Protein Labeling Reagents
Invitrogen™ BODIPY™ 493/503 NHS Ester (Succinimidyl Ester)
BODIPY™ 493/503 dye is bright, green fluorescent dye with similar excitation and emission to fluorescein (FITC) or Alexa Fluor™ 488 dye.
Molecular Probes™ Alexa Fluor™ 647 Azide, Triethylammonium Salt
The far red-fluorescent Alexa Fluor™ 647 azide is reactive with terminal alkynes via a copper-catalyzed click reaction.
Thermo Scientific™ EZ-Link™ Psoralen-PEG3-Biotin
Biotinylate DNA or RNA via intercalation and conjugation with thymine- and other pyrimidine-containing bases with this light-activated biotinylation reagent.
Invitrogen™ Tetramethylrhodamine-5-Iodoacetamide Dihydroiodide (5-TMRIA), single isomer
Tetramethylrhodamine-5-Iodoacetamide Dihydroiodide (5-TMRIA), single isomer
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 C5 Maleimide
Alexa Fluor™ 594 is a bright, red fluorescent dye that can be excited using the 561 nm or 594 nm laser lines.
Thermo Scientific™ EZ-Link™ Iodoacetyl-PEG2-Biotin
Biotinylate reduced cysteines (-SH groups) at high pH with this haloacetyl-activated, sulfhydryl-reactive biotinylation reagent containing polyethylene glycol for solubility.
Invitrogen™ 5-FAM, SE (5-Carboxyfluorescein, Succinimidyl Ester), single isomer
5-FAM, SE (5-Carboxyfluorescein, Succinimidyl Ester), single isomer
Invitrogen™ ARP (N-(aminooxyacetyl)-N'-(D-Biotinoyl) hydrazine, Trifluoroacetic Acid Salt)
ARP (N-(aminooxyacetyl)-N'-(D-Biotinoyl) hydrazine, Trifluoroacetic Acid Salt)
Thermo Scientific™ EZ-Link™ TFPA-PEG3-Biotin
Biotinylate molecules without common functional groups for coupling with this efficient, light-activated biotinylation reagent based on tetrafluorophenyl azide.
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™ 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.
