TABLE 2.

Relative amounts of exogenous ³⁵S-sBPP and endogenous BPP bound to B- and C-capsids in nuclear preparations of SCMV-infected cells

Virus particle	BPP		Triplex	BPP/triplex
	35Sa (A)	Westernb (B)	Westernc (C)	35S (A/C)	Ratiod	Western (B/C)	Ratioe
B-capsid	2,710	1,177	22,791	0.12	12:1	0.05	1:6
C-capsid	51	1,920	6,042	0.01		0.32

^aPhosphorimaging measurements were made from CBB-stained dried gel. The samples in the gel were the same as those shown after electrotransfer to Immobilon membranes in Fig. 4A; measurements were from corresponding lanes 6 (B-capsids) and 9 (C-capsids). The numbers are in units of photostimulated luminescence (PSL; proportional to the amount of radioactivity present) and were corrected for background. 

^bPSL of BPP bands on Immobilon membrane shown in Fig. 4B, lanes 6 (B-capsids) and 9 (C-capsids). 

^cPSL of mCP bands on Immobilon membrane shown in Fig. 4B, lanes 6 (B-capsids) and 9 (C-capsids). mCP is one of the two triplex proteins and is present in a fixed copy number in capsids (15); it was used to normalize the ³⁵S-sBPP measurements to the relative amounts of B- and C-capsids. 

^dCalculated as (A/C for B-capsids) divided by (A/C for C-capsids). 

^eCalculated as (B/C for B-capsids) divided by (B/C for C-capsids).
