Understanding ELISA Testing (Enzyme-Linked Immunosorbent Assay)

Lock-and-Key Concept

Antibodies bind only to specific antigens through complementary structures.

This specificity makes ELISA highly accurate.

Factors Affecting Binding

  • pH
  • Temperature
  • Antigen concentration
  • Antibody concentration
  • Incubation time

Poor control of these factors can affect test accuracy.
