However, the only Abs we have gotten to work are those from BD and Phoenix Flow, both of which are equivalent. We however, need to do fixation/perm as well as DNAse tx. We have the best results using EtoH as per the original Tough and Sprent paper. It seems this part may be optional if the cells are kept fix/perm long enough(?) I am not aware of any other clones that even work in this system (the Caltag Ab did not work here nor in immunohistochem). Another issue is the inordinate expense of the BrdU Abs. It would seem that the BD Ab, at $400 per 50ug (i.e at $8,000/mg) is the world's most expensive Ab. It would be so nice to get hold of a clone that I could grow in the lab. Anyone who could help with this would be most appreciated. Cristoph, if you get any private replies I would greatly appreciate if you could forward them to me.
