Human VASA Antibody

Detection of Human VASA by Western Blot.

Western blot shows lysates of human testis tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human VASA Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2030) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for VASA at approximately 85 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

VASA in Human Testis.

VASA was detected in paraffin-embedded sections of human testis using Goat Anti-Human VASA Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2030) at 10 µg/mL overnight at 4 °C. Before incubation with the primary antibody tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Detection of Mouse VASA by Immunohistochemistry

Immuno-staining on control and PMSG treated ovarian sections.A-C: Immunostaining with anti-PCNA antibody. Note minimal PCNA staining in control OSE. Increased staining is observed after PMSG treatment in both the OSE cells and the oocytes of PF (B-&C). Inset B’ is magnified image of the PF located in the OSE. At places, granulosa cells were also positive for PCNA (arrowhead). D-F: Immunostaining with anti-OCT-4 antibody in control (D) and 7D PMSG treated (E&F) ovarian sections. OCT-4 is localized in the ooplasm in control, while in 7D PMSD treated, positive staining was observed in ooplasm as well as in the nucleus of few oocytes (arrowhead) in PFs. G: Immunostaining with anti-human VASA antibody that cross-reacts with mouse MVH. MVH is distinctly localized in the ooplasm of PF and at places was also observed in a ‘germ cell nest’ (G’, arrow). At places some oocytes of primordial follicles in cohorts appeared connected without intervening granulosa cell (arrowhead) H-J: SCP-3 is localized in PF oocytes present in close vicinity of multilayer OSE.
