Figure 1From: Reverse transcription quantitative real-time polymerase chain reaction reference genes in the spared nerve injury model of neuropathic pain: validation and literature searchAnalysis of reference gene stability. Assessment of reference gene stability, in the ipsilateral dorsal horn (A) and L4-L5 dorsal root ganglia (B) in the rat spared nerve injury model using M-value (left) from the geNorm algorithm and coefficient of variation (CV) (right). Candidate genes are classified from left to right by increasing order of M-value, from most to least stable. The cut-off for stability is 1 for M-value and 50% for CV (dotted line).Back to article page
