Arrayit Corporation Technology Speeds Allergy Testing

SUNNYVALE, CA--(Marketwire - August 27, 2009) - Arrayit Corporation (OTCBB: ARYC), a proprietary life sciences technology leader, announces the sale of instruments used to identify allergens in affected individuals.

For allergy testing, allergens are printed onto proprietary glass substrates to form microarrays. Serum samples from individuals with allergies are then reacted with the microarrays to allow binding between the allergens and molecules present in the patient’s blood stream. High-speed scanners read the microarrays to determine the nature of the allergic response in each individual. This same procedure can be used to decipher other immune and autoimmune conditions.
