Product Overview

Online Datasheet in PDF
Product Name
Ara h 2, Recombinant Protein
Full Product Name
Recombinant allergen Ara h 2 for Arachis hypogaea (peanut, groundnut)
Host
Pichia pastoris
Form/Format
Lyophilized
Concentration
2.32 mg/ml (lot specific)
Preparation and Storage
Protein is shipped with dry ice. Upon arrival, it should be aliquoted to avoid repeated freezing and thawing cycles and stored at -20ºC to -80ºC. In order to defrost the protein, maintain the aliquot at 25ºC without shaking to avoid aggregation.
Molecular Weight
determined by SDS-PAGE, the protein band is between the molecular markers of 35,000 and 25,000 Da, while relative molecular mass calculated from amino acid sequence and without glycosylation is 20,874.76 Da.
ISO Certification
Manufactured in an ISO 9001:2015 Certified Laboratory.
Application Notes for Ara h 2 recombinant protein
POSIBLE APPLICATIONS: WB, DB, Indirect ELISA, positive control in direct ELISA, CLIA, lateral-flow. Where this product has not been tested for use in a particular technique, this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates. Recombinant allergens expressed in E. coli do not contain glycosylation, and P. pastoris adds a different glycosylation than the one found in the environment and food allergens. As a result, allergens produced in these expression systems do not need anti-CCD blocker to eliminate the anti-CCD IgE antibodies present in normal human sera. In the specific case when you measure IgG with an allergen produced in P. pastoris, we recommend using our anti-CCD blocker to avoid cross-reaction with antibodies in sera which react with fungal high mannose glycans.
