TABLE 1.

Effect of cell type and time p.i. on viral factory costaining for cUb

Virus strain	Cell type	Factory morphologya	% of infected cells with factories that costained with cUb at the following time (h) p.i.b:
			12	24	36	48
T3DN	CV-1	Globular	90 ± 2	90 ± 5	91 ± 5	88 ± 3
	HeLa	Globular	NDc	49 ± 18	ND	85 ± 6
	L929	Globular	ND	85 ± 5	ND	83 ± 3
T1L	CV-1	Filamentous	6 ± 1	8 ± 3	9 ± 2	8 ± 3
	HeLa	Filamentous	ND	2 ± 2	ND	14 ± 6
	L929	Filamentous	ND	4 ± 3	ND	3 ± 1

^aFor CV-1 cells, in which counts were performed, filamentous indicates that ≥96% of cells displayed obvious filaments, and globular indicates that ≤1% of cells displayed obvious filaments.

^bResults are means of three determinations ± standard deviations; the MOI was 5 PFU/cell. Factories were identified by staining with anti-μ2 or anti-μNS serum. cUb was identified by staining with MAb FK2.

^cND, not determined.
