Detecting b-gal in cultured cells ?

[simmenlab at animal.ufl.edu]

Hello:
                
              I am transfecting cells in culture with a b-gal expression 
vector.  I was wondering if it was possible to detect b-gal expression without 
preparing cell extracts.  I just want to know if the transfection worked or 
did not work.  If anyone has any experience with this please let me know.  
Thank you very much!
