3-nitro-L-phenylalanine 3-nitro-L-phenylalanine can quench Trp fluoresence via FRET in a distance dependent manner. May also be useful as a control for use in studies of the roles of 3-nitroTyr in protein structure-function. Published: Fully Reviewed
3-nitro-L-tyrosine 3-Nitro-L-tyrosine 3-nitroTyr is a natural post-translational modification of proteins typically resulting from protein oxidation by peroxynitrite. It increases in many diseases and with age. Still unknown is if it can be reversed (by a denitrase) and if it has has a purposeful signaling role, or if it is only a modification associated with pathologies. It is known in some cases to contribute to disease pathology, but in most cases it is unknown how much it causes pathology vs. being a consequence of pathology. The ability to site specifically and quantitatively place 3-nitroTyr in positions in proteins that have been seen to occur in association with disease is a key tool to answer questions about its possible roles in normal physiology and disease.

4'-TCOK (TCO) 4'TCO-lysine Reactive handle for IEDDA. Published: Fully Reviewed
acridonylalanine acridonylalanine It is a blue-wavelength fluorescent probe used for monitoring conformational changes and other molecular dynamics in proteins. The 2013 and 2021 foundational publications provide information on its properties, and a 2023 paper (doi: 10.1002/pro.4633) provides examples of its use in FRET studies. Published: Fully Reviewed
Azidohomoalanine Azidohomoalanine click chemistry, BONCAT (Bioorthogonal non-canonical amino-acid tagging) proteomics Published: Fully Reviewed
Azidonorleucine azidonorleucine Biorthogonal Ligation, Click Chemistry labeling with fluorescence or affinity labels. Specifically used for cell-specific proteomics studies using "bioorthogonal noncanonical amino acid tagging" (BONCAT) proteomics. Contrasts with Azidohomoalanine which does not allow cell-specific studies. Published: Fully Reviewed
