KpnI digest and gel #

Set up the KnpI digests described in the table below for each completed miniprep sample. Samples that have the insert should show two bands when run on a gel.

After incubating all samples for 45 mins at 37C ran products plus a control lane for each sample on 1% 1x TAE agarose gel at 120V for 45 minutes. Lane layout described in the table below.

Most samples digested but also looks like VR-20 sample may not actually have the insert. Thinking will still send for sequencing to make sure / see what it is.
