Methods of applying proteins to surfaces to form arrays are well known. The immobilization may be covalent or noncovalent, via a linker moiety, or tethering to an immobilized moiety. These methods are well known in the field of solid phase synthesis and micro-arrays, for example as described in Beier et al., Nucleic Acids Res. 27:?1970-1-977? (1999), and U.S. Pat. No. 6,101,946 to Martinsky. Examples include binding moieties for attaching proteinaceous molecules to a solid support include streptavidin or avidin/biotin linkages, carbamate linkages, ester linkages, amide, thiolester, (N)-functionalized thiourea, functionalized maleimide, amino, disulfide, amide, hydrazone linkages, and among others. Furthermore, a number of companies offer commercial services for preparing protein arrays, for example Arrayit Corporation (Sunnyvale, Calif.). Preferably, the source of the proteins is an extract of the allergen source, such as those available from GREER® Allergy Immunotherapy (Lenoir, N.C.). Preferably, the extract of the allergen source is standardized.

Arrayit AllerSpot™ Companion Animal Testing Service using a 62-allergen microarray based on rigorous scientific studies and environmental research on various factors affecting the prevalence rates of allergies. Based on this information, we have identified a test for the most common allergens inhaled and ingested by our companion animal pets including dogs and cats. Ask your veterinarian about AllerSpot™.
Arrayit provides 7/2/18 FDA update: (1) excellent meeting, (2) large attendance by FDA top brass, (3) insightful and instructive, (4) our entire clinical team wishes to thank the agency for their feedback and generosity, and (5) we believe that our test will receive FDA approval.
Microarray tests for ovarian cancer, colon cancer and other cancers measure the activation of the immune system in response to tumor cell development. Pre-symptomatic and early stage cancer detection improves patient prognosis and healthcare treatment options.
