Macadamia Nut ELISA Kit

Full Name: Macadamia Nut ELISA Kit
Sample Type: Food (Sausage, Cereals, Cookies, Ice Cream, Chocolate) 
Sensitivity: 0.1 ppm


Macadamia nuts are members of the Proteaceae family of plants and has a natural whole food specifically contain vitamins, minerals and antioxidants that are able provide significant health-boosting potential. They are a native of the Australian bush. The high levels of magnesium it contains can help to prevent or regulate high blood pressure. Potassium helps regulate water intake and potassium can also provide elasticity to blood vessels, which may decrease the risk for developing heart disease and stroke. Manganese has been known as an important nutrient as it is a co-factor in several enzyme systems such as the reduction division system (i.e., catalase).

Another reason why it is beneficial is the fact that it contains amino acid l-arginine and this offers many vascular benefits to coronary heart disease patients. Some of the protein fractions in macadamia nut are known for being allergenic, these nut allergies are relatively seldom even though they can be very distinct in specific cases. However, the oil present is thought to be more allergenic and potent when it comes to allergic reactions. The oils present are not necessarily classified as being allergenic because they are mostly polyunsaturated fatty acids. which is not typically allergenic.


Macadamia nut ELISA kit can be used for analysing quantitative levels of macadamia nuts and their residues present in foods (for example cookies, chocolate, cereals, sausage and ice cream). This assay has a minimum analytical sensitivity limit of 0.1 ppm.


All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
