Verification of pGL3-ENGFAP and PCA19-ENGFAP plasmids by gel electrophoresis, according to the size (bp) of excised fragments. (A) Excised fragments of pGL3-ENGFAP were detected by gel electrophoresis. Lanes 1–6, double digestion with MluI and XhoI; lane 7, GeneRuler™ DNA Ladder mix (10,000 bp); and lanes 8–13, double digestion with PvuI and PvuII. (B) Excised fragments of PCA19-ENGFAP were detected by gel electrophoresis. Lanes 1–6, double digestion with EcoRI and XbaI; lane 7, GeneRuler™ DNA Ladder Mix; and lanes 8–13, digestion with PstI. GFAP, glial fibrillary acidic protein.
