1. A method for parallel analysis of a plurality of in vitro transcription/translation reactions, said method comprising:
- carrying out said plurality of in vitro transcription/translation reactions in a plurality of reaction mixtures in wells of a multiwell plate to generate a plurality of reaction products, wherein each non-control reaction mixture comprises cell-free protein expression reagents and at least one nucleic acid template;
spotting said plurality of reaction mixtures including reaction products onto a substrate wherein the substrate is optionally coated, wherein said reaction products bind directly to said substrate or said coated substrate, wherein said substrate comprises a membrane or a glass slide and wherein said spotting is carried out without use of a separation step that provides information about molecular weights of reaction products and without an intervening purification step; and
detecting said plurality of in vitro transcription/translation reaction products bound to said substrate.

Abstract
Methods, compositions, and kits for the cell-free production and analysis of proteins are provided. The invention allows for the production of proteins from prokaryotic sequences or eukaryotic sequences, including human cDNAs using PCR and IVT methods and detecting the proteins through fluorescence or immunoblot techniques. This invention can be used to identify optimized PCR and WT conditions, codon usages and mutations. The methods are readily automated and can be used for high throughput analysis of protein expression levels, interactions, and functional states.
