SdpII-specific antibodies identify different splice variants of the protein in a number of different cell lines and tissues. a, Lysates from HeLa cells transfected with the full-length proteins SdpI, SdpII-s, SdpII-l, or vector alone were separated on SDS-PAGE, transferred to nitrocellulose, and probed with either tag-specific antibodies (anti-Xpress) or affinity-purified antibodies raised against SdpI (antiserum 2703) and SdpII (antisera P339 and 3685). b, Postnuclear supernatants from various rat tissues and cellular extracts were resolved by SDS-PAGE, transferred to nitrocellulose, and subjected to Western blot analysis. SdpII-specific antibodies recognized a 65-kD band predominantly in the PC12 cell line and heart, and, less prominent, in testis and additional cellular extracts. In addition, a protein of an electrophoretic mobility of 52 kD was detected in all tissues analyzed, which appears to be enriched in brain, kidney, testis, and skeletal muscle.
