Crosslinking, Labeling and Protein Modification
Thermo Scientific™ SMPB (succinimidyl 4-(p-maleimidophenyl)butyrate)
Crosslink amines to sulfhydryls with this mid-length crosslinker composed of NHS-ester and maleimide groups at ends of an aromatic, 10-atom (11.6A) spacer arm.
Invitrogen™ BODIPY™ FL-X NHS Ester (Succinimidyl Ester)
BODIPY™ FL-X dye is bright, green fluorescent dye with similar excitation and emission to fluorescein (FITC) or Alexa Fluor™ 488 dye.
Thermo Scientific™ Sulfo-SIAB (sulfosuccinimidyl (4-iodoacetyl)aminobenzoate)
Crosslink amines to sulfhydryls with this mid-length, water-soluble crosslinker composed of sulfo-NHS-ester and iodoacetyl (haloacetyl) groups at ends of a 9-atom spacer arm.
Thermo Scientific™ Pierce™ Antibody Biotinylation Kit for IP
Label primary antibodies with biotin for use in agarose or magnetic bead immunoprecipitation experiments using the Thermo Scientific™ Pierce™ Antibody Biotinylation Kit for IP.
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™ EGS (ethylene glycol bis(succinimidyl succinate))
Crosslink amines to amines with this membrane permeable crosslinker composed of NHS-ester groups and a 16.1A hydroxylamine-cleavable spacer arm.
Thermo Scientific™ DyLight™ 755 Maleimide
Label antibodies or other proteins as probes for fluorescence imaging assays with the full spectral range of maleimide-activated DyLight Dyes.
Thermo Scientific™ SPDP (succinimidyl 3-(2-pyridyldithio)propionate)
Crosslink amines to sulfhydryls with this crosslinker composed of NHS-ester and pyridyldithiol groups on 3-atom spacer arm; forms cleavable disulfide bonds with cysteines.
Thermo Scientific™ Pierce™ Iodination Tubes
Reliably label (iodinate) proteins and peptides with iodine-125 using glass test tubes that are pre-coated (activated) with iodination reagent.
Thermo Scientific™ TMTzero™ Label Reagent, 5 x 0.8 mg
The Thermo Scientific TMTzero Label Reagent serves as a 'light' tag for MS-level peptide quantitation similar to duplex isotopic metabolic labeling, such as SILAC, or isotopic dimethylation labeling.
Thermo Scientific™ Pierce™ Iodination Beads
Easily and gently label (iodinate) proteins and peptides with iodine-125 using reagent-coated polystyrene beads that can be removed following reaction.
Thermo Scientific™ HABA (4'-hydroxyazobenzene-2-carboxylic acid)
A colored, biotin assay reagent HABA (4'-hydroxyazobenzene-2-carboxylic acid) to measure biotinylation levels of biotinylated antibodies or proteins.
Thermo Scientific™ EZ-Link™ Sulfo NHS-SS Biotinylation Kit
Biotinylate protein amines with this cleavable, mid-length (24.3A), water-soluble, NHS-ester biotinylation reagent containing a cleavable disulfide bond in the spacer arm.
Thermo Scientific™ PMPI (p-maleimidophenyl isocyanate)
Short (8.7A) hydroxyl-to-sulfhydryl crosslinker; isocyanate and maleimide groups; label -OH by urethane bonds for conjugation to cysteines by thioether bonds.
