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. |
| Age | fetus |
| Applications | Individual clones were isolated and tested for the ability to produce high titer beta galactosidase expressing retroviruses. The amphotropic envelope expressing construct, pCripAMgag- which contains mutations in the gag region, lacks the packaging site, and replaces the 3' LTR, was transfected into Anjou 65 cells along with a plasmid expressing the gp resistance gene. Bing is an amphotropic envelope-expressing packaging line derived from the 293T cell line. |
| Storage Conditions | liquid nitrogen vapor phase |
| Disclosure | This material is cited in a US or other Patent and may not be used to infringe the claims. Depending on the wishes of the Depositor, ATCC may be required to inform the Patent Depositor of the party to which the material was furnished. This material may not have been produced or characterized by ATCC. |
| Derivation | Bing is an amphotropic envelope-expressing packaging line derived from the 293T cell line. The 293T/17 cell line is a derivative of the 293T (293tsA1609neo) cell line. 293T is a highly transfectable derivative of the 293 cell line into which the temperature sensitive gene for SV40 T-antigen was inserted. 293T cells were cloned and the clones tested with the pBND and pZAP vectors to obtain a line capable of producing high titers of infectious retrovirus, 293T/17 (see ATCC CRL-11268). 293T/17 cells were cotransfected with the pCRIPenv- and the pCRIPgag-2 vectors to obtain the ANJOU 65 (see ATCC CRL-11269) cell line. The amphotropic envelope expressing construct, pCripAMgag- which contains mutations in the gag region, lacks the packaging site, and replaces the 3' LTR, was transfected into Anjou 65 cells along with a plasmid expressing the gp resistance gene. Individual clones were isolated and tested for the ability to produce high titer beta galactosidase expressing retroviruses. One clone produced betagal retrovirus with a titer in excess of 10(6)/ml following transfection with pBND8. Two rounds of limiting dilution subcloning were performed subsequently, giving rise to the CAK8, or Bing cell line. |
