4-Arm PLGA-Biotin is a star-shaped biodegradable polymer composed of four PLGA chains capped with biotin moieties. In contrast to linear PLGA-Biotin, it delivers higher functional group density, superior conjugation efficiency and better drug loading performance with tunable polymer architecture. Terminal biotin groups support high-affinity interaction with avidin and streptavidin, rendering this material suitable for targeted drug delivery, nanoparticle modification, bioseparation, diagnostic platforms and biomaterial research.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
