S100B is a calcium-binding protein predominantly expressed in astrocytes and Schwann cells, where it plays essential roles in regulating cell cycle progression, differentiation, and cytoskeletal dynamics. Beyond its intracellular functions, S100B is secreted into the extracellular space where it exerts concentration-dependent effects on neurons and glia, making it a widely studied marker in neuroscience research. Elevated S100B levels have been associated with various neurological conditions, including traumatic brain injury, neurodegenerative diseases, and certain malignancies, positioning this protein as both a research target and a potential clinical biomarker.
This recombinant monoclonal antibody, clone 1F9, offers researchers the consistency and reliability that comes with sequence-defined production. Unlike traditional hybridoma-derived antibodies, recombinant technology ensures that every lot performs identically, eliminating the variability that can compromise longitudinal studies or multi-site collaborations. The antibody was raised in rabbit against a synthetic peptide derived from human S100B and has been affinity-purified to deliver high specificity for your target.
Validation studies demonstrate strong performance in immunofluorescence applications, with testing conducted in U-251MG cells, a human glioblastoma line known for robust S100B expression. At dilutions ranging from 1:50 to 1:200, the antibody produces clear cytoplasmic and nuclear staining patterns consistent with the known subcellular distribution of S100B, with DAPI counterstaining confirming cellular integrity. The antibody is also validated for ELISA, providing flexibility across detection platforms.
This antibody serves as a valuable tool for researchers investigating glial biology, neuroinflammation, brain injury biomarkers, and calcium signaling pathways in the central nervous system.
