Abstract
Protein arrays for the parallel, in vitro screening of biomolecular activity are provided. Methods of using the protein arrays are also disclosed. On the arrays, a plurality of different proteins, such as different members of a single protein family, are immobilized on one or more organic thinfilms on the substrate surface. The protein arrays are particularly useful in drug development, proteomics, and clinical diagnostics.
Claims3
An array device comprising:
- a substrate defining a surface, and an array of discrete array-regions over the surface;
- an ordered hydrophobic-monolayer formed of alkyl-chains having alkyl-chain proximal ends which are chemisorbed or physisorbed to said surface, and opposite alkyl-chain distal ends;
- a hydrophilic-monolayer formed from hydrophilic-chains, each having a hydrophilic-chain proximal end by which each hydrophilic-chain is covalently linked to an alkyl-chain distal end, and an opposite hydrophilic-chain distal end, said ordered hydrophobic-monolayer and said hydrophilic-monolayer being effective in combination to resist non-specific protein binding;
- and,
- a plurality of protein-immobilizing groups covalently attached to a selected fraction of said hydrophilic-chains' distal ends within said array-regions,
- such that application of one or more selected proteins to selected array-regions is effective to form an array of protein-regions, each having a selected surface concentration of a selected protein carried in and displayed on said hydrophilic-monolayer, and separated from one another by border-regions effective to resist non-specific protein binding.
