Biodegradable polymers & microspheres such as PLGA types are receiving high levels of interest for controlled release of active materials in the pharmaceutical industry as growth platforms (e.g. degradable scaffolds for implants and bone grafts) and as prototype materials to measure biodegradation kinetics under specific conditions.
As these sciences expand, there will be a need for controlled particle size biodegradable microspheres for calibration of instrumentation and for particle size assays.
Polysciences Inc. offers two PLGA polymers (75:25 and 50:50 LA/GA ratios) in three narrow particle size ranges; 75, 100 and 120µm, with coefficients of variation less than 10%. Lyophilized to resist biodegradation. These highly uniform particle populations are excellent prototypes for controlled degradation rate measurements “in-vitro” and “in-vivo”.
