Compatible with any species, and featuring detection limit of 0.1 µM and a dynamic range of 0.4 µM to 15.63 µM, this assay is also well-suited for the quantification of D-Serine in other matrices, including serum, cerebrospinal fluid (CSF), and cell culture supernatants.
- [Immuno-Oncology: A Practical Toolbox for Quantifying Amino Acid Metabolism](https://www.immusmol.com/immuno-oncology-a-practical-toolbox-for-quantifying-amino-acid-metabolism/): Cancer cells aggressively reprogram amino acid metabolism to sustain their rapid proliferation and survival. By doing so, they deplete the tumor microenvironment (TME) of essential nutrients—thereby suppressing immune cell function—and generate immunosuppressive metabolites. Over the past decade, Immusmol has developed ELISA kits and primary antibodies targeting key amino acids involved in cancer metabolism and immune modulation, to support research in immuno-oncology.

They serve as building blocks for neurotransmitter and protein synthesis, supply energy, detoxify ammonia, modulate synaptic function, and regulate gene expression. Measuring amino acids and their byproducts in blood, urine, or CSF is therefore critical for assessing neurodegenerative diseases, psychiatric disorders, brain tumors, traumatic injury, stroke, as well as rare neurological diseases.

With a minimal sample volume requirement of just 20 µL, our kits have been widely used to calculate the kynurenine/tryptophan ratio in various sample types, including cell culture supernatants, blood samples, and tissue homogenates from both animal and human origins. Here, we highlight key applications and research achievements made by our customers using our ELISA kits.

- [Imaging neurotransmitters, not enzymes, receptors, or transporters](https://www.immusmol.com/imaging-neurotransmitters-not-enzymes-receptors-or-transporters/): Dopamine, Serotonin, GABA, Glutamate, Histamine, Norepinephrine, Serine, Octopamine, ... To generate spatial information about key neuromodulators and neurotransmitters, neurobiologists typically perform stainings against enzymes (e.g. TH for dopamine, GAD65-67 for GABA), receptors (e.g. Glutamate) or transporters (e.g. Norepinephrine, Glutamate). Why?
- [Beyond TH: Imaging Dopamine Content in Midbrain Organoids for Parkinson’s Disease Modeling](https://www.immusmol.com/beyond-th-imaging-dopamine-content-in-midbrain-organoids-for-parkinsons-disease-modeling/): TH expression does not necessarily indicate that neurons are metabolically active and produce dopamine. Therefore, several groups interested in organoid-based modeling of Parkinson’s disease have combined standard markers of dopaminergic neurons, such as TH and GIRK2, with direct staining of dopamine using anti-hapten antibodies, as well as ELISA kits for quantifying dopamine release in supernatant.
- [Reveal serotonin in your samples using our dedicated tools](https://www.immusmol.com/reveal-serotonin-in-your-samples/): Serotonin (5HT) is one of the most potent monoamine neurotransmitters and peripheral signaling molecules. Therefore, tools allowing for the evaluation of serotonergic systems are valuable to approach the complex 5HT activities in physiological and pathological situations, but also to investigate mechanisms of action of novel disease-targeting therapies. For this purpose, we have set up and validated a series of experimental immunoassays specifically raised against 5HT.

As to investigate innovative direct or indirect modulators of IDO activity, Kynurenine and Tryptophan represent valuable biomarkers to be measured and can easily be adressed through ELISA kits which thus offer screening capacities.
- [Newly-released ELISA kit for Arginine (ARG)!](https://www.immusmol.com/107-news-newly-released-elisa-kit-for-arginine-arg-html/): Arginine (ARG) is a basic non-essential amino acid well known to participate in physiological functions such as i) vascular tone homeostasis as contributing to the production of nitric oxide (NO) and ii) immune response control, through NO synthase (NOS) and Arginase enzymes, respectively. Our new validated IS-I-0400 ELISA kit allows for the determination of ARG in serum and plasma samples of a volume as low as 20μL and with a sensitivity of 2.1µM.
- [Newly-released ELISA pack for Kynurenic / Quinolinic Acids](https://www.immusmol.com/106-news-newly-released-elisa-pack-for-kynurenic-quinolinic-acids-html/): Through the degradation of L-Tryptophan, the Kynurenine pathway (KP) generates a series of catabolites collectively known as Kynurenines, which can exert immunomodulatory and/or neuroactive properties. Known to respectively harbor neuroprotective and neurotoxic functions, Kynurenic (KYNA) and Quinolinic (QA) acids are found to be dysregulated in several neuroinflammatory disorders including Parkinson and Alzheimer disease but also Amyotrophic Lateral Sclerosis and Multiple Sclerosis. We developed novel ELISA detection kits to monitor the imbalance between KYNA and QA levels in neurological diseases and evaluate the ability of novel KMO inhibitors to restore equilibrium within the KP and mitigate neurodegeneration.
- [Homoarginine (hARG) ELISA kit out now!](https://www.immusmol.com/105-news-homoarginine-harg-elisa-kit-out-now-html/): HomoArginine (hArg) is a basic non-essential amino acid that exerts beneficial effects on vascular homeostasis, more likely through the increase of nitric oxide (NO) that can be explained through two mechanisms since hArg i) serves as a precursor of NO and ii) favors the elevation of L-Arg - main substrate of NO synthase - by inhibiting the enzyme Arginase. Our IS-I-0500 ELISA kit allows for the determination of hArg in serum and plasma samples in a minimal sample volume of 20μL and with a sensitivity of 125nM.
