Background
Partnering with the transmembrane protein CNTNAP2, the Contactin-2/CNTN2 protein plays a crucial role in organizing axonal domains at nodes of Ranvier. Its collaborative action involves the maintenance of voltage-gated potassium channels specifically at the juxtaparanodal region. This dynamic interplay highlights Contactin-2's pivotal contribution to the intricate molecular architecture that underlies the proper functioning of nodes of Ranvier, essential for the efficient propagation of nerve impulses along myelinated axons.
Verified Bioactivity
Measured in a cell proliferation assay using SH-SY5Y cells. The ED50 for this effect is ≤1.421 μg/mL, corresponding to a specific activity is ≥703.729 units/mg.

Product Properties
Lyophilized powder
1.Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
2.Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4, 8% trehalose.
Please refer to the lot-specific COA for specific buffer information.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
