Polysciences, Inc. PLGA Poly(D,L-lactide-co-glycolide), 50:50, IV 0.4 dl/g, acid-terminated, 10 g | 26780-50-7
Poly(DL-lactide-co-glycolide) (PLGA) is a well-established biodegradable polymer used in medical devices and drug delivery applications. In comparison to poly(L-lactide) (PLLA), PLGA offers control over degradation rate and reduced glass transition temperatures (by increasing glycolide content). The control of these properties makes PLGA especially well-suited for applications where medical devices are only needed for weeks (e.g. drug delivery). Acid-terminated PLGA allows for easy conjugation to drugs with nucleophilic functionalities.SPECIFICATIONSFTIR: conformsINHERENT VISCOSITY (ΗINH): 0.30 - 0.50 dL/g (25°C; CHCl3; 0.5 g/dL)ACID NUMBER: ≥ 3 (mg KOH)/gLACTIDE/GLYCOLIDE : 45-55/45-55 (mol%) (NMR)
Nanocs mPEG-NHS, PEG succinimidyl ester, 1g
Molecualr Weight 5000, N-hydroxylsuccinimide (NHS) functionalized polyethylene glycol (PEG-NHS) is an amino (-NH2) reactive PEG derivative that can be used to modify protein, peptide or any other surfaces with available amino groups. NHS esters react with primary amine groups at pH 7~8.5 to form stable amide bonds. Reaction can be finished in 1 hour. Compare to other NHS ester, succinimidyl carbonate linker provides much higher stability in aqueous solution yet with excellent reactivity.
