This study produced and evaluated MAbs to the expressed coat protein of CiLV-C thus providing an inexhaustible and uniform supply of reagents for use in any of three diagnostic methods described. This is the first report of the generation of MAbs against the expressed coat protein of CiLV-C. Since the MAbs in this study were used for capturing the virus, a critical step in the methods, variations in the sensitivity and specificity encountered from newly produced PAbs used as detecting antibodies will likely be tolerated with minimal impact on the serological assays.
