In Vitro Production of IFN-β by Transduced TS/A Clones

Cell clone	Transduced retroviral vector	IFN production (IU/ml)
TS/A parental	None	<2
TS/A-LXSN	LXSN	<2
TS/A-IFN-β-2	LMuIFN-βSN	64
TS/A-IFN-β-4	LMuIFN-βSN	128
TS/A-IFN-β-12	LMuIFN-βSN	512
TS/A-IFN-β-8	LMuIFN-βSN	1024
TS/A-IFN-β-6	LMuIFN-βSN	2048
TS/A-IFN-β-10	LMuIFN-βSN	2048

Supernatants were harvested and titrated for IFN-β production as described in Materials and Methods.
