Protein Labeling Reagents
Thermo Scientific™ EZ-Link™ Sulfo-NHS-LC-Biotin
Thermo Scientific™ EZ-Link™ Sulfo-NHS-LC-Biotin is an intermediate-length, water-soluble biotinylation reagent for labeling antibodies, proteins and other molecules that have primary amines.
MilliporeSigma™ Novagen™ D-Desthiobiotin
Provides elution of Strep·Tag™ II proteins from biotin-binding site of Strep·Tactin™ resins
Thermo Scientific™ EZ-Link™ NHS-Biotin
Biotinylate protein amines (e.g., lysines) with a simple, short (13.5A), NHS-ester biotinylation reagent containing a membrane-permeable spacer arm for intracellular labeling.
Molecular Probes™ Alexa Fluor™ 488 C5 Maleimide
Alexa Fluor™ 488 is a bright, green fluorescent dye with excitation ideally suited to the 488 nm laser line.
Thermo Scientific™ EZ-Link™ Pentylamine-Biotin
Biotinylate proteins or surfaces using EDC or other amine-reactive crosslinkers with this short (18.9A) biotinylation reagent.
Thermo Scientific™ EZ-Link™ Biotin-LC-Hydrazide
Biotinylate glycoproteins (aldehydes of oxidized sugars) with this mid-length (24.7A) hydrazide-activated biotinylation reagent.
Thermo Scientific™ Sulfo-SBED Biotin Label Transfer Reagent, No-Weigh™ Format
Chemically tag purified proteins at primary amines to covalently crosslink and transfer biotinylation to protein interaction binding partners.
Thermo Scientific™ DyLight™ 650 NHS Ester
Label antibodies or other proteins as probes for fluorescence imaging assays with the full spectral range of NHS ester-activated DyLight Dyes.
MilliporeSigma™ Calbiochem™ β-Cyclodextrin
Homogeneous cyclic α1,4-linked D-glucopyranose units in a seven-member ring. Forms clathrates. Suitable for use with dansyl chloride to form water-soluble complexes for fluorescent labeling of proteins.
Molecular Probes™ Alexa Fluor™ 405 NHS Ester (Succinimidyl Ester)
Alexa Fluor™ 405 is a blue-fluorescent dye optimal for use with the 405 nm violet laser.
Thermo Scientific™ Sulfo-SHPP (Water-Soluble Bolton-Hunter Reagent)
Add tyrosine (tyrosyl) groups to proteins to increase the number of iodine-125 labeling (iodination) sites using an amine-reactive, NHS ester compound.
Thermo Scientific™ EZ-Link™ Alkoxyamine-PEG12-Biotin
Biotinylate glycoproteins (aldehydes of oxidized sugars) with a very long (55.4A), pegylated biotinylation reagent containing a 12-unit PEG spacer for length and solubility.
Thermo Scientific™ GalNAz (N-azidoacetylgalactosamine tetraacylated)
Study glycoproteins using in vivo metabolic labeling and chemoselective ligation to phosphine reagents with these azide-tagged sugars (GlcNAz, GalNAz, ManNAz).
Thermo Scientific™ DyLight™ 594 Maleimide
Label antibodies or other proteins as probes for fluorescence imaging assays with the full spectral range of maleimide-activated DyLight Dyes.
