Protein Labeling Reagents
Thermo Scientific™ EZ-Link™ Sulfo-NHS-SS-Biotin, No Weigh Format
Thermo Scientific™ EZ-Link™ Sulfo-NHS-SS-Biotin No-Weigh™ Format is a water-soluble, NHS-ester biotinylation reagent whose spacer arm includes a cleavable disulfide bond for reversible labeling of proteins and cell surface primary amines.
Molecular Probes™ Alexa Fluor™ Carboxylic Acid, tris(triethylammonium) salts
Alexa Fluor Carboxylic Acid tris(triethylammonium) salts are non-reactive forms of the Alexa Fluor dye that can be used as a reference standard for dye-conjugates. Choose from ten different Alexa Fluor free acid dyes that span the spectrum, from 350 to 750 nm, to meet your research needs.
Thermo Scientific™ EZ-Link™ Maleimide-PEG11-Biotin
Biotinylate reduced cysteines with this long, maleimide-activated, sulfhydryl-reactive biotinylation reagent with an 11-unit PEG spacer arm to enhance solubility and reach.
Invitrogen™ Alexa Fluor™ 594 C5 Maleimide
Alexa Fluor™ 594 is a bright, red fluorescent dye that can be excited using the 561 nm or 594 nm laser lines.
Invitrogen™ Alexa Fluor™ 488 Hydrazide
Alexa Fluor™ 488 Hydrazide is useful as a cell tracer and as a reactive dye for labeling aldehydes or ketones in polysaccharides or glycoproteins.
Thermo Scientific™ EZ-Link™ Sulfo-NHS-LC-Desthiobiotin, No-Weigh™ Format
Thermo Scientific™ EZ-Link™ Sulfo-NHS-LC-Desthiobiotin No-Weigh™ Format is a long-chain, amine-reactive labeling reagent whose biotin-like group is elutable from streptavidin, making it ideal for purified or cell surface protein labeling and purification.
Invitrogen™ Dansyl Ethylenediamine, 5-Dimethylaminonaphthalene-1-(N-(2-Aminoethyl))sulfonamide
5-dimethylaminonaphthalene-1-(N-(2-aminoethyl))sulfonamide (dansyl ethylenediamine)
Invitrogen™ Biotin-4-Fluorescein
Biotin-4-fluorescein can be used to quantitate available biotin-binding sites or the concentration of avidin or streptavidin through the strong quenching associated when this molecule binds to avidin.
Invitrogen™ Alexa Fluor™ 594 NHS Ester (Succinimidyl Ester)
Alexa Fluor™ 594 is a bright red dye. Used for stable signal generation in imaging and flow cytometry, Alexa Fluor™ 594 dye is water soluble and pH-insensitive from pH 4 to pH 10.
Invitrogen™ Alexa Fluor™ 405 Cadaverine
Alexa Fluor™ 405 Cadaverine is useful as a polar tracer and as a reactive dye for labeling proteins via a carboxylic acid moiety.
Invitrogen™ BODIPY™ TMR-X NHS Ester (Succinimidyl Ester)
BODIPY™ TMR-X dye is bright, orange fluorescent dye with similar excitation and emission to tetramethyrhodamine (TRITC) or Alexa Fluor™ 555 dye.
