Growth protocol
NCI60Adherent; RNA harvesting protocol for adherent cells Media used: RPMI 1640 500 ml FBS 25 ml -use the DTP serum if possible, from Bio Whittaker, not heat inactivated 200 mM Glutamine 5 ml 1 flask = ~15 x 106 cells yields ~ 100 ugr RNA. Grow 10 flasks. Cells: start from growing cells from Frederick (not frozen). Started before at passage #8-12. Do not use past passage 20. Growth schedule prior to harvest: Grow cells to ~80 confluencey. Trypsinize cells with 5 ml try-EDTA per T162, 15 min., 370C. Pipet up and down several times w 10 ml pipet to get good dispersment of cells. Count cells. Pass cells to as many flasks as there are cells for. When passing cells, combine flasks into a single pool. Pass 1x106 cells into each T162 w 30 ml media. Repeat growth cycle until 10 flasks are available. Refeed Refeed cells the day prior to harvest without harvesting). Draw off media (wo cells). Add back media, 30 ml per T162. Add back to T-162âs. 37 deg C, ON Harvest Target confluency 80% # of flasks = 10 Draw off media from 1st flask. Lyse cells in 15 ml lysis buffer (w 10 ul fresh BME per ml). Scrape cells. Draw off media from 2nd flask. Pipet lysis buffer from flask 1 into flask 2. Repeat lysis with up to 4 T162âs. Pipet into 50 ml tube. Repeat w next set of 4 flasks. When done, vortex 10 sec.. Draw lysate thru a 20 guage needle 12xâs. Freeze at ö800C. Purify using Quiagen Midi Kit. Use a maximun of 100 x 106 cells per column. More will not bind to the column.
