[Development of a method for rapid detection of Ebola virus antibodies and antigen]
Abstract:
Despite the wide spectrum of reliable methods for identifying Ebola virus, their performance requires highly-skilled personnel, specialized laboratories, complicated equipment, and much time. Therefore, there is a need for a method that allows a physician or a medical attendant to identify the causative agent in field or bedside tests without special equipment as soon as possible. The immunoassay involving nitrocellulose membrane immuno-filtration, by using a fixed antigen (antibodies) or their immunosols, is a tried-and-true method. The time of the analysis is 7-15 min.

Enzyme-Linked Immunosorbent Assay
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or quantified.
