<h3>Overview</h3>
<p>Methoxy PEG Succinimidyl Succinamide is a heterobifunctional crosslinker used to conjugate amine-containing molecules with carboxylic acids. The <strong>methoxy-terminated polyethylene glycol (mPEG)</strong> chain provides solubility, while the <strong>succinimidyl ester</strong> group reacts with primary amines. Formula: C<sub>n</sub>H<sub>2n+1</sub>O(CHOCH<sub>2</sub>)<sub>x</sub>NHCOO(CH<sub>2</sub>)<sub>4</sub>COCOO; CAS No.: 106598-76-5.</p>
<h3>Application</h3>
<ul>
<li><strong>Antibody-Drug Conjugates (ADCs):</strong> Attaches cytotoxic payloads to monoclonal antibodies for targeted cancer therapy.</li>
<li><strong>Protein Engineering:</strong> Modifies therapeutic proteins to enhance serum half-life via PEGylation.</li>
<li><strong>Diagnostics:</strong> Labels enzymes or fluorophores on solid-phase supports for immunoassays.</li>
</ul>
<h3>Precautions</h3>
<p>Store at -20°C under inert atmosphere to prevent hydrolysis. Avoid contact with skin and eyes; use in a fume hood due to potential irritancy. Do not use in injectable formulations without rigorous purity validation.</p>
