Unique high-through-put  extraction procedure for Neurotransmitters

This latest technology (sample clean-up device) provides a solution for the extraction of neurotransmitters/biomolecules from biological fluids wherein an ion exchange resin is attached to a solid support such as a multiwell plate (patent pending):

Advantages:

• Much more cost-effective than chromatography columns
• Fast and easy to use
• Suitable for biomolecules in different kinds of biological fluids
•  Improved sensitivity/small sample volumes
• Applicable in high throughput procedures  

GABA concentrations measured by a new ELISA in different regions of rat neuronal tissue:

Motor cortex	1137 ± 65
Somatosensory cortex	1379 ± 115
Hippocampus	1719 ± 219
Cervical sc region	484± 65
Thoracic sc region	395 ± 19
Lumbar I & II sc region	540 ± 80
Lumbar III – VI sc region	737 ± 32
Sacral sc region	687 ± 48

Histamine Research™ ELISA available now: multi-species ELISA for the quantitative determination of Histamine in different animal species and samples.

 

We announce with pleasure the introduction of new Fast Track assays for the determination of:

• Metanephrine in urine (RIA and ELISA)

• Normetanephrine in urine (RIA and ELISA)

• Combi kit Metanephrine/Normetanephrine in urine (RIA and ELISA)

• Serotonin (ELISA)

Are you still Using HPLC or LC/MS for the otherwise simple testing of Plasma Metanephrines?

LDN has long been a supplier of world leading assays for metanephrines both urinary and plasma. We have recently released our latest versions of these kits dubbed "Fast Track". They significantly speed up the time needed to run the assay all the while maintaining an excellent correlation to LC/MS.
