Efficiently reduce protein disulfide bonds with this stable, odorless, 0.5M solution of TCEP reducing agent that is ideal for making reducing SDS-PAGE sample buffers.

IANBD Amide (N,N'-Dimethyl-N-(Iodoacetyl)-N'-(7-Nitrobenz-2-Oxa-1,3-Diazol-4-yl)Ethylenediamine)

Pure, crystalline urea (CH4N2O), CAS 57-13-6; denaturant with low UV-absorptivity for protein biology methods (elution, solubilization, refolding, storage).

Alexa Fluor™ 488 Hydrazide

Alexa Fluor™ 594 Carboxylic Acid, tris(triethylammonium) salt

5-ROX (5-Carboxy-X-Rhodamine, Triethylammonium Salt), single isomer

Immobilize or conjugate proteins using 1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide (CAS 25952-53-8), a water-soluble, carboxyl-to-amine crosslinker.

Crosslink amines to sulfhydryls with this long crosslinker composed of NHS-ester and maleimide groups at ends of an aliphatic, 12-atom (14.2A) spacer arm.

Alexa Fluor™ 647 NHS Ester (Succinimidyl Ester)

Crosslink amines to amines with dithiobispropionimidate; composed of imidoester groups at either end of a reducible (cleavable) disulfide-containing spacer arm.

Alexa Fluor™ 594 Alkyne (Alexa Fluor™ 594 Carboxamido-(5-(and 6-)Propargyl), Bis(Triethylammonium Salt)), mixed isomers

Pure, liquid (equals 14M), beta-mercaptoethanol (bME, 2BME, 2-ME, b-mer), CAS 60-24-2; thiol reducing agent for cleaving protein disulfide bonds (cystines cysteines).

Alexa Fluor 647 Carboxylic Acid, tris(triethylammonium) salt

Biotinylate protein amines with this doubly-long-chain (30.5A), NHS-ester biotinylation reagent containing a membrane permeable spacer arm for intracellular labeling.

Improve sequence coverage and protein identification for mass spectrometry using these individual, highly specific proteases in custom combinations.

Optimize applications where product integrity and risk minimization are paramount with our highest quality formulation of this disulfide reducing agent.

Pure, crystalline 2-aminoethanethiol (2-MEA-HCl, also called cysteamine-HCl), CAS 156-57-0; selectively reduces antibody hinge-region disulfide bonds.

Alexa Fluor™ 488 TFP ester
