Abstract
Many studies that aim to characterize the proteome require the production of pure protein in a high-throughput format. We have developed a system for high-throughput subcloning, protein expression and purification that is simple, fast, and inexpensive. We utilized ligation-independent cloning with a custom-designed vector and developed an expression screen to test multiple parameters for optimal protein production in E. coli. A 96-well format purification protocol that produced microgram quantities of pure protein was also developed. Keywords: high-throughput • protein purification • ligation-independent cloning
