**CDr10** (Compound of Designation red 10) is microglia selective probe, and stains both primary microglia and mouse cell line BV2 cells. **CDr10a** is with acetyl group and CDr10b is with chloroacetyl group, which can make covalent bond with thiol group. Therefore, CDr10b staining survives cell methanol fixing condition, while **CDr10a** signal is washed out. CDr10 stains cytosol of microglia cell, and the selectivity mechanism is not known. CDr10b stains activated microglia stronger than resting state microglia. The low toxicity of CDr10b allowed a movie of microglia attacking glioma cells

CDr10b cell staining was relatively resistant to washing with methanol and media whereas CDr10a staining was completely washed out.
