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


This plasmid was constructed by linkering XbaI/Sau3A fragments from the Y chromosome with EcoRI and inserting into the EcoRI site of pJB8. There are EcoRI sites in the insert so the intact insert cannot be released by an EcoRI digest.
Restriction digests of the clone give the following sizes (kb): BamHI--11.0; BamHI/XbaI--10.0, 0.94; HindIII--6.4, 4.7; SalI--12.5; EcoRI--5.4, 4.2, 0.66, 0.52.
IMPORTANT: To prevent amplification of a rearranged and/or deleted cosmid, we recommend streaking on LB + amp plates at 30C and picking small colonies for liquid culture.
The single-copy BamHI/XbaI fragment has been sequenced.
The single-copy probe (0.9 kb) of the insert can be excised with a BamHI/XbaI double digest. It must be separated from highly repeated flanking sequence by gel electrophoresis.
At low stringency (2X SSC, 42C) TaqI detects 4 Y-specific bands which are independently polymorphic and several other Y-specific constant bands.

Not detected
