The purpose of BSA is to stabilize the polymerase. Some suggest that it is
not allways needed. The neccesity of BSA depends on the type of polymerase
used.  I highly recommend the molecular grade BSA (normally provided when
purchasing restriction enzymes). Other preparations often contain DNAses
and inhibitors.

Hope this helps,


Doing PCR?
Have you got some good, working primers???
