Description: 5(6)-TAMRA is the mixture of two carboxy tetramethylrhodamine (TMR) isomers. It is used to modify amino and hydroxy groups using EDC-mediated couplings when there are difficulties in using 5(6)-TAMRA, SE. TAMRA is one of the most popular fluorophores used in various bioconjugations.

Catalog Number: (PI22360)
Supplier: Invitrogen
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.
