I saw a self-service stand for genetyping set up by an unknown company in
front of our mouse house, and I have not seen any request for the service in
these one and half years. I guess PIs hardly trust company service on this
genotyping thing.
But I will definitely try the qPCR if results are convincing. You may want
to have a promotion rate for the first a few trials, so you can establish
rapport with PIs during the confidence-building period.
