antibody against polyoma LT

[Tim]

Hi, I have been trying to express polyoma LT in a cell line as stable
transfectant and hope that I can subsequently use a plasmid with the
polyoma virus replication origin/enhancer as an episomal expression
vector.  Can anyone provide info on where (commercially) I can obtain an
antibody against the polyoma LT, or better, can offer such antibody.  Many
thanks!  Tim, UCSF
