GPB-1 antibodies were produced by cloning full-length gpb-1 cDNA into pGEX-6P2 (Promega), expressing GST-GPB-1 and purifying it from inclusion bodies. The protein was gel purified and injected into a rabbit (Eurogentec). The resulting antibodies were strip-purified against GST- GPB-1, using 0.1 M glycine pH 2.5 as an elution buffer. Affinity-purified antibodies were then dialyzed against PBS and kept at -20°C in 50% glycerol at 0.2 mg/ml.
