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 By similarity. 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 excercise or emotional stress. They can present with a sentinel event of sudden cardiac death in infancy. -

Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 25 kDa
Observed band size: 37 kDa why is the actual band size different from the predicted?
Additional bands at: 20 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 8 minutes
Further characterization on this product is underway. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above. SCN4B contains at least three potential glycosylation sites (SwissProt), which may explain its migration at a higher molecular weight than predicted. The primary sequence contains a 30-residue signal sequence at the N-terminus. The band around 20-kDa in human skeletal muscle may be the unglycosylated form of the target protein. -
Immunocytochemistry/ Immunofluorescence - Anti-SCN4B antibody (ab80539)ICC/IF image of ab80539 stained PC12 cells. The cells were 4% formaldehyde (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab80539, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899 Dylight 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
