Can we use less BigDye terminator reagent mix?

We use the PCR buffer from Qiagen Taq polymerase to dilute the ready reaction
mix.  You always have buffer left when all of the polymerase is used, so we keep
the rest of the buffer for diluting sequencing reactions.

 mix :
 90 ul 10x buffer
 210 ul water
 100 ul Big dye reaction mix

 We use 4 ul of this mix for sequencing ( 1/2 volume reactions), 0,5 ul primer,
 2,5 ul PCR produkt, 3 ul water.  After precipitation, add 2 ul loading buffer
and load everything.  Works fine for us...
