Fig. 1.
β-Gal activities of positive clones isolated by the yeast 2-hybrid system.
The 16 clones correspond to those genes described in Table 1. Samples 1-7, 8-12, and 13-15 belong to groups A, B, and C, respectively. Sample 16 is a positive control for the β-Gal assay using a full-length Gal4 expression plasmid (pCL1; Clontech), and sample 17 is a negative control (empty vector-transformed) for the assay.
