Catalog Number: (1615138.)
Supplier: USP
Description: USP Reference Standards are specified for use in conducting official USP–NF tests and assays. USP also provides Reference Standards specified in the Food Chemicals Codex as well as authentic substances—high-quality chemical samples—as a service to analytical, clinical, pharmaceutical and research laboratories. To confirm accuracy and reproducibility, USP Reference Standards are rigorously tested and evaluated by multiple independent laboratories including USP, commercial, regulatory, and academic labs. USP also provide publicly available, official documentary standards for pharmaceutical ingredients in the USP–NF that link directly with our primary reference standards.
UOM: 1 * 500 mg

Supplier: AAT BIOQUEST
Description: SMCC is a non-cleavable and membrane permeable crosslinker with a spacer arm of 8.3 Å. It contains an amine-reactive succinimidyl ester (SE) and a sulfhydryl-reactive maleimide group. NHS esters react with primary amines at pH 7 to 9 to form stable amide bonds. Maleimides react with sulfhydryl groups at pH 6.5 to 7.5 to form stable thioether bonds. The SE group of SMCC is reacted with lysine residues on the carrier protein, converting them to reactive maleimides. SMCC 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.

Catalog Number: (PIERA35394)
Supplier: Thermo Fisher Scientific
Description: Thermo Scientific Pierce SMCC is a hetero-bifunctional crosslinker that contain N-hydroxysuccinimide (NHS) ester and maleimide groups that allow covalent conjugation of amine- and sulfhydryl-containing molecules. NHS esters react with primary amines at pH 7–9 to form amide bonds, while maleimides react with sulfhydryl groups at pH 6.5–7.5 to form stable thioether bonds. In aqueous solutions, NHS ester hydrolytic degradation is a competing reaction whose rate increases with pH. The maleimide group is more stable than the NHS-ester group, but will slowly hydrolyze and lose its reaction specificity for sulfhydryls at pH values > 7.5. For these reasons, conjugations with these crosslinkers are usually performed at pH 7.2–7.5, with the NHS ester (amine-targeted) reacted before or simultaneous with the maleimide (sulfhydryl-targeted) reaction.
UOM: 1 * 10 mg
