Product Name:
Pecan nut ELISA Kit
Description:
Pecan (also known as Carya illinoinensis) is a nut which comes from a tree that belongs to the walnut family (called Juglandiaceae). It is a species of the hickory native to Mexico and southern regions of United States. The amount of protein which is contained in a pecan nut is approx. 9% and some of these proteins are found to cause allergic reactions (for example the 11S legumin Car I 4 and the 2S albumin Car I 1).
The symptoms of pecan allergy vary considerably from one individual to another and this can also fluctuate from being mild to life-threatening in a single a single person based other specific factors and how much is consumed. Usually, the symptoms occur quickly within one hour of eating a pecan or a pecan-containing substance. The most common symptoms include: swelling, itching, vomiting, hives, wheezing, shortness of breath, coughing, nausea, dizziness, loss of consciousness and diarrhea.
One of the most effective way in preventing an allergic reaction is to avoid pecan exposure, this is quite difficult since very low levels of pecan nut can trigger an allergic reaction and in some severe cases lead to anaphylactic shock. Also, the existence of cross-contamination, is often noticed that is frequently due to a number of production process.
