  Certificate of Analysis
Monoclonal Antibody: 4A6
Vial: Red Cap; 100µl
Immunogen: Asp f 1
Isotype: Mouse IgG1
Specificity: Binds to a common epitope on Aspergillus fumigatus allergen, Asp f 1.
Purification: Produced in tissue culture and purified by chromatography using Protein G. Single heavy and light chain bands on SDS-PAGE.
Concentration: 2mg/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
Antibody: Polyclonal antibody raised against partially purified Asp f 1 (1,2).
Vial: Brown Cap; 100µl
Specificity: The pAb contains IgG antibodies to Asp f 1 as well as IgG antibodies to other Aspergillus allergens.
Activity: The pAb is in phosphate buffered saline containing 1%BSA 50%glycerol PBS, pH 7.4. The pAb has been 0.22µm filtered and should be diluted 1/1000 for use in Asp f 1 ELISA.
