Re-make oligo

Kerry showed me an email from Sigma which says some of their recent oligos may not meet their quality control and, unfortunately, one of my oligo primers is concerned as well (primer CFF) and asking me if I'd like them to re-make the issued oligo. Have a look on my mPCR results yesterday, I can't see any problem with the C. fetus band. Regardless of this, I still decide to re-make it (it should pay nothing, after all) :P The new oligo is supposed to arrive Wednesday next week.
