Fig. 3From: pXST, a novel vector for TA cloning and blunt-end cloningThe lethality testing of pXST and pXST-R. a Vector pXST was transformed into E.coli DB3.1 strain. DH5α strain harboring pXST was grown on the plates with (b) or without (c) IPTG respectively. d Vector pXST-R was transformed into DH5α and the strain survived in LB-plate with IPTGBack to article page
