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 (K_d = 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.
