The envelope protein (Env) of the Jaagsiekte sheep retrovirus (JSRV) is known to be a unique oncoprotein responsible for inducing ovine pulmonary adenocarcinoma (OPA). The objective of this study was to prepare a specific monoclonal antibody (mAb) against the JSRV Env protein using bioinformatic analysis. According to the structure and epitope prediction results of JSRV Env, the JSRV-Env
572-615
antigen was prepared via peptide synthesis (amino acid sequence 572-615, denoted as JSRV-Env
572-615
). BALB/c mice were immunized to prepare the anti-JSRV-Env
572-615
mAb.
Spleen
cells were fused with
SP2
/0 myeloma cells after being screened by indirect ELISA and cloned by limiting dilution. The specificity of mAb was evaluated by western blot analysis and immunohistochemistry assays. Western blot results showed that the JSRV Env protein was able to bind to mAb with high specificity. Immunohistochemistry assays demonstrated that the mAb was able to recognize JSRV Env in adenomatous hyperplasia of the lung. Furthermore, JSRV was detected in peripheral blood leukocytes during the pre-clinical period of OPA in 2 of the 25 sheep using this newly synthesized mAb. Therefore, this mAb may be a useful tool for the detection of JSRV in sheep.

Monoclonal antibodies (MAbs) were developed for a rapid and efficient screening procedure to detect cultures of Vibrio cholerae serogroup O1.
Spleen
cells of BALB/c mice previously immunized with an attenuated control strain of V. cholerae were fused with mouse myeloma cell line
SP2
/0. An enzyme-linked immunosorbent assay (ELISA) was used to test cultural hybridoma secretions of two MAbs against 120 strains of V. cholerae O1, 38 strains of V. cholerae non-O1, 15 strains of other Vibrio spp., and 20 strains of other bacterial species. Results of tests using both MAbs were identical. The MAbs successfully detected all of the confirmed serotype O1 strains. Three additional V. cholerae strains that agglutinated antisera and the saline control were considered serologically inconclusive. Of these, one was detected as positive for V. cholerae by both MAbs. The MAbs gave no false-positive reactions when tested against the confirmed non-O1 strains, other Vibrio spp., and other bacterial species. Use of this ELISA will enhance the speed and accuracy needed for detecting V. cholerae O1 cultures.
