Figure 1. Detection of mRNA for kisspeptin receptor in human cardiomyocytes.

Figure 1

(A) Expression of kisspeptin receptor mRNA in samples (n = 3) of human myometrium (Lanes 1–3), used as a control to confirm the specificity of PCR primers as this is a tissue in which the receptor protein has been previously identified. The integrity of the samples was confirmed by detection of the β-actin product of the expected size, 353 bp, indicating integrity of cDNA and absence of gDNA. PCR product size was determined using a 100 bp DNA ladder (Lane 4) (B) Expression of kisspeptin receptor mRNA (expected size 198 bp) in cDNA from human isolated cardiomyocyte samples (n = 3, lanes 3–5). β-Actin control (Lane 2) acted as a positive control and the absence of cDNA (Lane 1) served as a negative control with a 100 bp DNA ladder (Lane 6).
