Answer
Basis of differentiation | Cross-reactivity | Speciftify |
Definition | Is the ability of an antibody to bind to multiple antigens | Is the ability of an antibody to bind specifically to a single antigen or a group of closely related antigens |
Occurrence | Occurs when an antibody recognizes epitopes shared among different antigens | Occurs when an antibody recognizes an epitope on a specific antigen |
Effect | May lead to false positives or nonspecific binding in assays | Ensures accurate results in assays by minimizing nonspecific bindings |
