Biosafety Level 1

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.

Shipping Information Distributed: freeze-dried
Restriction digests of the clone give the following sizes (kb): PstI--3.0, 1.1, 1.1; EcoRI--5.2; HindIII--5.2. The clone contains two copies of the insert.
The insert contains the following restriction sites (approximate kb from the 5' end): PvuII--0.06, 0.82; SphI--0.35; NcoI--0.38; SmaI--0.79.
A single gel purification of the PCR generated probe is necessary since flanking regions will co-amplify with the gene specific sequence. Failure to do so often results in high backgrounds and false positives with clinical E. coli strains.
A hybridization probe may be generated using the following vector specific PCR primers: modified T3 = 5'-CCCCTCACTAAAGGGAACAAAAGCTG-3' and modified T7 = 5'-CGCGTAATACGACTCACTATAGGGCGAA-3'.
The suggested PCR generated probe encodes the last 617bp of the aph(3')-IIa gene plus 290bp of the bleomycin resistance gene from Tn5. A better probe for the aph(3')-IIa gene would be the 383bp PstI/NcoI fragment.
