The invention relates to a porin gene from Campylobacter jejuni SEQ ID NO:3. The gene has been designated porA and is 1275 bp in length and expresses a protein of 45.6 kDa having a pI of 4.44 SEQ ID NO:2. The sequencing and cloning of the gene makes possible various medical and industrial uses. For examples, knowledge of the DNA code makes it possible to design DNA probes for identification of the gene in samples for testing. A positive result indicates the presence of the gene in the sample and is a strong indicator of the presence of C. jejuni. Such probes can also be used to isolate the corresponding cDNA, that may then be amplified by polymerase chain reaction. The development …

Why it's free to use
- Filed March 25, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 25, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 25, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
