Question

What type of molecule is used in a protein microarray to measure protein expression?
A) cDNA
B) mRNA
C) Single-stranded DNA
D) Antibodies

Accepted Answer

Antibodies are used in protein microarrays to measure protein expression. They are immobilized on a solid support and used to capture specific proteins from a sample. This allows for the simultaneous detection and quantification of multiple proteins in a sample.
