Restriction Map and Multiple Cloning Site (MCS) of pEGFP Vector. Unique restriction sites are in bold. The Xba I
sites in the MCS can be used together to excise the EGFP gene.
pEGFP carries a red-shifted variant of wild-type green fluorescent protein (GFP) which has been
optimized for brighter fluorescence and higher expression in mammalian cells. (Excitation maximum
= 488 nm; emission maximum = 507 nm.) pEGFP encodes the GFPmut1 variant (1) which contains
the double-amino-acid substitution of Phe-64 to Leu and Ser-65 to Thr. The coding sequence of the
EGFP gene contains more than 190 silent base changes which correspond to human codon-usage
preferences (2). Upstream sequences flanking EGFP have been converted to a Kozak consensus
translation initiation site (3) to further increase the translation efficiency in eukaryotic cells.
The EGFP gene was cloned between the two MCS of the pUC19 derivative pPD16.43 (4). The EGFPcoding sequence is flanked by separate MCS at the 5' and 3' ends, so the EGFP gene can be easilyexcised from pEGFP. Alternatively, the EGFP coding sequence can be amplified by PCR. The EGFPgene was inserted in frame with the lacZ initiation codon from pUC19 so that a EGFP fusion proteinis expressed from the lac promoter in E. coli. Note, however, that if you excise the EGFP codingsequence using a restriction site in the 5' MCS, the resulting fragment will encode the native (i.e.,non-fusion) EGFP protein. The pUC backbone of EGFP provides a high-copy-number origin ofreplication and an ampicillin resistance gene for propagation and selection in E. coli.
