PEG2000-DMPE is a polyethylene glycol-lipid conjugate combined with phosphatidylethanolamine. PEG2000-DMPE undergoes a conformational transition from mushroom-like to brush-like at a concentration of 7 mol%, thereby exerting multiple functions such as inhibitor, stabilizer and surface defect modifier. PEG2000-DMPE can form a steric hindrance barrier on the vesicle surface to block calcium ion-induced liposome fusion, and dynamically regulate the fusion process through spontaneous transfer rate. PEG2000-DMPE can delay the thinning of foam thin liquid films and smoothly seal surface defects of solid support layers. PEG2000-DMPE can be used in the design and related research of stealth liposomes and micelles .

Prodan is an environment-sensitive fluorescent probe used to investigate the polarity, fluidity, and structure of lipid membranes. Prodan exhibits environment-dependent excitation/emission wavelengths, with its wavelength range covering Ex = 360-410 nm and Em = 430-530 nm when in solvents, bound to DNA, located in lipid bilayers, or associated with proteins. Prodan can interact with the major groove of DNA, regions of lipid bilayers, and hydrophobic pockets of proteins. During phase transitions, Prodan localizes to different regions of the bilayer: the emission minimum is 430-440 nm in the gel phase, while it shifts to 480-500 nm in the liquid-crystalline phase or interdigitated gel phase. When bound to rigid hydrophobic sites of proteins, the emission peak of Prodan undergoes a blue shift and its fluorescence intensity increases .

FITC-PLL is a fluorescently labeled polycationic polypeptide probe composed of polylysine (PLL) and FITC (HY-66019), with a typical Ex/Em of 495/520 nm. The fluorescence intensity and lifetime of FITC-PLL are sensitive to pH and FITC density. FITC-PLL can be used for quantifying hapten receptor binding and endocytosis kinetics in macrophages, as a patternable substrate for neuron guidance, for negatively charged phospholipid membrane binding and transmembrane transport, and for live-cell imaging of starch nanoparticle conjugates and lysosome labeling .

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 .

F6OM, a nonionic fluorinated octyl maltoside derivative, is a surfactant. F6OM readily interacts with and completely solubilizes phospholipid vesicles via a heterogeneous solubilization mechanism, without compromising membrane order at subsolubilizing concentrations. F6OM promotes bilayer insertion of an integral membrane enzyme in the absence of micelles to support functional refolding of integral membrane proteins. F6OM can be used for membrane-protein applications .

NRGolgi is a Nile Red-based solvatochromic fluorescent probe targeted to the Golgi apparatus. NRGolgi localizes selectively to the Golgi membrane via its myristic acid group, and leverages the property of its emission wavelength undergoing blue/red shift with local polarity to quantitatively detect the lipid order of the Golgi membrane in living cells using dual-emission ratiometric imaging (550-600 nm / 600-650 nm). NRGolgi is suitable for real-time monitoring of Golgi lipid order under conditions of oxidative stress, mechanical stress, and altered cholesterol metabolism .
