Treatment of macrophages with S100B does not reduce cell viability as indicated by cell morphology and acid phosphatase assay.

<p>Images to show BMDM untreated (A) and treated with 2 μM S100B for 24 h (B) and RAW 264.7 untreated (C) and treated with 2 μM S100B for 24 h (D). Scale bars = 50 μM. Acid phosphatase cell viability assay on RAW 264.7 untreated or treated with 2μM or 5 μM S100B for 24 h (E) and on BMDM (F). No significant difference in viability following treatment with 2μM S100B for 24 h. Triton (0.1%) and DMSO (10%) as positive controls for the assay. Error bars indicate SEM n = 6.
