Using a unique, nontoxic adjuvant compound of poly(I:C) and anti-CD40 MAb, a battery of eight mouse monoclonal antibodies was generated against native green fluorescent protein. All were effective to varying degrees for immunostaining paraformaldehyde-fixed cells, six for staining sections of paraffin-embedded tissue, all to varying degrees in fluorescent-activated cell sorting, five for immunoprecipitation, and seven for chromatin immunoprecipitation. None worked in denaturing Western blots since the target was the native GFP protein. Both the hybridomas and antibodies are available at cost through DSHB, a non-profit National Resource created by the National Institutes of Health.
