Functional bioactivity has been validated through rigorous quality control assays, confirming its suitability for demanding research applications.
High quality, high purity and low endotoxin recombinant Recombinant Human NCAM-1/CD56 Protein (RPCB1904), tested reactivity in HEK293 cells and has been validated in SDS-PAGE.100% guaranteed.
Endotoxin:
< 0.01 EU/μg of the protein by LAL method
Purity:
≥ 95 % as determined by SDS-PAGE.
Formulation:
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
Bio-Activity:
Measured by the ability of the immobilized protein to support the adhesion of Neuro‑2A Human neuroblastoma cells. The ED50 for this effect is 1.8-7.2 μg/mL.
Reconstitution:
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
Storage:
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
Neural Cell Adhesion Molecule 1 (NCAM-1), a multifunctional member of the immunoglobulin superfamily, is expressed on the surface of neurons, glia, skeletal muscle, and natural killer cells. NCAM-1 has been implicated as having a role in cell-cell adhesion, involved in development of the nervous system, and for cells involved in the expansion of T cells and dendritic cells which play an important role in immune surveillance.
Recombinant Human NCAM-1/CD56 Protein was determined by SDS-PAGE under reducing conditions with Coomassie Blue.
immobilized protein to support the adhesion of Neuro‑2A Human neuroblastoma cells. The ED50 for this effect is 1.8-7.2 μg/mL.
