Version 2 Oligos (Started 1/6/2017)[edit]

Back to Calendar

From Saturday's results it looks like there is a product at the correct bp size for the version 2 oligos (209bp). What is more exciting is that both sample lanes have it, and none of the negative control lanes have it! So let's send it to the sequencer.
