| 再構成 | 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. |
| 発送 | In general, proteins are provided as lyophilized powder/frozen liquid. They are shipped out with dry ice/blue ice unless customers require otherwise. |
| 安定性と保存 | 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. |

| 背景 | CD81 antigen is a ~25 kDa protein. Structural component of specialized membrane microdomains known as tetraspanin-enriched microdomains (TERMs), which act as platforms for receptor clustering and signaling. Essential for trafficking and compartmentalization of CD19 receptor on the surface of activated B cells. Upon initial encounter with microbial pathogens, enables the assembly of CD19-CR2/CD21 and B cell receptor (BCR) complexes at signaling TERMs, lowering the threshold dose of antigen required to trigger B cell clonal expansion and antibody production. In T cells, facilitates the localization of CD247/CD3 zeta at antigen-induced synapses with B cells, providing for costimulation and polarization toward T helper type 2 phenotype. Present in MHC class II compartments, may also play a role in antigen presentation. 1. Shoham, T. et al. (2006) Molecular and cellular biology 26, 1373-85. PMID: 16449649 2. van Zelm, MC. et al.
