengths of the basic form of Mem-pH are 405/450-550 nm, while those of the acidic form are 488/500-700 nm .
