The ability to precisely control and detect fluorescence allows for highly sensitive and specific analyses, making peptide fluorescence essential for advancements in molecular imaging, diagnostics, and drug discovery.
Peptides can exhibit fluorescence through two primary mechanisms: intrinsic fluorescence and extrinsic labeling.Pierce™ Quantitative Peptide Assays & Standards Intrinsic fluorescence arises from the presence of naturally fluorescent amino acid residues, primarily tryptophan (Trp), tyrosine (Tyr), and, to a lesser extent, phenylalanine (Phe). These aromatic amino acids absorb ultraviolet (UV) light and re-emit it at a longer wavelength.A circular permutation is a relationship between proteins whereby the proteins have a changed order of amino acids in theirpeptidesequence. Steady-state fluorescence measurements can be used to analyze the inherent fluorescence of these residues within a peptide sequence.
However, for many applications, especially those requiring specific detection wavelengths or enhanced signal, extrinsic labeling is employed. This involves covalently attaching a fluorescent dye or fluorophore to the peptide. This process, known as fluorescent labeling of peptides, allows for a wide range of emission spectra and enhanced fluorescence intensity, making them suitable for diverse applications like microscopy, flow cytometry (FACS), and in-vivo imagingCatalog number 23290 ; Price (USD). 494.65.
