		Comments:	The 20B8 cell line was established by transfection of HKB-11 cells (ATCC CRL-12568) with pCIS25DTR expression vector coding for a B-domain deleted (BDD) FVIII. This cell line can be used for high productivity of B-domain deleted Factor VIII.
	
	
		Propagation: 20B8細胞ATCC complete growth medium: The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
	
	
		Atmosphere: air, 95%; carbon dioxide (CO2), 5%
	
	
		Temperature: 37.0°C
	
	
		Subculturing:	Protocol:
	
	
		Remove and discard culture medium.
	
	
		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.
	
	
		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.
	
	
		Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.
	
	
		Add appropriate aliquots of the cell suspension to new culture vessels.
	
	
		Incubate cultures at 37?C.
	
	
		
	
	
		Medium Renewal: Two to three times weekly
	
	
		Preservation:	Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO
	
	
		Storage temperature: liquid nitrogen vapor phase
