You need BSA in the mix to prevent enzyme denaturation on the borosilicate
capiliaries. I don't have a light cycler but do have something similar IE
a Rapidcycler. The borosilicate will also absorb Mg2+ so you need a conc
of min 3mM. 4mM should be OK for a standard reaction.
I should say that I have no afiliation with the folowin company BUT:::::
DNamp.com do a nice enzyme mix (I don't think they can call it a light
cycler mix) that has a range of premix concs with BSA. I'm sure Duncan
will be alng in a sec. :-)

PS I'm back with the forcasts after breaking my news again. :-)
