Protein Labeling Reagents
Invitrogen™ Alexa Fluor™ 488 Cadaverine
Alexa Fluor™ 488 Cadaverine is useful as a polar tracer and as a reactive dye for labeling proteins via a carboxylic acid moiety.
Thermo Scientific™ EZ-Link™ NHS-PEG12-Biotin, No-Weigh™ Format
Biotinylate protein amines and maximize solubility of proteins with this very long (56.0A) NHS-ester biotinylation reagent containing a pegylated, water-soluble spacer arm.
Molecular Probes™ Alexa Fluor™ 790 NHS Ester (Succinimidyl Ester)
Alexa Fluor™ 790 is a bright and photostable near-IR dye that is spectrally similar to indocyanine green (ICG) and the IRDye™ 800 dye.
Invitrogen™ Alexa Fluor™ 546 C5 Maleimide
Alexa Fluor™ 546 is a bright, orange fluorescent dye that can be excited using the 488 nm or 532 nm laser lines.
Thermo Scientific™ NHS-Rhodamine (5/6-carboxy-tetramethyl-rhodamine succinimidyl ester), mixed isomer
Label antibodies, proteins and other molecules for fluorescence imaging (ex 546; em 572-615) using these activated derivatives of red-fluorescent rhodamine dye.
Thermo Scientific™ EZ-Link™ Hydrazide-PEG4-Biotin
Biotinylate glycoproteins (aldehydes of oxidized sugars) with this mid-length (31.3A), pegylated biotinylation reagent containing a 4-unit PEG spacer for solubility.
Invitrogen™ Alexa Fluor™ 488 C5 Maleimide
Alexa Fluor™ 488 is a bright, green fluorescent dye with excitation ideally suited to the 488 nm laser line.
Invitrogen™ Alexa Fluor™ 750 NHS Ester (Succinimidyl Ester)
Alexa Fluor™ 750 is a bright and photostable near-IR dye that is spectrally similar to Cy7.
Invitrogen™ Alexa Fluor™ 514 NHS Ester (Succinimidyl Ester)
Used for stable signal generation in imaging and flow cytometry, Alexa Fluor™ 514 dye is water soluble and pH-insensitive from pH 4 to pH 10.
Invitrogen™ Monobromobimane (mBBr), FluoroPure™ grade
Because it is manufactured at our ISO 13485—certified facilities in Eugene, Oregon, we can guarantee that FluoroPure grade monobromobimane is greater than or equal to 98% pure by HPLC.
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.
Invitrogen™ Alexa Fluor™ 700 NHS Ester (Succinimidyl Ester)
Alexa Fluor™ 700 is a bright and photostable near-IR dye that can be excited with a xenon-arc lamp, far-red diode lasers, or dye pumped lasers operating in the 675–700 nm range.
Invitrogen™ Cascade Blue™ hydrazide, Trisodium Salt
The cell-impermeant, fixable, polar tracer Cascade Blue™ hydrazide can be used to investigate cell-cell and cell-liposome fusion as well as membrane permeability and transport through gap junctions or cell uptake during pinocytosis.
