Solid phase reactant for inhibition and removal of serine proteases and method of use

摘要

An affinity gel for the isolation of serine proteases from a biological sample. The affinity gel is modified for specificity for serine proteases by coupling an organophosphorous compound to the gel. The reaction is carried out in two steps. The hydrophilic gel is reacted with a phosphoryl trifluoride and then the coupled gel is further reacted with an alcohol to form the organophosphorous compound.
