m-PEG11-Acid CAS:2280998-74-3 is a linear, monodisperse, and hydrophilic polymer featuring an 11-unit polyethylene glycol (PEG) chain with a terminal carboxylic acid group. This reagent is widely used in pharmaceutical research and development for the PEGylation of biomolecules, which can improve the biocompatibility, solubility, and pharmacokinetic properties of therapeutics.
The PEG chain contains 11 ethylene glycol units, providing a flexible spacer and enhancing solubility, biocompatibility, and stability of the conjugate.The terminal carboxylic acid group facilitates conjugation with amine-functionalized biomolecules, such as proteins or peptides, using standard coupling reactions, e.g., carbodiimide or activated ester chemistries.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
