Biosafety Icon BSL 1

ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services. It is your responsibility to understand the hazards associated with the material per your organization’s policies and procedures as well as any other applicable regulations as enforced by your local or national agencies.

Detailed product information


Restriction digests of the clone give the following sizes (kb): BamHI--7.4; EcoRI--4.4, 3.0; HindIII--4.4, 3.0; PstI--5.0, 0.96, 0.36, 0.24; HincII--4.0, 3.4.
To resolve some of the TaqI alleles with similar fragment sizes, the depositor suggests using a 0.9% agarose gel and allowing bromphenol blue migration of 15 cm.
The St14 sequence family appears to be dispersed over a 570 - 600 kb region of Xq28.
The TaqI B2 allele (4.1 + 1.4) is almost exclusively associated with the 3.4 kb allele from the VNTR polymorphism.
This probe also detects polymorphisms with MspI, DdeI, BglI, and Tth111I.
St14-1 detects genomic fragments of the following approximate sizes (kb): BamHI--3.6; HindIII--10.0; TaqI--3.9; EcoRI--10.0.
