Arrays of protein-capture agents useful for the simultaneous detection of
a plurality of proteins which are the expression products, or fragments thereof,
of a cell or population of cells in an organism are provided. A variety of antibody
arrays, in particular, are described. Methods of both making and using the arrays
of protein-capture agents are also disclosed. The invention arrays are particularly
useful for various proteomics applications including assessing patterns of protein
expression and modification in cells.
