Which of the following statements regarding ELISAs is TRUE?
A) They are not quantitative.
B) They require large amounts of serum.
C) The antibody label is a fluorescent molecule.
D) They can be used to detect antibody or antigen.
E) They involve the use of membrane filters.

Accepted Answer

ELISAs can be used to detect either antibodies or antigens. They are often used in diagnostic tests for infectious diseases and autoimmune disorders. The amount of antigen or antibody present can be determined using ELISAs, making them quantitative. ELISAs do not typically require large amounts of serum, and the antibody label can be a variety of molecules, not just fluorescent ones. There is no involvement of membrane filters in the ELISA technique.
