Description

General description

S100B is a Ca²⁺ binding protein that is secreted by the astrocytes by an autocrine pathway to activate the release of nitric oxide. S100B may regulate the functions of microglial cells . It may also be associated with the dynamics of intermediary filaments and microtubules in glial cells . Anti-S100B antibodies are specific for S100B in humans. The gene encoding S100B is localized on human chromosome 21.

Biochem/physiol Actions

S-100 β subunit (S100B) exerts paracrine and autocrine effects on neurons and glia. At nanomolar concentrations, the encoded protein promotes neurite outgrowth and increases survival of neurons during development. S100B serves as a marker of melanocyte cytotoxicity. In addition, it also acts as a serum marker in endocrine resistant breast cancer and nonsegmental vitiligo. Decreased expression of S100B has been observed in chronic liver disease patients.

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.
