2. Figure 1
Expression profiles of Hsp 70 protein of spermatozoa from fertile and infertile men grouped as asthenospermics and oligoasthenospermics. A protein sample from fertile group was applied onto lane 1 in each assay performed and its value was taken as 100% arbitrarily to compare with other samples (A). The blots were stripped and subsequently reprobed with an α-tubulin antibody for normalization of loading (B). The Western blot picture of α-tubulin is representative blots from random patients in the study.
