Cell React
Source:
The open reading frame encoding the full-length Escherichia coli Rho protein was PCR amplified and cloned. The protein was overexpressed in E. coli strain BL21 (pLysS).
Purity:
99%
Prep. Method:
The protein was twice purified over a POROS-HS column (Perseptive Biosystems) then further purified with two successive Sephacryl S-300 (Amersham) sizing columns. The protein at this stage was more than 99% pure as judged by SDS-PAGE.
