Please refer to the specific buffer information in the hardcopy of datasheet or the lot-specific COA.

Reconstitution Reconstitute in sterile water for a stock solution. Adjust the volume of sterile water so that, after reconstitution, the final stock concentration matches the value indicated on the product label or datasheet.

RECONSTITUTION PROTOCOL
1. Allow the product to be reconstituted and the reconstitution diluent to reach room temperature.
2. Tap or briefly centrifuge the product vial before opening to dislodge any lyophilized material that may be dispersed on the wall or cap of the vial.
3. Use the diluent and stock concentration recommended in the product datasheet. If preparing a stock concentration higher than recommended, contact Technical Service.
4. After adding the diluent, re-cap the vial and invert gently by hand or place on a slow rocking platform to allow the reconstitution diluent to coat all the surfaces inside the vial. Note: Do not mix by vortexing or by pipetting the material up and down.
5. Allow the vial to sit at room temperature with gentle agitation for at least 15 minutes before aliquotting or using.
6. Store the reconstituted material in single use aliquots in polypropylene or siliconized tubes. Aliquots of 10 μL or larger are recommended.
Shipping In general, proteins are provided as lyophilized powder/frozen liquid. They are shipped out with dry ice/blue ice unless customers require otherwise.
Stability and Storage Use a manual defrost freezer and avoid repeated freeze thaw cycles. Store at 2 to 8°C for frequent use. Store at -20 to -80°C for twelve months from the date of receipt.
Alternate NamesSemaphorin-4A, Semaphorin-B, Sema B, Sema4a, Semab, SemB
Background

Semaphorin-4A is a ~83 kDa protein. Cell surface receptor for PLXNB1, PLXNB2, PLXNB3 and PLXND1 that plays an important role in cell-cell signaling. Regulates glutamatergic and GABAergic synapse development. Promotes the development of inhibitory synapses in a PLXNB1-dependent manner and promotes the development of excitatory synapses in a PLXNB2-dependent manner. Plays a role in priming antigen-specific T-cells, promotes differentiation of Th1 T-helper cells, and thereby contributes to adaptive immunity. Promotes phosphorylation of TIMD2.
