Immunofluorescence localization of VDR in human ejaculated spermatozoa. A: VDR Immunolocalization; B: Sperm cells incubated without the primary Ab were utilized as negative control. C: Sperm cells incubated replacing the anti-VDR Ab by normal rabbit serum were utilized as negative control. The pictures shown are representative examples of experiments that were performed at least three times with reproducible results.
