Application

O-(2-Nitrobenzyl)-L-tyrosine hydrochloride (NBY) is a tyrosine derivative with an o-nitrobenzyl photocage that can be cleaved with 365 nm irradiation. NBY has been genetically encoded into multiple proteins, providing an ″on switch″ for regulation. Photocaged amino acids such as these are also useful in the synthesis of photocleavable chemical tools for spatial and temporal control over released molecules in biological applications.

Product can be used with our line of photoreactors: Including Penn PhD (Z744035) & SynLED 2.0 (Z744080)

Although chemists can synthesize virtually any small organic molecule, our ability to rationally manipulate the structures of proteins is quite limited, despite their involvement in virtually every life process. For most proteins, modifications are largely restricted to substitutions among the

Antibodies have found applications in several fields, including, medicine, diagnostics, and nanotechnology, yet methods to modulate antibody-antigen binding using an external agent remain limited. Here, we have developed photoactive antibody fragments by genetic site-specific replacement of single tyrosine residues with
