Did you mean: Methoxy Polyethylene glycol) p-aminobenzoic acid
AI Overview
Methoxypoly(ethylene glycol) p-aminobenzoic acid (mPEG-PABA) is a linear, monofunctional PEG derivative used primarily in pharmaceutical and biotechnology research for modifying biologically active compounds. It consists of a methoxypoly(ethylene glycol) chain conjugated with a p-aminobenzoic acid (PABA) moiety, which allows for further chemical reactions such as coupling.
Key Aspects of mPEG-PABA
- Structure & Function: The PEG chain provides high water solubility, flexibility, and stability, while the PABA group offers a reactive site for conjugation, such as through acylation, alkylation, or diazotization.
- Applications: It is used as a pegylation agent to enhance the solubility, stability, and pharmacokinetic profiles of therapeutic molecules and nanoparticles. It may be utilized to improve drug delivery and reduce immunogenicity of therapeutic agents.
- Molecular Weights: Commonly available in standard molecular weights such as 2KDa, 5KDa, 10KDa, 20KDa, and 40KDa.
- Storage: It is recommended to store mPEG-PABA at -20 5℃ in a dry environment.
- Manufacturer: It is available from specialty chemical suppliers like Sinopeg.
