ABTS (Diammonium 2,2'-azinobis[3-ethyl-2,3-dihydrobenzothiazole-6-sulfonate]) solution

Catalog Number: (IC04821809)

Supplier: MP Biomedicals

Description: 2,2'-Azino-bis-(3-ethylbenzthiazoline-6-sulfonic Acid) Solution is oxidized to a radical action showing absorption maxima at 820 nm, 734 nm, 650 nm and 405 nm, in the presence of hydrogen peroxide and HRP. The latter frequency demonstrates a significant molar extinction coefficient and is generally employed for most ABTS assays. Stopping the reaction with acid does not alter the 405 nm spectrum allowing kinetic and endpoint methods to be measured at the same wavelength. Provided as a room temperature stable, single component ABTS solution satisfactory for quantitative analysis of HRP based systems.

DSP (Dithiobis(succinimidyl propionate)), No-Weigh™ Format, Pierce™

Catalog Number: (103523-924)

Supplier: Invitrogen

Description: Thermo Scientific Pierce DSP (Lomant's Reagent) is a water-insoluble, homo-bifunctional N-hydroxysuccimide ester (NHS ester) crosslinker that is thiol-cleavable, primary amine-reactive, and useful for many applications. DSP contains an amine-reactive NHS ester at each end of an 8-carbon spacer arm. NHS esters react with primary amines at pH 7–9 to form stable amide bonds and releasing N-hydroxy-succinimide. Proteins, including antibodies, generally have several primary amines in the side chain of lysine (K) residues and the N-terminus of each polypeptide that are available as targets for NHS ester crosslinking reagents. DSP is non-sulfonated and insoluble in water, so it must first be dissolved in an organic solvent and then added to the aqueous reaction mixture. Because DSP does not possess a charged group, it is lipophilic and membrane-permeable and so useful for intracellular and intramembrane conjugation. A sulfonated analog of DSP (DTTSP) is water soluble. DSS, the non-cleavable analog of the DSP crosslinker is also available for applications that require a stable spacer arm that cannot be cleaved in the presence of reducing agents.
