BSA that has been covalently attached to multiple dinitrophenyl (DNP) hapten molecules is commonly used as a protein tracer. Some applications of this tracer include the study of Fc receptor–mediated immune function and the IgE- and IgG-mediated responses to crosslinking of DNP-specific antibodies. Because DNP-BSA has a more defined molecular weight than the polydisperse dextrans, it may be better suited for some applications where the size of the tracer protein must be known with accuracy.
In addition to the DNP hapten–labeled BSA, we also offer several fluorescent conjugates of BSA, ovalbumin, and parvalbumin Protein Conjugates—Section 14.7
