"One can measure two or more signals simultaneously determined by a single feature, i.e., epitope in immunomic microarray DNA microarrays measure one response value for each gene per sample; that is, mRNA concentration produced by the gene but a single epitope can generate different response values corresponding to different epitopes in peptide–MHC chips. In case of B cell epitope, it can be recognized by different isotypes of immunoglobulins, so here, one can measure both intensity and quality of antibody response."
These few lines are from the book: http://www.springer.com/biomed/immunology/book/978-1-4939-1114-1 Chapter 3
What does measure of one response value for each gene per sample mean?
Different response value means??
how is intensity and quality both are being measured??
