Sensitivity of ELISA lies in the range

A. 1 - 5 ng/l

B. 1 - 10 ng/l

C. 5 - 50 ng/l

D. 15 - 20 ng/l

Answer: Option B

Solution(By Examveda Team)

The sensitivity of ELISA lies in the range of 1 - 10 ng/l.
The typical detection range for an ELISA is 0.1 to 1 fmole or 0.01 ng to 0.1 ng, with sensitivity dependent upon the particular characteristics of the antibody-antigen interaction.
ELISAs tend to be the most sensitive immunoassays due to the binding characteristics of the antibodies and the amplification or different read-out systems used.
