Gas1 in Mouse Embryo. Gas1 was detected in immersion fixed frozen sections of mouse embryo (13 d.p.c.) using Goat Anti-Mouse Gas1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2644) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to developing brain.

Background: Gas1
Gas1 (Growth Arrest Specific 1) is one of six structurally unrelated proteins that were identified by their increased expression in growth-arrested cells relative to actively proliferating cells (1, 2). Following mitogenic stimulation, Gas1 expression is transcriptionally suppressed by c-Myc as cells transit from G0 to G1 phases of the cell cycle (3, 4). Overexpression of Gas1 prevents S phase entry and DNA synthesis (5). Gas1-mediated blockade of the cell cycle is p53-dependent but does not require the transactivating domain of p53 (6). The mouse Gas1 cDNA encodes a 343 amino acid (aa) precursor that includes a 38 aa signal sequence, a 277 aa mature protein, and a 28 aa C-terminal propeptide. Gas1 contains Ala-rich and Asp-rich regions as well as an RGD sequence (5). Mature mouse and human Gas1 share 85% aa sequence identity. Mouse Gas1 is a 40 kDa GPI linked glycoprotein that is uniformly distributed on the cell surface (7). In contact inhibited vascular endothelial cells, Gas1 is induced by VE-Cadherin and VEGF expression and mediates the anti-apoptotic effect of VEGF (8). In contrast, Gas1 is induced in hippocampal neurons after NMDA exposure but functions as a pro-apoptotic effector of NMDA-mediated excitotoxicity (9). Gas1 exhibits a range of developmental effects including either promoting or inhibiting growth and differentiation of somite, limb, cerebellar, and eye tissues (10‑14). Gas1 mediates the antagonistic effect of Wnt proteins toward Shh function by binding the N-terminal region of Shh (11). The dependence of Gas1 functions on the cellular context has been addressed by suggesting that Gas1 could function as a co-receptor for GDNF family ligands (15). This speculation is supported by R&D Systems’ data that demonstrate direct binding of Gas1 to Artemin and Neurturin.

This antibody also works perfectly for immunoprecipitation (IPP). In the article of Ayala-Sarmiento et al 2016, DOI:10.1007/s00418-016-1449-0, it is noticeable that this antibody is able to immunoprecipitate both the anchored and the soluble forms of Gas1. A clear and a single band is seen in the immunoprecipitation of the cell extract and two extracellular isoforms of soluble Gas1 are present in the conditioned medium. No signal is detected in the negative control of the IPP, see Figure.
In the publication of Estudillo et al 2015: Gas1 is present in germinal niches of developing dentate gyrus and cortex. Cell and Tissue Research. It can be appreciated that the antibody gives a congruent and clear signal of GAS1 in embrionic and postnatal brain
