产品描述说明：Sema4D (Semaphorin-4D) is a cell surface receptor for PLXN1B and PLXNB2 that plays an important role in cell-cell signaling. Sema4D promotes reorganization of the actin cytoskeleton and plays a role in axonal growth cone guidance in the developing central nervous system. Sema4D regulates dendrite and axon branching and morphogenesis. It promotes the migration of cerebellar granule cells and of endothelial cells. In the immune system Sema4D induces B-cells to aggregate and improves their viability (in vitro). Sema4D also promotes signaling via SRC and PTK2B/PYK2, which then mediates activation of phosphatidylinositol 3-kinase and of the AKT1 signaling cascade [taken from the Universal Protein Resource (UniProt) www.uniprot.org/uniprot/Q92854]. 品牌简介： 世界排名前十的抗体生产商，以优质的兔多克隆抗体闻名，所有抗体都经过一系列实验技术的检验，如：ELISA，WB，IP，ChIP，PLA（邻近连接技术），IHC和ICC等；不断生产出新的抗体，产品不仅针对新兴领域的热门蛋白，也包括一直以来缺少高质量检测抗体的经典蛋白。目前已拥有针对2300种目标蛋白而生产出来的近7000种一抗，同时也可提供针对来自27个种属的免疫球蛋白的二抗；抗体定制方面有40年的经验。
