Testing in progress
A DNA sequence encoding the human SCN2B (O60939) (Met1-Ala159) was expressed, fused with the Fc region of human IgG1 at the C-terminus.
Predicted N Terminal
The recombinant human SCN2B /Fc is a disulfide-linked homodimer. The reduced monomer comprises 371 amino acids and has a predicted molecular mass of 42.2 kDa. The apparent molecular mass of the protein is approximately 53-57 kDa in SDS-PAGE under reducing conditions.
Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us
for any concerns or special requirements.Please refer to the specific buffer information in the hard copy of CoA.
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Stability & Storage
Samples are stable for up to twelve months from date of receipt at -70℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
SCN2B plays a key role in the assembly, expression, and functional modulation of the heterotrimeric complex of the sodium channel. Voltage-gated sodium channels (NaV) are composed of one pore-forming alpha-subunit, which may be associated with either one or more beta-subunits. Alpha-subunits are composed for four homologous domains, each of which contains six transmembrane segments.They are responsible for action potential initiation and propagation in excitable cells, including nerve, muscle, and neuroendocrine cell types. SCN2B causes an increase in the plasma membrane surface area and in its folding into microvilli. SCN2B also interacts with TNR and may play a crucial role in clustering and regulation of activity of sodium channels at nodes of ranvier.
