55750-62-4 Usage
Description
3-Maleimido-propionic NHS ester contains a maleimide group and an NHS ester. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol.

Uses
Different sources of media describe the Uses of 55750-62-4 differently. You can refer to the following data:
1. 3-Maleimidopropionic acid N-hydroxysuccinimide ester is a reagent that is widely used for generating stable maleimide-activated carrier proteins that can spontaneously react with sulfhydryls. Alternatively these relatively stable maleimide-activated intermediates may be lyophilized and stored for later conjugation to a hapten.
2. A short, sulfhydryl and amino reactive heterobifunctional crosslinking reagent, N-Succinimidyl 3-maleimidopropionate can also been used in immunodiagnostics.
Check Digit Verification of cas no
The CAS Registry Mumber 55750-62-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,7,5 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 55750-62:
(7*5)+(6*5)+(5*7)+(4*5)+(3*0)+(2*6)+(1*2)=134
134 % 10 = 4
So 55750-62-4 is a valid CAS Registry Number.

Practical synthesis of maleimides and coumarin-linked probes for protein and antibody labelling via reduction of native disulfides
Song, Hong Y.,Ngai, Mun H.,Song, Zhen Y.,MacAry, Paul A.,Hobley, Jonathan,Lear, Martin J.
experimental part, p. 3400 - 3406 (2010/01/06)
The cellular tracking, detection and sensing of protein or antibody movement are important aspects to advance our understanding of biomolecular interactions and activity. Antibodies modified with fluorescent dyes are also valuable tools, especially in immunology research. We describe here a proof-of-principle study of a new water-soluble coumarin probe with a maleimide thiol-reacting unit to fluorescently tag biomolecules. Highlights include: (1) a convenient water-based preparation of N-substituted maleimides, (2) a one-pot preparation of activated maleimido-esters, and (3) a bio-conjugation protocol for the selenol-promoted reduction of native disulfide bonds and the 'site-specific' labelling of antibodies with no significant loss of activity.
