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: DNA (dried). Rehydrate with TE. (amount: 200 ng)
The insert contains 2 copies of a 2.2 kb insert containing the following restriction sites, separated by approximate kb: EcoRI- 0.4- HindIII- 0.1- BglII- 0.6- PvuII- 0.2- BglII- 0.9- EcoRI.
Restriction digests of the clone give the following sizes (kb): EcoRI--2.7, 2.4, 2.4; HindIII--4.55, 2.4, 0.55; PvuII--2.4, 2.4, 1.4, 1.3; BamHI--7.5; HindIII--7.5.
The EcoRI RFLP shows significant linkage to Wiskott-Aldrich Syndrome (theta = 0.00, Z = 10.19).
The 0.9 BglII/EcoRI fragment contains a 334 bp HaeIII/Sau3A fragment within which a deletion of about 3 kb occurred during cloning.
The 334 bp HaeIII/Sau3A fragment contains 3 complete copies and a partial copy of a 26 bp repeat which includes a 10 bp perfect inverted repeat separated by 3 nt.
EcoRI gives the best separation of alleles on 0.8% agarose gels. A stringency of 0.5 X SSC, 64 C was used routinely.
