Protein Labeling


Site-specific labeling technique refers to the covalent attachment of molecules like biotin, fluorophore, enzyme and radioactive isotopes to specific sites of the target protein. Protein labeling is extensively used to enable the detection and purification of the desired protein, and to facilitate the tracking of protein expression, localization, interaction, activity and conformational changes in complicated cellular signaling events.

Features

  Comprehensive list of labeling reagents
  Site-specific labeling
  Cost-effective
  Short turn-around time

Profacgen has developed a series of protein labeling techniques and reagents to meet your research requirements. The most popular labels our customers choose include fluorescent probes (Phycoerythrin, allophycocyanin, fluorescein, tetramethylrhodamine, fluor dyes), enzyme conjugates (horseradish peroxidase and alkaline phosphatase) and biotin. We also provide N15 & C13 labeling for your NMR experiments.

Protein Labeling

Site-specific protein labeling attaches small molecules to particular site(s) on a protein target to introduce novel chemical and physical properties selectively, which further enables the target protein to be monitored or manipulated with diverse technologies.

Profacgen offers various labeling services for the site-specific labeling of target proteins to ensure the quality of your downstream applications. Our service can be tailored according to your specific requirements.
