Producción de antígenos y estandarización de un ELISA casero indirecto para la detección de anticuerpos contra Anaplasma marginale

Serologic tests are important for the detection of specific antibodies against infectious agents. Commercial indirect ELISA are costly and usually as effective as in-house ELISAs. In the present work, it was prepared a batch of Anaplasma marginale crude antigen from infected blood, and tested it against official positive and negative serum controls and compared with an old batch of antigen. The new antigen batch showed an efficiency similar to the old batch. The sensitivity of the test was comparable between the new and old batches. Both, new and old antigen lots are being used at an excess. The new antigen lot is large enough to run thousands of tests at a more affordable price than commercial kits.
