Thermo Fisher, A30009, Alexa Fluor™ 647 Microscale Protein Labeling Kit

Quantity: 1 Kit
Unit Size: Each
Microscale Protein Labeling Kits provide a convenient means for attaching a fluorescent label to a small amount of antibody or protein (20–100 μg). The kits are available in four Alexa Fluor™ colors (or biotin) and supply everything needed for three labeling and separation reactions.Important Features of Microscale Protein Labeling Kits:
• Labeled proteins typically ready to use typically in 2 hours (∼30 minutes hands-on time)
• Optimized for 20–100μg of protein with molecular weights between 12 and 150 kDa
• Purified using convenient spin filters with yields between 60 and 90%
• Stabilizing proteins must be removed from the sample before labelingStable Reaction Chemistry and Superior Alexa Fluor™ DyesIn the Microscale Protein Labeling Kits, the reactive dye contains a succinimidyl (NHS) ester moiety that reacts with primary amines of proteins to form stable dye-protein conjugates. Compared to traditional dyes, Alexa Fluor™ dyes are brighter, more photostable, and more pH resistant between pH 4 and 10. And generally when using Alexa Fluor™ dyes, higher degrees of labeling can be achieved without intramolecular quenching. For details see Alexa Fluor™ Dyes Spanning the Visible and Infrared Spectrum—Section 1.3.Learn More About Protein and Antibody LabelingWe offer a wide selection of Molecular Probes™ antibody and protein labeling kits to fit your starting material and your experimental setup. See Antibody Labeling from A to Z or use our Labeling Chemistry Selection Tool for other choices.
