Plasmid map of pGEX-B72-P. pGEX-B72-P was derived from plasmid pGEX-4T-3 which contains the pBR322 origin. B7-2: coding sequence for 224-aa extracellular domain of human B7-2 costimulatory molecule; phaP: coding sequence of PHA associated protein phasin (PhaP); Amp: ampicillin resistance gene; Lac I: coding sequence of Lac operon DNA-binding transcriptional repressor.
