AVAILABLE TO ORDER
GRADE & PURITY BioReagent ? BioReagent grade — tested suitable for life-science and molecular-biology use. Use for cell culture, assays, and biochemical work needing biological compatibility. Biological Stain ? Biological stain grade — dyes characterized for staining cells and tissues. Use in histology and microscopy where staining consistency matters. for Fluorescence analysis ? Fluorescence-analysis grade — very low fluorescent impurities for clean spectra. Use in fluorescence assays where background interferes. for Microscopy ? Microscopy grade — reagents/stains suited to sample prep and imaging. Use in microscopy where clarity and low background are needed.

Overview

The styryl dye RH237 is a fast-response potential probe, primarily used for functional imaging of neurons, as well as for monitoring membrane potential, synaptic activity, and neuronal ion channel activity. Styryl dyes typically exhibit a blue shift of approximately 20 nm in their absorption or excitation spectra and a blue shift of 80 nm in their emission spectra.

Application

Membrane potential staining

Product Features

1. Stable performance: High fluorescence brightness and excellent photostability.

2. Low batch-to-batch variation: In-house developed product with stringent control over batch consistency.
