Formulation Lyophilized from sterile PBS, pH 7.4. Normally 5% trehalose and 5% mannitol are added as protectants before lyophilization.
Reconstitution Briefly centrifuge the tube before opening. Reconstitute at 0.1-0.5 mg/mL in sterile water.
Storage
It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
  • Until expiry date, -20℃ to -80℃ as lyophilized proteins.
  • 3 months, -20℃ to -80℃ under sterile conditions after reconstitution.
Shipping The product is shipped at ambient temperature. Upon receipt, store it immediately at the recommended temperature.

Background

Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1), belonging to the immunoglobulin superfamily. It is cell adhesion protein that mediates homophilic cell adhesion in a calcium-independent manner. CEACAM1is expressed incolumnar epithelial cells of the colon, T cells, granulocytes and lymphocytes. It plays a role as coinhibitory receptor in immune response, insulin action and functions also as an activator during angiogenesis. Its coinhibitory receptor function is phosphorylation- and PTPN6 -dependent, which in turn, suppress signal transduction of associated receptors by dephosphorylation of their downstream effectors. Plays a role in immune response, of T cells, natural killer (NK) and neutrophils.It inhibits cell migration and cell scattering through interaction with FLNA and interferes with the interaction of FLNA with RALA.
