Table 2 Expressed target protein

Line No.	Total soluble protein (mg/g fresh weight)	Content of HBsAg (ng/g fresh weight)	HBsAg/TSP (1/1000000)
1#	16.0	45	3
2#	15.5	24	2
3#	12.6	21	2
4#	13.1	90	7
CK	13.7	-

Note: 1#, 2#, 3# and 4# were four different lines of transgenic cherry tomatillo with normal phenotype, and these materials were all leaves of transgenic plants in the condition of tissue culture; CK was leaf of a non-transformed tomatillo in tissue culture.
