5 gently agitate the vial fr abut 2 minutes. Small ice crystal shuld remain when remved frm the water bath. - Wipe the utside f the cryvial with 70% ethyl alchl n an absrbent paper, and place the cryvial under the laminar flw hd. - Aseptically transfer the semi -thawed HepaRG cell suspensin int the tube cntaining 9 ml f the pre-warmed HepaRG Thawing/Plating/General Purpse Medium 670 (resulting in a 1:10 rati f cell suspensin t ttal vlume). - Rinse ut the cryvial nce with apprximately 1 ml f the HepaRG Thawing/Plating/General Purpse Medium 670 and return the resulting suspensin t the 40 ml tube. - Centrifuge the differentiated HepaRG cell suspensin DURING 3 MIN AT 500G at rm temperature. D nt fllw hepatcyte prtcl fr centrifugatin, the HepaRG cells are smaller in size and need a lnger and faster centrifugatin. - Aspirate the supernatant. T avid aspiratin f cells, let a little vlume f medium n the pellet. - Resuspend gently the differentiated HepaRG cell pellet with HepaRG Thawing/Plating/General Purpse Medium 670 in 5 ml fr HPR116-TA08, r 7 ml fr HPR116-TA12. Dn t try t dissciate the bigger clusters. 2.2 Cell viability measurement and cunting Cell viability measurement and cell cunting are determined by trypan blue (0.05% in D-PBS 1X) exclusin test. - Transfer 900 µl f trypan blue slutin (0.05% in D-PBS 1X) in a 5 ml plystyrene rund bttm tube. - Prepare a cell cunting chamber (e.g., Nagette chamber). T prepare the cunting chamber the mirrr-like plished surface is carefully cleaned with lens paper. The cverslip is als cleaned. The cverslip is placed ver the cunting surface befre prir t putting n the cell suspensin. - Gently hmgenize the cell suspensin by manual swirling. - Dilute 100 µl f the cell suspensin in the 900 µl f trypan blue slutin at 0.05%. - Gently hmgenize the btained cell suspensin. - Intrduce with a pipette arund 100 µl f cell suspensin between mirrr-like plished surface and cverslip. The area under the cverslip fills by capillary actin. Enugh liquid shuld be intrduced s that the mirrred surface is just cvered. - Prceed t bservatin under micrscpe. Cunt living and dead cells n at least fur rws distributed thrughut the cell cunting chamber. Living cells exclude the dye, dead cells take up the dye and appear blue. If the ttal number f cells is quite different frm ne rw t anther, cunt ne r tw mre rws. Careful: Thawed differentiated HepaRG cells can frm clusters. It s necessary t cunt all the cells including thse frming the clusters. - Determine the average number f viable cells and dead cells per rw. - Determine percentage f cell viability. Number f viable cells X 100 Number f viable cells + number f dead cells - Calculate the cell cncentratin in millin cells / ml. Sample calculatin with a Nagette chamber: Number f viable cells per rw X 10 (dilutin factr in trypan blue) X 800 (parameter relating t the Nagette cell)= M cell/ml - Calculate the ttal viable cell number: Cell cncentratin in millin cells / ml X Ttal vlume f cell suspensin = ttal number f cells Differentiated HepaRG cells crypreserved Descriptin and user guide Thawing, culture and use 5/11
