We also performed immunoprecipitation (IP) experiments using two anti–cadherin 1 antibodies (clones ECCD-2 and 36) and whole cell extracts prepared from the uninfected tumor cells or from the tumor cells infected with RCASBP-dnE-cad or RCASBP-Bcl-xL. The gene discussed is BCL2L1; the disease is neoplasm.
