Methods for anylysising target protein using PYP proteins and PYP mutants therefor

摘要

The present invention relates to a protein expression or quantitative analysis method using PYP protein and PYP protein for protein expression or quantitative analysis. The protein expression or quantitative analysis method according to the present invention can quickly and accurately recognize the expression of a target protein, The purity can be measured. Further, the present invention does not cause any problems even when a tag system is used in combination, and can be applied not only to prokaryotes but also to eukaryotic protein expression systems. Because of this property, it has the utmost usefulness for ultra-rapid protein expression screening. Therefore, the protein expression or quantitative analysis method of the present invention can be usefully utilized in related studies of proteins.
