Representative confocal microscopy images showing the co-localization of Compound 19 (CELT-483) with σ2 receptor expression in MCF7 cells. Cells were preincubated with 10 μM selective σ1 receptor agonist (+)-pentazocine for 2 h to mask residual σ1 receptor expression. This was followed by incubation for 1 h with the indicated fluorescent ligand at 5 μM. Then cells were fixed with paraformaldehyde, stained for σ2 receptor expression (TMEM97 ab) as well as nuclei (by DAPI), and analyzed by confocal microscopy. The ligand is colored red (scale bar of 20 μm).
Representative spinning disk images showing the localization of ligand Compound 19 (CELT-483) with the mitochondria as well as reduction of the Cy-5 signal in the presence of the nonfluorescent σ2 ligand DTG in living MCF7 cells. Cells were preincubated with 10 μM Compound 31 to mask residual σ1 receptor expression with or without 20 μM DTG for 75 min. This was followed by administration of 0.05 μM Compound 19 (CELT-483) for 30 min (red stain in the Cy-5 channel). In addition, mitochondria were stained with 250 nM MitoTracker-Bodipy FL (green stain in the GFP channel) and the nuclei were counterstained with Hoechst 33342 (blue stain in the DAPI channel). The depicted scale bar indicates 20 μm.

Our potent sigma hσ1/σ2 receptor fluorescent ligand is available in a 10 µg vial, allowing you to prepare 103 mL of 100 nM working solution to test σ1/σ2 receptors. Our CELT-483 product has been specifically designed to meet the needs of researchers in a variety of fields, enabling the study of σ1 and σ2 receptors with accuracy and precision. It has been validated in flow cytometry (Kd = 13.59 nM for σ2) and confocal microcopy in MCF7 cell lines (see publication for more details) to study both σ1 and σ2 receptors, using the appropriate masking agent.
