Arrayit Technology Speeds Allergy Testing

SUNNYVALE, CA, Aug 27 (MARKET WIRE) --
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.
