5' and 3' rapid amplification of cDNA ends (RACE) of Rffl-lnc1.
Figures are generally photos, graphs and static images that would be represented in traditional pdf publications.
(A) Primer design for 5’RACE and 3’RACE. P1 and P2 were designed for 5’RACE. P3 and P4 were designed for 3’RACE. (B) 5’RACE PCR amplification. Lane 1 shows the PCR products by using P1 and UPM to amplify 5’RACE cDNA. Lane 2 and 3 show the distinct 5’RACE PCR products a, b, c and d by using P2 and UPS to amplify the diluted PCR product from lane 1 (nested PCR). (C) 3’RACE PCR amplification. Lane 4 shows PCR products by using P3 and UPM to amplify 3’RACE cDNA. Lane 5 shows the distinct 3’RACE PCR product by using P4 and UPS to amplify the diluted PCR product from lane 4 (nested PCR). (D) The schematic showing four Rffl-lnc1 transcripts. The full length sequences of Rffl-lnc1 were obtained by in-fusion cloning of RACE products for sequencing.
