Research Abstract |
We have developed "turn-on" fluorescent probes for labeling of His-tag ((His)_6), which later turned out to have some problems. The purpose of this research is the clarification and solution of these problems, to develop useful methodology for fluorescently label proteins. The main problem of our probes is the weak binding to His-tag without N-terminal primary amino group. We determined the problem is mainly due to the His-tag recognition site, a metal complex. We explored the better His-tag recognition site and identified a metal-complex, which can bind to His-tag at any position.
