tissue of origin: Renal cell line: A498 age: 52 Sex: F epithelial: yes ploidy: 3n, Triploid (69) p53 mutation: WT doubling time: 66.8 contributing institute: National Cancer Institute, NIH reference: JNCI 51: 1417-1423,1973
Treatment protocol
No treatment
Growth protocol
Cells grown in RPMI 1640 with 5% FBS (Bio Whittaker, not heat inactivated) and 1% L-glutamine. Cells not grown past 80% confluencey for attached cells, or 0,5 x 10-6 cells for suspended. Trypsinize (for attached cells) cells with 5 ml trypsin-EDTA per T162, for 15 min., at 370C. Spin down suspended cells, and resuspend in ~3ml growth media. Count cells. Pass 1x10-6 cells into new T162’s w 30 ml media. Repeat growth cycle until desired amount of cells are available. Cells are not grown past passage 20.
Extracted molecule
total RNA
Extraction protocol
Growth schedule prior to harvest: Grow cells to ~80 confluencey. Re-feed cells the day prior to harvest. Draw off media from attached cells, or spin down suspended cells. Rinse cells with ~10 ml 1x PBS. Purify using Quiagen Midi Kit (Cat # 75144) per instructions. In brief, lyse cells in 15 ml lysis buffer (w 10 ul fresh BME per ml) per 4 T162s. Scrape (attached) cells. Pipet into a 50 ml tube. Repeat with the next set of 4 flasks. When done, vortex 10 sec.. Draw lysate thru a 20 guage needle 12x’s. Freeze lysate at -80 deg C. Use a maximum of 100 x 10-6 cells per column.
