Opis

General description

S100 gene is mapped on human chromosome 21q22.3 and codes for an acidic calcium binding protein B, which weighs 21 kDa. The gene is predominantly expressed in astrocytes, glial cells, Schwann cells and also found in adipose cells, skin, glioblastoma multiforme and melanoma. The protein is localized in extracellular space and cytoplasm.

S100B (S-100β Subunit) belongs to the S100 family of calcium-binding proteins. It is expressed in melanocytes.
S-100 is a set of small, thermolabile, highly acidic dimer proteins of approximately 20kDa which are widely distributed in different tissues. Dimeric combinations of two chains, the α-chain (93 amino acids,10.4kDa) and the β-chain (91 amino acids, 10.5kDa), form the three known subtypes of S-100: S-100ao (αα), S-100a (αβ) and S-100b (ββ).
Monoclonal Anti-S-100 (β-subunit) (mouse IgG1 isotype) is derived from the SH-B1 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse.

Immunogen

Bovine brain S-100b

Application

Monoclonal Anti-S-100 (β-Subunit) antibody produced in mouse has been used in the following:

• ELISA
• Immunofluorescence
• Immunohistochemistry
• Western blotting

Biochem/physiol Actions

Increased expression of S100 is observed in neuronal damage and thus, serves as a biomarker for detecting brain damage and also in several cancers. Also, it is highly permeable through the blood-brain barrier. The gene is known to be associated with cancer progression.

S100β participates in multiple cellular activities including cell growth, cell structure, cell-cell communication, energy metabolism, contraction, and intracellular signal transduction. In utero exposure to cocaine resulting in aberrant S100β levels is linked with neurobehavioral abnormalities and microcephaly. Fetuses with anencephaly show aberrant cell immunoreactivity. Increased levels of this protein are found in plasma of patients with brain damage. S100β is a candidate biochemical marker for spinal cord injury (SCI). Elevated expression of this protein in subpopulations of reactive astrocytes might be linked with hippocampal structural reorganization post-kainic acid (KA)-mediated neurodegeneration.

This antibody recognizes an epitope located on the β chain (i.e. in S-100a and S-100b) but not on the α chain of S-100 (i.e. in S-100a and S-100ao). In ELISA, recognition of S-100 subunit by clone SH-B1 is independent of Ca²⁺. The product does not react with other members of the EF-hand family such as, calmodulin, parvalbumin, intestinal calcium-binding protein and myosin light chain. In immunohistochemistry, the antibody detects normal and neoplastic S-100 β subunit-containing cells (e.g. Schwann cells, chondrocytes, melanocytes, and melanotic tumors) in protease-digested, formalin-fixed, paraffin-embedded tissues.

Physical form

The product is provided as ascites fluid containing 15 mM sodium azide as a preservative.

Preparation Note

For continuous use, store at 2-8 °C for up to one month. For extended storage, the solution may be frozen in working aliquots. Repeated freezing and thawing is not recommended. Storage in "frost-free" freezers is not recommended. If slight turbidity occurs upon prolonged storage, clarify by centrifugation before use.
