S100B in WM‑115 Human Cell Line. S100B was detected in immersion fixed WM‑115 human malignant melanoma cell line (positive staining) and MCF‑7 human breast cancer cell line (negative staining) using Mouse Anti-Human S100B Monoclonal Antibody (Catalog # MAB18204) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm and nuclei. Staining was performed using our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Background: S100B

S100B belongs to the S100 subgroup of the EF-hand family of Ca2+ binding proteins. It is a homodimer that is expressed primarily in the brain by astrocytes, oligodendrocytes and Schwann cells. S100B has multiple intracellular functions, but can also be secreted from cells to exert extracellular functions. Some of the extracellular functions of S100B may be mediated by RAGE (receptor for advanced glycation end products). Blood levels of S100B can be used to monitor the extent of brain injury and malignant melanoma.
