Lucifer Yellow CH, Lithium Salt, 25 mg (Invitrogen™)

Lucifer yellow CH, lithium salt is a water-soluble dye with excitation/emission peaks of 428/536 nm. It is a favorite tool for studying neuronal morphology, because it contains a carbohydrazide (CH) group that allows it to be covalently linked to surrounding biomolecules during aldehyde fixation. The lithium salt form of the lucifer yellow CH is commonly used for microinjection because it has higher solubility than the potassium and ammonium salt forms of lucifer yellow CH.

To make a concentrated stock solution, dissolve in H₂O up to 8% (w/v). Store frozen and protected from light.
