Santa Cruz Biotechnology rabbit polyclonal anti wave2 antibody

Immunofluorescence analysis was performed to assess the spatial co-localization of SKAP2 and <t>WAVE2</t> during oocyte meiotic maturation. As shown in Fig. 8, SKAP2 exhibited predominant localization in the proximal cortical region of oocytes from metaphase I (MI) to metaphase II (MII) stages. Furthermore, SKAP2-WAVE2 co-localization displayed stage-specific patterns: (1) at the MI stage, concentrated asymmetrically at the cell membrane periphery; (2) during anaphase I (AI), distributed along the emergent cell membrane; and (3) at the MII stage, localized specifically at the intercellular junction between daughter cells. All experiments were repeated at least three times

Techniques Used: Immunofluorescence, Membrane

To investigate SKAP2-mediated regulation of WAVE2 membrane dynamics, immunofluorescence analysis was performed in control and SKAP2 knockdown oocytes. As shown in Fig. 10, in control groups, WAVE2 exhibited stable expression and cortical localization throughout meiotic progression, with stage-specific co-localization patterns with F-actin: (1) asymmetric cortical clustering at metaphase I (MI), (2) peripheral membrane distribution during anaphase I (AI), and (3) intercellular junction accumulation at metaphase II (MII). However, SKAP2 depletion significantly reduced WAVE2 expression levels and disrupted its co-localization with F-actin across all meiotic stages. All experiments were repeated at least three times. Data are shown as the mean ± standard deviation. The Student’s t-test was used for data analysis. * P < 0.05, ** P < 0.01, *** P < 0.001, and **** P < 0.0001

Ordinary one-way ANOVA with Dunnett’s multiple comparisons test: ∗∗∗∗P < 0.0001 (WT CRISPR Ctrl <> NHSL3 CRISPR KO-1; WT CRISPR Ctrl <> NHSL3 CRISPR KO-2).

Techniques: Transfection, Control, Binding Assay, Knock-Out, Activity Assay, CRISPR, Expressing

Figure 5. (A). Rac1-dependent activation of WAVE2 is impaired in the absence of Gai2. Western blot analysis of Gαi2, p-Wave2 in PC3 cells constitutively overexpressing Rac1, with (+) or without (−) Gαi2 siRNA. Total WAVE2 and α-Tubulin were used as loading controls. (B). Ratios of optical densities (mean ± SEM) of Phosho-Wave2/total Wave2 after different treatments (data from three replicate experiments).
