Cell React
Source:
A 651-bp fragment containing the ttgR gene was amplified by PCR from P. putida DOT-T1E chromosomal DNA, and cloned in E. coli expression vector. TtgR protein was over-expressed and purified.
Prep. Method:
TtgR protein was further purified by size exclusion chromatography using a Sephacryl HR-200 column (Amersham Biosciences). Eluted fractions of TtgR were pooled, concentrated, and dialyzed against the buffer.

Syringe React
Prep. Method:
All chemicals were manipulated in glass vessels and effector samples were neither degassed nor filtered, to avoid evaporation or nonspecific binding. Analyses were carried out using 5% DMSO to facilitate solubilization.
