Beschreibung: Thermo Scientific Pierce coomassie brilliant blue dyes are composed of one of the most common forms of coomassie dye, which is a key component of various colorimetric protein gel stains. Coomassie R-250 and G-250 dyes are two chemical forms of a disulphonated triphenylmethane compound that is commonly used as the basis of stains for detection of proteins in gel electrophoresis and bradford-type assay reagents for protein quantitation. The R-250 (red-tinted) form lacks two methyl groups that are present in the G-250 (green-tinted) form, which is also called colloidal coomassie dye.

Beschreibung: This antibody labeling system uses nickel chelated agarose to temporarily immobilise antibody molecules via their histidine-rich Fc regions. Once held in place on the gel, the antibody can be biotinylated at either sulfhydryl groups (after mild reduction or disulfide bonds) or primary amines. Excess labeling reagent and by-products are then washed away before recovering the labeled and purified antibody from the gel using a mild imidazole solution. No gel filtration or dialysis are needed.

Beschreibung: Pierce glutathione coated plates are coated with intact glutathione (GSH) and pre-blocked for use in capture and detection assays involving glutathione-S-transferase (GST) fusion proteins. These coated plates can be used in the analysis of cell lysates to determine the presence and concentration of the GST-fusion protein produced in an expression system. Plates can also be used to capture and coat fusion proteins via their GST tag for subsequent binding assays involving the recombinant protein. As the plates are pre-blocked, initial purification of the cell lysates is not necessary.

Hersteller Artikel Nummer : 22360

Beschreibung: 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.
