The DAO ELISA kit is an enzyme immunoassay intended for the quantitative determination of diamine oxidase (DAO) in serum and dried blood spots.

DAO is a body‘s own enzyme that metabolises histamine.

Indications:

• Frequent headaches or migraine;

• Snuffles after consumption of histamine-containing nutrients;

• Tissue oedema;

• Eyelid turgor;

• Skin redness;

• Limb aches;

• Gastrointestinal discomfort;

• Monitoring of a histamine free diet.

The 25 (OH) Vitamin D dried blood ELISA kit s intended for the quantitative determination of the 25 (OH) Vitamin D in dried blood. 

Vitamin D regulates intestinal calcium resorption, bone mineralization, osteoblast differentiation, and bone matrix synthesis. 25 (OH) Vitamin D form is obtained after hydroxylation of Carbon 25 in the liver: this is the main form present in the circulating system, and its levels are use as an indicator for the general Vitamin D status of an individual.

Vitamin D deficiency has been associated to many diseases such as osteoporosis, rickets, osteomalacia, cancers and cardiovascular disease.

The IDO activity ELISA kit is designed to determine the determination of L-kinurenin and L-tryptophan in human serum, plasma and dried blood spots.

Indoleamine 2,3-dioxygenase catalyses the degradation of L-tryptophan (TRP) to L-kynurenine (KYN) and is the ratelimiting enzyme in this pathway.

IDO activity is an important regulator of the innate and adaptive immune system. It plays an important role in finetuning of the immune system, e. g. during the development and proliferation of cancer. 

The Nitrotyrosine ELISA kit is an enzyme immunoassay intended for the quantitative determination of protein-bound nitrotyrosine in human EDTA-plasma, serum and dried blood spots. 

The accumulation of protein bound nitrotyrosine is associated with cardiovascular diseases that are based on inflammatory processes (e. g., atherosclerosis, myocardial infarction, diabetic vasculopathy, hypertension, or coronary heart diseases).

A growing number of studies have also associated the accumulation of nitrotyrosine with neurological diseases (Alzheimer´s disease, Parkinson´s disease, multiple sclerosis, stroke). 

Nitrotyrosine is a stable product and might be seen as a correlate of peroxynitrite production, and its accumulation in cells and tissues is a marker of oxidative stress and nitrosative stress, respectively.

The CRP ELISA kit is a enzyme immunoassay intended for the quantitative determination of C-reactive protein in plasma, serum, stool, dried blood spots, and urine. 

Studies describe an association between inflammatory reactions and cardiovascular diseases like arteriosclerosis or latent and chronic persistent infections. As a marker for inflammation, CRP high-sensitive can be used to predict the risk of myocardial infarction and stroke. 

The CRP determination in urine allows – together with a2-macroglobulin – an early screening after kidney transplantations.

The Kynurenine ELISA kit is intended for the quantitative determination of L-kynurenine in human EDTA plasma, serum and dried blood spots.

L-kynurenine plays a key role as an immune suppressor in the course of infectious diseases (HIV, tuberculosis, borreliosis) and malignant diseases (colon cancer, lung cancer, leukemia, Hodgkin lymphoma, cervical cancer), where high kynurenine levels indicate a poor prognosis.

Thus, L-kynurenine serves as a prognostic marker to predict the progression and the severity of the disease.

The Tryptophan ELISA kit is intended for the quantitative determination of L-tryptophan in human EDTA plasma, serum and dried blood spots. 

Tryptophan is an essential amino acid which cannot be synthesized by humans, and therefore must be supplied in diet. It is the only source for synthesizing serotonin.

When tryptophan in plasma decreases, it is not available for serotonin synthesis and the following melatonin production. As a result, fluctuations of mood, aggression, sleep and eating disorder, or depression can occur.
