N-Succinimidoxycarbonyl-β-alanine N-Succinimidyl Ester is a short amino reactive homobifunctional crosslinking reagent. N-Succinimidoxycarbonyl-β-alanine N-Succinimidyl Ester, a valuable research compound, finds utility in polymer coupling to proteins. Its significance lies in promoting greater selectivity among the amino groups present in a protein, resulting in a reduced mixture of heterogeneous PEG-protein conjugates. This specificity ensures that only the most nucleophilic and solvent-exposed amines can undergo the desired reaction, leading to improved control over the coupling process.

I ordered and received this material about a couple weeks ago. I left each bottle in its packaging but did not immediately store at -20C. It’s been in my lab drawer at room temperature for two weeks. Is the material still fully active?

Asked by: ChemSynth123
Thank you for your question. The quality of N-Succinimidoxycarbonyl-β-alanine N-Succinimidyl Ester (CAS 21994-89-8): sc-212275 has not been compromised after two weeks at room temperature and should be fully active. It is recommended to store sc-212275 at -20ºC to ensure its quality over a long period of time (at least one year).
