Western blot of HIF1α immunoprecipitated, using Aves Lab's PrecipHen® (cat. P-1010), from brain lysates of fish exposed for 6 h to normoxia (>7 mg O2 l−1; lanes 2, 5, 8, 10, and 11) or hypoxia (∼1 mg O2 l−1; lanes 3-4, 6-7, and 9). A positive HIF1α control is shown in lane 1 and the mobility of HIF1α and chicken IgY are shown by arrows (at left). HIF1α protein abundance in each sample was expressed as the ratio of the HIF1α band intensity to the IgY band intensity. Image CC-BY-4.0. PMID:38116983
Figure 1. Propidium iodide excitation and emission spectra.Figure 2. HL-60 cells were treated with a drug, then stained with FLICA® FAM-VAD-FMK poly-caspase inhibitor reagent (green) (Cat. 92) and propidium iodide (red) (PI). Scanning laser cytometer analysis. Four populations of cells were detected: (A) Unstained live cells, (B) red necrotic cells (PI), (C) green and red late apoptotic cells (FAM-FLICA® plus PI), and (D) green early apoptotic cells (FAM-FLICA®).
