I need help locating control tissue for the Alpha Fetoprotein antibody.  I would like to have a heptatocelluar carcinoma sample to use for a positive control, but we rarely see those tumors.  We have had a couple of needle bxs come through, but the sample size is insufficient to use as control material.  Can anyone help? P.S.  We have never seen a yolk sac tumor!!!!
