| Description |
The C-terminally hFc-tagged human semaphorin-4D (SEMA4D) is an active recombinant protein expressed in mammalian cells. Its expression region corresponds to amino acids 22-734 of the human SEMA4D. The purity of this SEMA4D protein is greater than 95% measured by SDS-PAGE. It migrated to the molecular weight band of about 120 kDa on the gel. Its endotoxin is less than 1.0 EU/ug determined by the LAL method. In a functional ELISA, this recombinant SEMA4D protein can bind biotinylated Pepinemab. The EC50 is 1.005-1.776 ng/mL. SEMA4D, also known as CD100, is involved in immune regulation, bone formation, platelet inactivation, angiogenesis stimulation, and cancer bone metastasis. |
| Purity | Greater than 95% as determined by SDS-PAGE. |

| 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 PBS, 6% Trehalose, pH 7.4 |
| 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. |

| 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.
