R-C-4486	Fructan-PEG750-DSPE	MPEG DSPE is a kind of phospholipid peg derivative with terminal DSPE group at PEG end.Fructosan is a polymer of β-d-fructofuran.Fructosyltransferase catalyzed by sucrose and one or more fructose molecules linked into a water-soluble and viscous polymer polysaccharide.	price>
R-M-1992	Propargyl-PEG4-Sulfone-PEG4-t-butyl ester,CAS:2055024-43-4	Propargyl-PEG4-Sulfone-PEG4-t-butyl ester is a PEG linker containing a propargyl group and t-butyl protected carboxyl group acid. The propargyl groups can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield stable triazole linkages. The t-butyl protected carboxyl group (COOH) prevents self coupling or polymerization under standard acid/amine or acid/hydroxyl coupling conditions. The protected acid can be deprotected by acidic or basic hydrolysis. The hydrophilic PEG spacer increases solubility in aqueous media.	price>
