Here you will find Click-Photocrosslinking compounds for photo-affinity labeling (PAL)
You can use these compounds for techniques such as SDS-PAGE, immunoprecipitation, biotin-streptavidin affinity purification and mass spectrometry.
Alkyl diazirines are photo-reactive functional groups frequently used in photo-affinity labeling (PAL). They are compact in size, being nearly isosteric to a methyl group, and they are activated at a wavelength of light (~355 nm) that is not damaging to protein(s). Photo-crosslinked protein targets are then visualized by the reporter group (e.g. fluorophore, biotin, or radioactive label).
