Product details

While the standard is the same as the one provided in the corresponding SimpleStep ELISA Kit, it cannot be treated as the consumable provided with our SimpleStep ELISA Kit due to differences in its concentration calibration.

Abcam guarantee that this protein standard is suitable for use in a sandwich ELISA. Individual results may vary due to differences in technique, laboratory equipment, buffers, and other experimental factors. The detection range provided for this protein standard is based on initial sandwich ELISA validation data.

The protein concentration is the concentration after validation on our sandwich ELISA platform. This Standard protein is guaranteed to work with our Capture and Detector antibodies in sELISA. Please contact our Scientific Support team to know which antibody pair is suitable for this protein.

Supplementary information

S100 beta also known as protein S100 is part of the S100 family of proteins characterized by their calcium-binding properties. The S100 beta protein has an approximate molecular mass of 10.7 kDa. This protein is mainly expressed in astrocytes a type of glial cell in the central nervous system. It acts as a marker for astrocytes and is prominently used in astrocyte immunohistochemistry. Additionally it serves as a valuable marker for identifying and studying astrocyte markers because it can highlight the presence of these cells in various contexts.
Biological function summary

The S100 beta protein participates in several intracellular and extracellular activities influencing cell proliferation and differentiation. It forms dimers and sometimes assembles into larger complexes mediated by the binding of calcium ions which alters its functional state. Within the nervous system S100 beta modulates the dynamics between neurons and glial cells affecting processes such as cell survival and neurite outgrowth. This dual role in both supporting and inhibiting various cellular actions highlights its importance in maintaining neural homeostasis.

Pathways

S100 beta engages in signaling pathways related to inflammation and stress responses. It works within the MAPK and NF-kB pathways playing roles in cellular responses to oxidative stress. These pathways involve interactions with other proteins like p53 which S100 beta can modulate to influence apoptosis. The regulatory properties of S100 beta in these pathways link it with broader networks affecting cell fate decisions under pathological and physiological conditions.

S100 beta is associated with neurodegenerative diseases and cancer. Elevated levels of S100 beta are often found in Alzheimer's disease where it interacts with proteins like amyloid-beta contributing to neuroinflammation and neurotoxicity. In cancer particularly malignant melanoma S100 beta levels serve as a biomarker for tumor progression. Its interactions with p53 and other regulatory proteins highlight its involvement in oncogenic processes emphasizing its potential as a target for therapeutic intervention in these diseases.

General info

Function

Small zinc- and- and calcium-binding protein that is highly expressed in astrocytes and constitutes one of the most abundant soluble proteins in brain (PubMed : 20950652, PubMed : 6487634). Weakly binds calcium but binds zinc very tightly-distinct binding sites with different affinities exist for both ions on each monomer (PubMed : 20950652, PubMed : 6487634). Physiological concentrations of potassium ion antagonize the binding of both divalent cations, especially affecting high-affinity calcium-binding sites (By similarity). Acts as a neurotrophic factor that promotes astrocytosis and axonal proliferation (By similarity). Involved in innervation of thermogenic adipose tissue by acting as an adipocyte-derived neurotrophic factor that promotes sympathetic innervation of adipose tissue (By similarity). Binds to and initiates the activation of STK38 by releasing autoinhibitory intramolecular interactions within the kinase (By similarity). Interaction with AGER after myocardial infarction may play a role in myocyte apoptosis by activating ERK1/2 and p53/TP53 signaling (By similarity). Could assist ATAD3A cytoplasmic processing, preventing aggregation and favoring mitochondrial localization (PubMed : 20351179). May mediate calcium-dependent regulation on many physiological processes by interacting with other proteins, such as TPR-containing proteins, and modulating their activity (PubMed : 22399290).
