GABA and Glutamate

• Fully automated ‘in-needle’ OPA derivatization
• Post separation ‘wash’ to eliminate late eluters
• Small sample use of 5 µL
• Suitable for histamine and other LNAA’s

The ALEXYS Neurotransmitter Analyzer is a modular system that can be customized for the analysis of specific neurotransmitters. A sensitive method has been developed for the analysis of the amino acid neurotransmitters GABA and glutamate, as well as histamine and several other LNAA’s (large neutral amino acids). It has a fully automated OPA derivatisation procedure using an AS 110 user program. Late eluting peaks from the OPA reagent are conveniently removed by an automated wash step. GABA/Glu analyzer can be down-scaled to a sample volume < 10 µL.
