Protocol for GAL1 promoter induction.

I have a fusion construct under the control of GAL1 promoter and try to
induce its production. By using the antiserum against the N-terminal of
the fusion product, we should be able to detect the fusion after
induction by galatose. But, there is nothing detectable.

I grew the yeast containing the fusion construct in 2% glucose/leu-
media overnight, the next morning I took 50 ul of the overnight culture
into 2 ml of 2% galactose/leu- media and grew it overnight again. Is
there anything wrong with this induction scheme?

Thanks in advance for help.
