Fig. 1. Screening of anti-TPG hybridomas. Of the 330 hybridomas tested, 15 are presented here. TPG activity was measured in both the supernatant (top) and bead fraction (bottom) of each IP. Incorporation of [³H]Glu into -tubulin (light-grey bars) and ß-tubulin (dark-grey bars) was measured separately for the supernatants and together for the pellets (black bars). The control (Ctl) is an IP performed with the culture medium alone. Numbering refers to hybridoma names.
