Testicular IGFBP-5 levels, measured by Western blotting. Upper: Western blotting of IGFBP-5 and actin in the testes of males homozygous for the deletion allele (Pappa2 KO/KO; KO) or the intact conditional allele (Pappa2 fl/fl; fl). Lower: Ratio of the intensity of the IGFBP-5 band to that of the actin band, standardized by dividing an individual sample’s ratio by the mean ratio of all samples on the same blot. Horizontal lines represent the means for each group
