Un método eficaz para evaluar la superficie de exposición de las proteínas de la leptospirosis se describe. El método está diseñado específicamente para evitar la interrupción de la frágil membrana externa de las células de leptospira. Esta técnica requiere el empleo de varios controles negativos para evaluar la integridad de la membrana externa y la especificidad de la reacción de los anticuerpos.
