A co-worker of mine is looking for expression of B gal (beta gal) in animal
skin tissue samples (monkey or mouse). He would like to know if this can be
done in formalin fixed paraffin samples. He had done it before in frozen
ones. We are interested to know if we can see the expression of B gal in
paraffin samples. We appreciate all the help we can get. Thank you for your
cooperation.
