Medchemexpress LLC Lucifer yellow CH dilithium salt | 67769-47-5 | MFCD00006922 | 98.4% | 457.25 g/mol | C13H9Li2N5O9S2 | 5 MG

Lucifer Yellow CH dilithium salt is a water-soluble, high-intensity fluorescent tracer containing a hydrazide functional group. It is used for intracellular injection, neuronal morphology visualization, gap junction coupling studies, and other applications that require a polar, membrane-impermeant fluorescent probe.

High fluorescence intensity for sensitive detection.
Water-soluble formulation for easy dissolution in aqueous buffers.
Excitation ~428-430 nm and emission ~536-540 nm for common fluorescence setups.
Hydrazide group enables reaction with aldehydes for covalent labeling.
Solid, yellow to orange appearance suitable for handling and storage.
High purity (HPLC) for reproducible experimental performance.
