Just wanted to let folks know that there appears to be a problem with the
yeast expression vectors deposited at ATCC. On at least two occasions, we
have received plasmids that contain the wrong marker (e.g., his rather
than leu) and/or wrong promoter (Gal rather than ADH, and visa versa).
Although they are willing to refund your money, they are unwilling to
resolve the confusion. They also acknowledge that there have been
complaints but again, are unwilling to do anything. So, beware when
obtaining these things from ATCC.
