Description |
The recombinant human semaphorin-4D (SEMA4D) is an active protein generated by the expression of the gene fragment encoding amino acids 22-734 of the human SEMA4D in mammalian cells. The 10xHis tag is fused to the C-terminal of this protein. Its purity is over 90% measured by SDS-PAGE. On the gel, this protein migrated to the molecular weight band of approximately 85 kDa. It contains less than 1.0 EU/ug endotoxin determined by the LAL method. In the functional ELISA, this recombinant SEMA4D protein can bind Pepinemab and the EC50 is 4.035-5.743 ng/mL. SEMA4D, also known as CD100, has diverse effects on immunologic processes, including immune cell proliferation, differentiation, activation, and migration, through binding to its specific membrane receptors CD72, PLXNB1, and PLXNB2. It is also involved in the control of neurogenesis, angiogenesis, and tumor progression. |

Form |
Lyophilized powder Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand. |
Buffer | Lyophilized from a 0.2 μm filtered 20 mM Tris-HCl, 0.5 M NaCl, 6% Trehalose, pH 8.0 |
Reconstitution | We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference. |
Troubleshooting and FAQs |
Protein FAQs |
Storage Condition | Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles. |
Shelf Life | The shelf life is related to many factors, storage state, buffer ingredients, storage temperature
and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C. |
Lead Time | 3-7 business days |
Notes | Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week. |

Function |
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.
