2. Figure 1
(A) miRNA Ct expression values classified as Determined, Undetermined, or Unreliable. The miRNAs fraction of each category present or absent in all individuals has been indicated by stripes. (B) Hierarchical clustering of the 10 individuals based on the miRNA Ct values obtained. Samples are represented by column (n = 10) and assays by row (n = 768).

3. Supplemental Figure 1
Electrophoretic gel of PCR products corresponding to (A) PRM1 amplification. Ladder: molecular marker (0.1–1 kb). C+ = Genomic DNA as a positive control (422b). S01-S10 = Sperm cDNAs showing an intronless product obtained from RT (331b). C− = negative controls (RT-PCR without RNA and PRM1 PCR without cDNA). (B) GAPDH amplification. Ladder: molecular marker (0.1–1kb). C+ = Genomic DNA as a positive control (332b). S01-S10 = Sperm cDNAs showing an intronless product obtained from RT (228b). C− = negative controls (RT-PCR without RNA and GAPDH PCR without cDNA). (C) CD45 amplification. Ladder: molecular marker (0.1–1kb). C+ = Complementary DNA obtained from peripheral blood lymphocytes as a positive control (179b). S01-S10 = Sperm cDNAs showing the absence of CD45 marker. C− = negative controls (RT-PCR without RNA and CD45 PCR without cDNA).

Electrophoretic analysis results of the sperm RNA samples using the Agilent 2100 Bioanalyzer. (A) Small-RNA chip (RNAs ranging from 4 to 150 nt). (B) Nano-RNA chip (RNAs ranging from 25 to 200 nt). The last electropherogram (in A and B) was obtained from Jurkatt cells RNA (somatic cell control).
