General description

pT7-FLAG-2 is a 4.8 kb E . coli expression vector used for cloning and cytoplasmic expression of a properly inserted open reading frame as a C-terminal FLAG® fusion protein containing the FLAG epitope (DYKDDDDK). The promoter region of the very strong phage T7 promoter drives transcription of ORFFLAG fusion constructs. This vector requires the use of E. coli cells containing a source of the T7 polymerase, such as BL21(DE3)T1R cells, Catalog Number B2935.

The C-terminal FLAG fusion protein may be detected using Monoclonal ANTI-FLAG?M2, Catalog Number
F3165, and purified using the ANTI-FLAG M2 Affinity Gel, Catalog Number A2220.

N348I in HIV-1 reverse transcriptase (RT) confers resistance to zidovudine (AZT) and nevirapine. Biochemical studies demonstrated that N348I indirectly increases AZT resistance by decreasing the frequency of secondary ribonuclease H (RNase H) cleavages that reduce the RNA/DNA duplex length of
