Cat. No.: HY-142978
CAS No.: 156543-00-9
Synonyms: DSPE-mPEG2000
18:0 mPEG2000 PE (DSPE-mPEG2000) ammonium is a kind of amphiphilic polymer material. 18:0 mPEG2000 PE ammonium combines hydrophobic lipids (18:0 stearic acid chain) with hydrophilic polyethylene glycol (2 kDa) chains to form amphiphilic molecules, which are used to construct stable liposomes/nanoparticles, thereby enhancing drug delivery, prolonging circulation time, and achieving targeted effects through its functional terminal groups (usually biotin or carboxyl groups). 18:0 mPEG2000 PE ammonium can be used for the research of nanoprobes and drug delivery .

Synonyms: mPEG2000-COOH
mPEG2000-CM (mPEG2000-COOH) is a carboxyl-terminated monomethoxy polyethylene glycol. mPEG2000-CM bears a reactive carboxyl group (-COOH) at its structural terminal site, which can form stable amide bonds with amino groups and ester bonds with hydroxyl groups. mPEG2000-CM binds to PCA-g-PCL copolymers via electrostatic interaction to form polyion complex micelles with a hydrophilic PEG surface, which enhances the stability of micelles in aqueous media. mPEG2000-CM can be used for drug delivery .

DABCYL-LPETG-EDANS is a biological active peptide. (This 5-amino acid peptide is a sortase substrate, C-terminal sorting signal. Sortase cleaves surface proteins at the LPXTG motif and catalyzes the formation of an amide bond between the carboxyl group of threonine and the amino group of cell-wall crossbridges. Sortases are a family of Gram-positive transpeptidases responsible for anchoring surface protein virulence factors to the peptidoglycan cell wall layer. Cleavage of this FRET substrate by sortase reveals the fluorescent signal, Abs/Em = 340/490 nm.)
