Cashew Nuts Antigen

Cashew nuts Antigen is a product used for allergen testing. It contains extracts or proteins derived from cashew nuts, which are a common allergen. This antigen is used to identify and diagnose allergic reactions to cashew nuts.
Cashew nuts Antigen is a specific substance used in the detection and measurement of allergens present in cashew nuts. Cashew nuts are a common allergen that can cause allergic reactions in susceptible individuals. The Cashew nuts Antigen is derived from proteins found in cashew nuts and is used in allergy testing to identify individuals who are allergic to cashew nuts. By measuring specific antibodies in the blood or conducting skin prick tests, healthcare professionals can accurately diagnose cashew nut allergies and provide appropriate management and treatment plans.

Background

Cashews contain a high level of proteins that are considered heterologous proteins to the human body. In individuals with compromised immune function, consumption of cashews may stimulate abnormal immune responses, leading to allergic reactions. Cashew-induced allergic reactions may include tachycardia, throat swelling causing airway obstruction, fainting, dizziness, and loss of consciousness. Even the ingestion or inhalation of trace amounts of cashew can result in anaphylactic shock.

Cashew is an important tree nut allergen and contains three major allergenic components: Ana o 1, Ana o 2, and Ana o 3. The major cashew allergens were recombinantly expressed in Escherichia coli, and the immunological activity of the recombinant proteins was identified using cashew-allergic sera. Using an indirect ELISA method, recombinant antigens were coated onto microtiter plates, reaction conditions were optimized, and cashew-allergic positive and negative sera were tested to establish a component-resolved diagnostic method for cashew allergy.
