Extracellular domains of CNTNAP2 and CNTN2.
A, SDS-PAGE analysis of purified recombinant CNTNAP2 (lane 1) and CNTN2 (lane 3). Markers (in kDa) are shown in lane 2. B, size exclusion chromatography of CNTNAP2; C, size exclusion chromatography of CNTN2; D, size exclusion chromatography of standards (2,000, 200, 66, 29, and 12.4 kDa) and resulting calibration line. Samples and standards were run in triplicate. The average elution volume (EVave) and S.D. value are shown. The apparent molecular masses (Mapp) are indicated and reflect large versus small species.
