Selective Quantification of Protein Biomarkers with Immunoassays
Quick fact
Immunoassays can detect and quantify protein biomarkers at concentrations as low as a few picograms per milliliter — equivalent to finding one drop of a substance in a swimming pool.
Why this is interesting
Imagine finding a single needle in a haystack—but the needle is a protein floating in a drop of blood. How can we tell it apart from millions of other proteins?
