Hello,
I am working on lncRNAs, one of my lncRNAs is INHBA-AS1 and I design intron spanning primer for it. In real time PCR I just have primer dimer with melt lower than 70, I decreased primers concentration and increased cDNA concentration and also increased annealing tempreture but I just have primer dimer.this is my primer's image from NCBI. what should I do?
