Characterization of the Cell Type Targeted by AS1 Peptides

(A) The distribution of FITC-labeled, astrocyte-specific peptides (AS1; green) with MAP2 immunocytochemistry (red) in NSC-34 cells (neurons), with GFAP immunocytochemistry (red) in primary culture of astrocytes, and with Iba1 immunocytochemistry (red) in the primary culture of microglia after 24 hr of incubation with AS1 peptides (1 μg/mL). (B) The percentage of FITC-positive astrocytes binding to an astrocyte-specific peptide (AS1) in all GFAP-positive cells (red) (n = 6). Scale bars, 100 μm in (A). Error bar, mean + SD in (B).
