Notes:
Product Resources:EL-AF1 Certificate of Analysis

For research and commercial use in vitro: not for human in vivo or therapeutic use.


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.



Certificate of Analysis

Allergen Standard:rAsp f 1

Vial:White Cap; 400μl

Composition:Recombinant Asp f 1 prepared in 1% BSA/50% glycerol/PBS, 0.22μm filtered, preservative free, pH 7.4

Concentration:400ng/ml rAsp f 1

Concentration:  

The Asp f 1 concentration was determined by amino acid analysis.  Asp f 1 and Asp r 1 (mitogillin) are 95% homologous (differing by 4 amino acid residues) and are antigenically and functionally indistinguishable (1).
