Immunohistochemistry analysis of S100 beta showing staining in the cytoplasm and nucleus of paraffin-embedded mouse brain tissue (right) compared to a negative control without primary antibody (left). To expose target proteins, antigen retrieval was performed using 10 mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with S100 beta (16H24L21) ABfinity Rabbit Monoclonal Antibody (701340) diluted in 3% BSA-PBS at a dilution of 1:20 overnight at 4°C in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using a HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

This antibody is predicted to react with non-human primate and rabbit based on sequence homology.
ABfinity™ recombinant antibodies are rabbit monoclonal antibodies, unmatched for producing superior results. ABfinity™ antibodies are developed by immunizing animals, screening for functionality, cloning the immunogen-specific antibody genes into high-level mammalian expression vectors, produced on a large scale, and purified with Protein A.
ABfinity™ monoclonal antibodies resemble rabbit monoclonals isolated from serum or produced by hybridomas, but demonstrate greater specificity and sensitivity. Because ABfinity™ recombinant antibodies are derived from cloned DNA sequences of the heavy and light antibody chains, they are not susceptible to cell-line drift or lot-to-lot variation, thus allowing for peak specificity and performance.
Intact IgG appears on a non-reducing gel as ~150 kDa band and upon reduction generating a ~25 kDa light chain band and a ~50 kDa heavy chain.
S100 calcium binding protein B protein family. S100B is present in the cytoplasm and nucleus of various cell types. It plays a role in intracellular Ca2+-dependent functions through regulation of calcium homeostasis, and transduction of intracellular Ca2+ signals. S100B is involved in the regulation of the cell cycle, differentiation, and apoptosis. It also is involved in cell motility through modulation of membrane–cytoskeletal interactions. In humans, the S100B gene is present at the 21q22 locus.
