This invention relates to peptide microarrays, methods of generating peptide microarrays, and methods of identifying peptide binders using microarrays. More specifically, this invention relates to peptide microarrays, methods of generating peptide microarrays, and methods of identifying peptide binders using microarrays wherein the microarrays comprise cyclic peptides. The invention also relates to methods and compositions for detecting the formation of cyclized peptides from linear peptides on a microarray by contacting the microarray with a detectable protein. The cyclized peptides include tags that are activated upon cyclization, facilitating the detection of successful cyclization reactions. In additional aspects, the invention relates to developing fragmented peptide tags that, upon cyclization, bind to detectable proteins. Additionally, the invention relates to methods of generating linear and cyclic peptides subarrays on a microarray.

Disclosed is a method that combines high throughput and flexible nature of a cell-free protein microarray with the quantitative capability of surface plasmon resonance to detect >400 different protein interactions in <1 hour. A method of detecting interactions between a targeting agent and one or more proteins of interest is disclosed. The method includes producing a set of proteins of interest using a cell-free protein expression system; providing the set of proteins of interest on a protein microarray wherein each spot in the array comprises a protein of interest; contacting the protein microarray with a targeting agent that binds to one or more of the set of proteins of interest; and detecting the binding of the targeting agent to the set of proteins of interest using surface plasmon resonance imaging (SPRi), thereby detecting the targeting agent and one or more proteins of interest in the micro array.

Reagents and solvents used for polymer synthesis are reused or recycled rather than discarded. The outflow from each step of polymer synthesis may be collected separately in one of multiple dedicated containers. Reuse returns the outflow from a step of polymer synthesis back to an input of a polymer synthesizer for subsequent use in that same step. Recycling processes the outflow from one or more steps of polymer synthesis to restore original concentrations or purity levels for use in a later synthesis run. Quality control analysis may determine if outflow collected from a polymer synthesizer is reused or recycled. These techniques reduce reagent cost and waste quantity. These techniques may be used with phosphoramidite or enzyme-based synthesis of deoxyribonucleic acid (DNA).

The present invention relates to a method and device for manufacturing microarrays, wherein a microarray comprises a plurality of spots, for testing the interaction of biomolecules. Disclosed herein is a method for enhancing efficiency of overlay printing of spot positions on multiple slides or plates arranged in an array wherein a slide or plate order is provided by rows and columns.
