Lactic acid is a chiral molecule having both (L) and (D) forms with (L) being the common metabolite. The family of lactic acid polymers includes the pure poly-L-lactic acid (PLLA), the pure poly-D-lactic acid (PDLA) and the poly-D,L lactic acid (PDLLA). Many useful compositions occur when the polymer is organized into diblocks or triblocks with poly(ethylene glycol) and/or polycaprolactone.
PEGylated Polylactide (PEG-PLA) is a family of amphiphilic block copolymers are made up of two chemically different homopolymer blocks hydrophilic PEG and hydrophobic PLA. Also, PEG–PLA copolymer nanoparticles are mainly diffusion and degradation controlled release systems.
BOC Sciences offers PEG-PLA copolymers of different PEG and PLA (PLLA, PDLA, PDLLA) molecular weights for use in drug discovery research. In addition, we also offer PEG-PLA copolymers modified with acid, ester, maleimide groups, et al.
