Anti-SCN4B antibody produced in rabbit，100UL，HPA017293-100UL，Sigma

General description

SCN4B (Sodium channel, voltage-gated, type IV, β subunit) is a 250kDa voltage-gated sodium (Na_v) channel of the Na_v channel signaling complex. It consists of a cleaved signal sequence, an extracellular Ig-like fold, a transmembrane segment, and a short intracellular C-terminal tail. It is expressed in neurons in the brain, spinal cord, and some sensory neurons.

Immunogen

Sodium channel subunit beta-4 precursor recombinant protein epitope signature tag (PrEST)

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies^® protocols and other useful information.

Biochem/physiol Actions

SCN4B (Sodium channel, voltage-gated, type IV, β subunit) plays a key role in cellular communication. It influences the transmembrane voltage gradient for proper transmission of cellular messages over long distances. It is a multifunctional single-transmembrane glycoprotein associated with several sodium channel activities such as maintenance of the gating properties of voltage-gated ion channels, regulation of Na_v channel trafficking as well as its expression levels and facilitating cell adhesion and migration. It also plays an important role in the protein-protein interactions. Mutation in SCN4B causes familial atrial fibrillation and congenital long-QT syndrome.

Features and Benefits

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
