Subject: Df(2R)Px1 Hi Rachel-- Could you add the following comment or something similar to the entry for Df(2R)Px1 (FBab0002026), please? 'Complementation tests reported for Df(2R)Px1 may have used a Df(2R)Px2 stock. The Mid-America Stock Center stock 1779 and the Bloomington Stock Center stock 750, which were labeled Df(2R)Px1, were in fact Df(2R)Px2 stocks. The mix-up predates 1991.' Darin Coulson and John Roote at Cambridge discovered the problem. Thanks! Kevin
