Depositor Comments

Plasmid pEGFP-puro was constructed by PCR amplification of PuroR coding sequences from pPur (Clontech Laboratories, Palo Alto CA, USA) using upstream
and downstream
primers, digestion of the PCR product with BglII andBamHI, and ligation into BglII/BamHI digested pEGFP-C1 (Clontech Laboratories).

To construct a fusion protein containing both EGFP and PuroR sequences, PuroR coding sequences were ligated into an existing expression cassette for EGFP. The resulting fusion protein was designated EGFP-puro and is contained in plasmid pEGFP-puro. This plasmid contains the strong human cytomegalovirus immediate early promoter (Phcmv), the EGFP puro open reading frame, and the simian virus 40 (SV40) polyadenylation signal. The EGFP-puro protein contains the first 245 amino acids of EGFP. The C-terminal five amino acids of EGFP were deleted and replaced by four linker-encoded amino acids, followed by the complete 200-amino-acid PuroR sequence. The C-terminus is formed by 11 amino acids encoded by vector sequences. The resulting fusion protein (EGFP-puro) confers both green fluorescence and resistance to puromycin when expressed in mammalian cells.
