  Certificate of Analysis
Monoclonal Antibody: 1A6
Vial: Red Cap; 100µl
Immunogen: Mite (D. pteronyssinus) extract
Isotype: Mouse IgG1
Specificity: Binds to specific epitope present on D. pteronyssinus tropomyosin allergen, Der p 10. Cross reactive with shellfish tropomyosin.
Purification: Produced in ascites and purified by chromatography using Protein A. Single heavy and light chain bands on SDS-PAGE.
Concentration: 1.0mg/ml in phosphate buffered saline, pH 7.4.  Based on A280 for IgG (1.42=1mg/ml), 0.22μm filtered, preservative free.

  Certificate of Analysis
Polyclonal Antibody: Rabbit anti Shrimp Tropomyosin
Vial: Brown Cap; 100µl
Immunogen: Purified natural Shrimp Tropomyosin
Specificity: The pAb contains IgG antibodies to shellfish tropomyosin.
Composition: The pAb is in phosphate buffered saline, pH 7.4, containing 1% BSA/50% glycerol.  The pAb has been 0.22µm filtered and should be diluted 1/1000 for use in the Tropomyosin ELISA.

  Certificate of Analysis
Allergen Standard: Natural Shrimp Tropomyosin
Vial: White Cap; 400µl
Composition: Purified natural Shrimp Tropomyosin prepared in 1% BSA/50% glycerol/PBS, pH 7.4.
Concentration: 500ng/ml

The concentration of the purified natural shrimp tropomyosin was determined by amino acid analysis. There are no national or international reference standards for tropomyosin.

Specificity: The ELISA detects predominantly invertebrate tropomyosin from: dust mites (D. pteronyssinus and D farinae), cockroach, shrimp, crab, lobster, clam, and oyster. Mammalian or avian tropomyosin from beef, pork, lamb and turkey do not react in the assay.
