PBLU
pBLU is a commercially produced bacterial plasmid that contains genes for ampicillin resistance (specifically, beta lactamase) and beta galactosidase. It is often used in conjunction with an ampicillin-susceptible E. coli strain to teach about transformation of eubacteria. It is 5,437 base pairs long. There is a multiple cloning site in the lacZ gene.
