Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.
Size (kb): 3.5069999694824220
Vector: pdeltablue (plasmid)
Promoters: Promoter lambda PL
Construct size (kb): 3.506999969482422
Features: insert detection: lacZ'
promoter: lambda PL
vector permitting visual detection of recombinants
Restriction digests of the clone give the following sizes (kb): BglI--1.75 (doublet); EcoRI--3.5; PstI--2.1, 1.45.
Restriction digests of the plasmid give the following sizes (kb): BamHI--3.507; BglI--1.784, 1.723; PstI--2.072, 1.435; PvuI--2.063, 1.444; PvuII--2.852, 0.655; SacI--3.257, 0.25.
Inserts can be cloned into the vector using a filled-in NcoI site and a MCS restriction site matching the 3' end of the insert. The vector supplies the AUG initiator codon.
The insert to be cloned should have a phosphorylated 5' blunt end with the first base corresponding to the first base of the first codon.
Expression vector producing proteins with the one additional N-terminal methionine. A modified lacZ' allows blue/white screening of colonies.
Constructed from pfXblue (ATCC 77333)
by deletion of lambda cII and coagulation factor Xa protease recognition sequences (nt 824-943).
The order of the major features of the plasmid is: pMB1 ori - ampR - lambdaPL promoter - NcoI/MCS/HindIII/modified lacZ'.
