Identification of alternatively spliced ANK1 cDNA transcripts in M. longissimus thoracis et lumborum. a. Two transcripts differing in size by approximately 341 bp were identified. b. Two purified transcript variants of ANK1 gene. Amplified segments of cDNA from two individuals may be seen in lanes 1 and 2 (amplified using an internal primer from known exon 2); DNA ladder (GeneRuler™ 100-5000 bp, Fermentas) is in lane 3.
