    Applications

    These cells constitutively express the simian virus 40 (SV40) large T antigen, and clone 17 was selected specifically for its high transfectability.  293T/17細(xì)胞,人胚腎細(xì)胞

    Storage Conditionsliquid nitrogen vapor phase
    Derivation

    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.

    Antigen Expression

    SV40 T antigen

    Genes Expressed

    SV40 T antigen

    Comments

    293T/17 cells were cotransfected with the pCRIPenv- and the pCRIPgag-2 vectors to obtain the ANJOU 65 (see ATCC CRL-11269) cell line. ANJOU 65 cells were cotransfected with the pCRIPgag-2 and pGPT2E vectors to obtain the BOSC 23 (see ATCC CRL-11270) ecotropic envelope-expression packaging cell line. ANJOU 65 cells were also cotransfected with the pCRIPAMgag vector along with a plasmid expressing the gpt resistance gene to obtain the Bing (see ATCC CRL-11554)amphotropic envelope-expression packaging cell line.

    Complete Growth MediumThe base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.    
    SubculturingVolumes are given for a 75 cm2 flask. Increase or decrease the amount of dissociation medium needed proportionally for culture vessels of other sizes.
    1. Remove and discard culture medium.

    2. Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum that contains trypsin inhibitor.

    3. Add 2.0 to 3.0 mL of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes).

      Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37°C to facilitate dispersal.

    4. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting.

    5. Add appropriate aliquots of the cell suspension to new culture vessels.

    6. Incubate cultures at 37°C.

    Subc*tion Ratio: A subc*tion ratio of 1:4 to 1:8 is recommended

    Medium Renewal: Every 2 to 3 days

    Cryopreservation

    Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO

    Storage temperature: liquid nitrogen vapor phase

    Culture Conditions

    Temperature: 37°C          
    Atmosphere: air, 95%; carbon dioxide (CO2), 5%
