test for equal

Hello all,
I have 2 groups of samples and I example some gene expressions in each
sample. The goal is to find genes that have different expression levels
between and genes that have same expression levels between group. For
the first one I used t-test and p<0.05. I think for these genes that
have p >0.05 can't be called equal because the p value control the
positive not the false negative. Type II error seems right but it
requires expected difference that we don't know. Can I use the
difference from the data or the difference has to be known priori to
the test. Is there any other way to test equal (H0: unequal. H1: equal)
only use existing data?
Thanks in advance
Bin
