Catalog Number: (PIER22297)
Supplier: Thermo Fisher Scientific
Description: Thermo Scientific Pierce BMPH is a short, maleimide-and-hydrazide crosslinker for conjugating sulfhydryls (cysteines) to carbonyls (aldehyde or ketones, such as those formed by oxidation of glycoprotein carbohydrates).
UOM: 1 * 50 mg


Catalog Number: (PIER22331)
Supplier: Thermo Fisher Scientific
Description: Thermo Scientific Pierce BMB is a mid-length, maleimide crosslinker for covalent, irreversible conjugation between sulfhydryl groups (e.g., protein or peptide cysteines).
UOM: 1 * 50 mg


Catalog Number: (PIER22295)
Supplier: Thermo Fisher Scientific
Description: Thermo Scientific Pierce AMAS is an amine-to-sulfhydryl crosslinker that contains NHS-ester and maleimide reactive groups at opposite ends of a very short spacer arm (4.4 angstroms).
UOM: 1 * 50 mg


Supplier: Thermo Fisher Scientific
Description: Pierce™ Glycoprotein Carbohydrate Estimation Kit enables the amount of protein glycosylation to be measured as a percentage of total purified protein mass.

Catalog Number: (PIER31491)
Supplier: Thermo Fisher Scientific
Description: Pierce™ Horseradish Peroxidase
UOM: 1 * 100 mg


Supplier: Thermo Fisher Scientific
Description: 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.

Catalog Number: (PIER21277)
Supplier: Thermo Fisher Scientific
Description: The Pierce™ his protein interaction pull-down kit contains the necessary components to capture and purify proteins that interact with his-tagged fusion proteins.
UOM: 1 * 1 KIT


Catalog Number: (PIER21121)
Supplier: Thermo Fisher Scientific
Description: Pierce™ Avidin is used in biotin-based detection methods, including Western blotting or ELISA detection with appropriate enzyme substrates. It is a purified protein from egg whites and it is stable over wide range of pH and temperature.
UOM: 1 * 10 mg


Supplier: Thermo Fisher Scientific
Description: Pierce™ Protein A/G agarose is a affinity resin for antibody purification.

Catalog Number: (PIER34070)
Supplier: Thermo Fisher Scientific
Description: The 1-Step NBT/BCIP plus suppressor is a one-component alkaline phosphatase substrate that inhibits endogenous phosphatase activity. This substrate reacts with calf intestinal alkaline phosphatase to produce a dark purple precipitate and is ideal for immunohistochemistry and <i>in situ</i> hybridisation applications.
UOM: 1 * 100 mL


Catalog Number: (PIER34000)
Supplier: Thermo Fisher Scientific
Description: Pierce™ CN/DAB Substrate Kit is for chromogenic detection of horseradish peroxidase in immunohistochemistry and immunoblotting applications. The formed product is a black precipitate that photographs well and is useful in double staining applications. The coloured product is soluble in xylenes but not soluble in aqueous buffer such as Tris or phosphate. This combination of DAB and CN has a synergistic effect that results in greater sensitivity than either reagent alone.
UOM: 1 * 1 KIT


Catalog Number: (PIER44918)
Supplier: Thermo Fisher Scientific
Description: Pierce™ chicken IgY purification kit purifies chicken antibodies from hen egg yolks using a unique delipidation reagent to separate protein from lipid and a precipitation reagent to selectively isolate the IgY fraction.
UOM: 1 * 1 KIT


Catalog Number: (PIER22360)
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 * 50 mg

Catalog Number: (PIER23238)
Supplier: Thermo Fisher Scientific
Description: The bradford protein assay is the preferred colorimetric assay for quantifying total protein concentration. The Pierce™ coomassie plus protein assay is a ready-to-use, reducing agent-compatible, improved bradford assay reagent to quickly measure (A595 nm) total protein concentration compared to a protein standard.
UOM: 1 * 300 mL
