Abstract: A linker system is provided where a small molecule reactive group, e.g., an activity based probe which binds to certain enzymes at the active site, is linked through an aryl diazo linker to an affinity molecule such as biotin. The reactive group may comprise a number of functionalities known to react with a specific target to be studied. This enables the probe to be exposed to analytes, such as proteins and bind specifically to them to form a complex having an affinity molecule allowing immobilization of the bound analyte on an affinity column or other support, e.g. with streptavidin. Then, the linker is cleaved without causing removal of the affinity group or dissociation of the probe from the analyte. The linker is cleaved under mild reducing conditions, e.g., dithionite. The probe is synthesized along with the linker on a solid support.
