Invitrogen™ Human SCN4B (aa 50-152) Control Fragment Recombinant Protein

Product Code. 30205407

Brand: Invitrogen™ RP90488

Description

Recombinant Protein

Highest antigen sequence indentity to the following orthologs: Mouse (74%), Rat (74%). This recombinant protein control fragment may be used for blocking experiments with the corresponding antibody, PA5-53579 (PA5-53579. In IHC/ICC and WB experiments, we recommend a 100x molar excess of the protein fragment control based on the concentration and the molecular weight. Pre-incubate the antibody-protein control fragment mixture for 30 min at room temperature.

The SCN4B protein modulates channel gating kinetics. Causes negative shifts in the voltage dependence of activation of certain alpha sodium channels, but does not affect the voltage dependence of inactivation. The protein has been found to be expressed at a high level in dorsal root ganglia, at a lower level in brain, spinal cord, skeletal muscle and heart. Defects in SCN4B are the cause of long QT syndrome type 10 (LQT10) [MIM:611819]. Long QT syndromes are heart disorders characterized by a prolonged QT interval on the ECG and polymorphic ventricular arrhythmias. They cause syncope and sudden death in response to exercise or emotional stress. They can present with a sentinel event of sudden cardiac death in infancy.
