Identification of double-gene recon by PCR.
M: DNA marker; 1: double-gene recon 1 BDNF mRNA amplification product (788 bp); 2: double-gene recon 1 CNTF mRNA amplification product (611 bp); 3: double-gene recon 2 BDNF mRNA amplification product (774 bp); 4: double-gene recon 2 CNTF mRNA amplification product (597 bp). Recombinant plasmid pIRES-BDNF was digested by Xho I and Mlu I, and two fragments, a 774-bp-long target gene BDNF fragment and an approximately 1.6-kb-long pIRES vector fragment, were acquired, confirming the product was recombinant plasmid pIRES-BDNF. BDNF: Brain-derived neurotrophic factor. CNTF: ciliary neurotrophic factor.
