Figure Lengend Snippet: Chrm3, Adra1a, Orai1, STIM1 protein expression in SMG and PG acinar cells. Western blot analysis was conducted to measure protein expression of Chrm3, Adra1a, Orai1 and STIM1 (A) in SMG and PG cells exposed to 0 (control), 100 and 150 μM H₂O₂. B-actin used as a reference protein. Orai1 and STIM1 protein expression in SMG and PG acinar cells were assessed by immunofluorescence microscopy, and their fluorescence intensities were measured in SMG (B, C) and PG (D, E) cells exposed to 0 (control), 100 and 150 μM H₂O₂. DAPI was used for nuclear staining. All photos were taken with the same exposure time (500 ms), analog gain (9.3x), and 40x magnification. Representative pictures from three independent experiments.
Article Snippet: Next, membranes were incubated overnight with unlabeled rabbit anti-Orai1 (Alomone Labs, Israel), mouse anti-Stim1 (Alomone Labs), rabbit anti-Chrm3 (Bioss, Massachusetts, United States), rabbit anti-alpha1a adrenergic receptor (Invitrogen, Thermo Fisher Scientific, Massachusetts, United States), mouse anti-beta actin (Proteintech, United States) at 4°C.
