引用 | ジャーナル: Proc Natl Acad Sci U S A / 年: 2019 タイトル: Microfluidic protein isolation and sample preparation for high-resolution cryo-EM. 著者: Claudio Schmidli / Stefan Albiez / Luca Rima / Ricardo Righetto / Inayatulla Mohammed / Paolo Oliva / Lubomir Kovacik / Henning Stahlberg / Thomas Braun / 要旨: High-resolution structural information is essential to understand protein function. Protein-structure determination needs a considerable amount of protein, which can be challenging to produce, often ...High-resolution structural information is essential to understand protein function. Protein-structure determination needs a considerable amount of protein, which can be challenging to produce, often involving harsh and lengthy procedures. In contrast, the several thousand to a few million protein particles required for structure determination by cryogenic electron microscopy (cryo-EM) can be provided by miniaturized systems. Here, we present a microfluidic method for the rapid isolation of a target protein and its direct preparation for cryo-EM. Less than 1 μL of cell lysate is required as starting material to solve the atomic structure of the untagged, endogenous human 20S proteasome. Our work paves the way for high-throughput structure determination of proteins from minimal amounts of cell lysate and opens more opportunities for the isolation of sensitive, endogenous protein complexes. | |||||||||
