Restrictions: These cells are distributed for research purposes only. The Scott and White Clinic releases the line subject to the following: 1) The cells or products derived from them must not be sold or used for commercial purposes. Nor can the cells be distributed to third parties for purpose of sale, or producing for sale, cells or their products. Commercial interests are the exclusive property of the Scott and White Clinic. 2) Any proposed commercial use of these cells or products produced by them must first be negotiated with the Scott and White Clinic, 2401 S. 31 Street, Temple, Texas 76508. Telephone (817) 774-2432
Isolation: Isolation date: 1978
Tumorigenic: Yes
Antigen Expression: Blood Type A; Rh +
Cytogenetic Analysis: near triploid; range = 67 to 75

Ethnicity: Caucasian
Comments: The SW 1990 line was established in 1978 from a spleen metastasis of a grade II pancreatic adenocarcinoma deriving from the exocrine pancreas. 
The cells have a reported plating efficiency of 29%.
Propagation: ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Leibovitz's L-15 Medium, Catalog No. 30-2008. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Temperature: 37.0°C 
Atmosphere: air, ****
Subculturing: Protocol:
  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.

      Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:4 is recommended 
      Medium Renewal: 2 to 3 times per week
Preservation: Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO 
Storage temperature: liquid nitrogen vapor phase
Doubling Time: 64 hrs
Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2008
recommended serum:ATCC 30-2020
