Extracting eDNA in the lab

March 3, 2016

Thanks to the hard work of our citizen scientist volunteers, we now have monthly eDNA samples collected from Pigpen Branch from Summer 2015 until now. 

 

We're ramping up our lab work here in Knoxville, and we'll hopefully be sending final samples to be sequenced in the next few weeks. Pictured here are some of these samples as DNA is being extracted from the filter paper. This process involves a series of chemical reactions designed to isolate DNA and discard other contents--from course sediment to proteins--that might be in the samples. 

 

Stay tuned to see what salamanders we detect!
