Because of their marked responsiveness to induction signals, genes encoding pathogenesis-related proteins are used as markers to monitor defense gene expression in plants. To develop a non-invasive bioluminescence reporter assay system, we tested acidic PR-1 gene promoters from tobacco and Arabidopsis. These two promoters share common regulatory elements(More)
The presence of natural antibody against Thomsen-Friedenreich (TF) antigen in fresh bovine milk was demonstrated by an enzyme-linked immunosorbent assay (ELISA). The amount of the antibody against TF antigen was decreased after heat treatment, and the antibody was not detectable by ELISA in the milk after pasteurization. A small amount of the antibody was(More)
The levels of natural antibody against Thomsen-Friedenreich (TF) antigen in sera of patients with various cancers and infectious diseases were examined by an enzyme-linked immunosorbent assay (ELISA) and compared with those of healthy donors. The levels of antibody against TF antigen in sera of patients with adenocarcinomas such as gastric, pancreatic and(More)
