pan Nuclear Pore Complex Marker Products

This monoclonal was raised by injecting mice with yeast nuclear preparations and screening the resulting hybridomas by immunofluorescence on yeast cells. 39C7 was one of a series of clones which strongly and specifically labeled the nuclear pore complex. When this antibody was tested on cells from other species, including rat, mouse and human cells, it has invariably strongly stained nuclear pore complexes, so it appears to be an excellent and panspecific marker for these important structures. 39C7 does not work well on western blots so we are currently unsure of the exact identity of the protein to which it binds.
