Description
For more on the ELISA technique visit the University of Wisconsin Plant Pathology Lab website.A commercial lab such as Agdia, www.agdia.com, has a variety of services that Maria must sort through. She may send a plant sample into the lab or request a test kit that she could use at her greenhouse operation. Assuming Maria elects to send in a plant sample, an ornamental screening test would be prescribed: Agdia states that this is a starting point to identify pathogens. Maria would need to follow the instructions for submitting a sample, which typically require overnight shipping charges to ensure that plant tissue remains in good condition.The Enzyme-Linked Immuno Sorbent Assay (ELISA) testing protocol is a technique that was developed in the late 1970’s to detect viruses.
