dnature diagnostics & research

About us

dnature diagnostics & research Ltd was started in 2009 as a specialist PCR and qPCR business.  While we provide reagents and equipment in this area, we're a little different in that we also have our own testing & research laboratory, distribute proprietary kits that we've developed, as well as offering consultancy services.

We are experts in qPCR and high resolution melting analysis (HRMA) and we use these techniques for testing, ranging from plant pathogens, bee viruses & diseases to other primary industries as well. More recently we've moved into clinical diagnostics and supply NZ laboratories with a COVID-19 qPCR that we've developed.  Other services we provide include sequencing for bacteria, yeast and fungi identification.  By using the products we distribute in our lab means that we know what we sell really well, and if we don't like it, well you won't see it from us.

We also develop research and diagnostic qPCR assays for other laboratories & industries, as well ourselves, using SYBR, hydrolysis probe, HRMA and multiplex designs.  Drop us a line if you want to chat.
