Protein Labeling Reagents
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™ Amine-PEG11-Biotin
Biotinylate proteins or surfaces using EDC or other amine-reactive crosslinkers with this long (53.2A) biotinylation reagent containing an 11-unit polyethylene glycol spacer.
Invitrogen™ Alexa Fluor™ 430 NHS Ester (Succinimidyl Ester)
Used for stable signal generation in imaging and flow cytometry, Alexa Fluor™ 430 dye is water soluble and pH-insensitive from pH 4 to pH 10.
Molecular Probes™ Alexa Fluor™ 488 TFP ester
Alexa Fluor™ dyes are reactive molecules that can be used to add a fluorescent label to the primary amines (R-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.
Thermo Scientific™ EZ-Link™ NHS-Desthiobiotin
Label intracellular proteins for affinity purification with streptavidin beads
