<h3>Overview</h3>
<p>Methoxy PEG tri-Glutamic Acid is a specialized polymeric reagent used for bioconjugation. It features a methoxy-terminated polyethylene glycol backbone linked to three glutamic acid units, facilitating precise drug attachment. <strong>Chemical Formula</strong>: C<sub>x</sub>H<sub>y</sub>N<sub>z</sub>O<sub>w</sub>; <strong>CAS No.</strong>: Typically varies by specific MW (e.g., ~1500-5000 Da). The synthesis involves activated ester coupling under controlled pH.</p>
<h3>Application</h3>
<ul>
<li><strong>Antibody-Drug Conjugates (ADCs)</strong>: Serves as a hydrophilic spacer to enhance solubility and reduce immunogenicity.</li>
<li><strong>Polymer Therapeutics</strong>: Used in prodrug formulations to extend circulation half-life of therapeutic proteins.</li>
<li><strong>Biomaterials</strong>: Functionalizes surfaces for targeted delivery systems in oncology research.</li>
</ul>
<h3>Precautions</h3>
<ul>
<li>Store at -20°C under inert atmosphere to prevent hydrolysis.</li>
<li>Handle with appropriate PPE; avoid direct skin contact due to potential sensitization.</li>
<li>Not approved for clinical use without further regulatory validation.</li>
