Adaptación de una técnica de inmunosorbencia (ELISA) a la detección del virus del rayado fino del maíz en su insecto vector

Abstract

Se desarrolló un sistema de inmunoabsorbencia con ligados enzimáticos (ELISA) para la detección del virus del rayado fino de maíz (VRF) en su insecto vector Dalbulus maidis. La optimización del método incluyó la purificación de la IgG anti-VRF por cromatografía de intercambio iónico y la determinación de concentraciones críticas del conjugado enzima-IgG del detergente Tween 20 y la albúmina bovina. Bajo las condiciones experimentales descritas en este trabajo, la prueba permitió la detección del antígeno viral en insectos individuales a concentraciones menores de 1.0 ng.

An enzyme-linked immunosorbent assay (ELISA) was adapted for detection of maize rayado fino virus (RFV) in its insect vector Dalbulus maidis. Optimization of experimental conditions for the assay included the use of anti-RFV immunoglobulin G (IgG) purified by ion exchange chromatography and the determination of critical concentrations of the enzyme-IgG conjugate, Tween 20 and bovine serum albumen. Under the experimental conditions described in this work, it was possible to detect viral antigens in individual leafhoppers at concentrations of less than 1.0 ng.
