  • 产品描述:

    The Sema4d was produced as a fusion protein with a C-terminal mFc-tag in mammalian cells. Its expression region corresponds to the amino acid 24-733 of the mouse Sema4d protein. This recombinant Sema4d protein is an active protein and its activity has been validated through the ELISA. In the functional ELISA, this mouse Sema4d protein can bind to the Pepinemab, with the EC50 of 4.878-7.446 ng/ml. The purity of this Sema4d protein is greater than 95% measured by SDS-PAGE. On the gel, this Sema4d protein migrated to the molecular weight band of about 117 kDa. It contains less endotoxin, <1.0 EU/ug determined by the LAL method. And it is available now.

    Sema4d is a transmembrane homodimer involved in the inactivation of platelets, stimulation of angiogenesis, and regulation of bone formation. It also possesses immune regulatory activity. Studies have shown that Sema4d is hyper-expressed in some malignancies and facilitates tumor growth and angiogenesis.

  • 功能:
    Cell surface receptor for PLXNB1 and PLXNB2 that plays an important role in cell-cell signaling. Regulates GABAergic synapse development. Promotes the development of inhibitory synapses in a PLXNB1-dependent manner. Modulates the complexity and arborization of developing neurites in hippocampal neurons by activating PLXNB1 and interaction with PLXNB1 mediates activation of RHOA. Promotes the migration of cerebellar granule cells. Plays a role in the immune system; induces B-cells to aggregate and improves their viability (in vitro). Induces endothelial cell migration through the activation of PTK2B/PYK2, SRC, and the phosphatidylinositol 3-kinase-AKT pathway.
