With diisobutylene-maleic acid (DIBMA), you can directly extract membrane proteins from cells without an intermediate step of detergent solubilization, like with SDS, which would usually interfere with the protein's function. Another advantage of DIBMA as a tool for protein solubilization is the lack of an absorbance maxima at 280 nm. In comparison to SMAs, this would usually interfere with protein quantification, as aromatic amino acids absorb at the same spectrum.

Sulfo-DIBMA is an electroneutral modification of existing DIBMAs. It does not interfere with charge-sensitive interactions between proteins and lipids. This innovation opens up a wider range of experimental research in terms of charge-sensitive membrane protein processes like protein-protein and protein-lipid interactions. In addition, Sulfo-DIBMA belongs to a new generation of DIBMA’s which are RAFT polymerized. This achieves a reduction in both monomer size and greater monodispersity. With diisobutylene-maleic acid (DIBMA), you can directly extract membrane proteins from cells without an intermediate step of detergent solubilization, like with SDS, which would usually interfere with the protein's function. Another advantage of DIBMA is the lack of an absorbance maxima at 280 nm. SMAs, in comparison, usually interfere with protein quantification, as aromatic amino acids absorb at the same spectrum.
Another significant advantage of Sulfo polymers compared to other polymers is the wide pH range in which they remain stable. The buffer in which the polymer is supplied has a pH of 7.5, but the polymer itself remains stable between pH 4 and pH 10. The special physicochemical properties of Sulfo-DIBMAs make them ideal for cryo-TEM and other downstream applications.

DL-Dithiothreitol is a Clelands reagent; Protective agent for sulfhydryl groups (-SH). Quantitatively reduces disulfides (-S-S- to -SH). In this reaction the DTT is oxidized to the cyclic disulfide which ensures the reduction of other disulfides in solution. Disulfide reduction occurs quickly at pH 8.

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.
