Conglutin-7, 2S protein 1, Seed storage protein SSP1, Seed storage protein SSP2, Allergen Ara h 2.
Ara h 2 comprises of 2 isoforms: Ara h 2.0101 and Ara h 2.0201. Ara h 2.0201 is the most important peanut allergen which binds IgE. Ara h 2.0201 is a Weak inhibitor of trypsin and is a conglutin storage protein which accounts together with Ara h 6.0101 for the majority of the IgE immune response.
Recombinant Allergen Ara h 2.0201 produced in SF9 is a glycosylated, polypeptide chain having a calculated molecular mass of 19,365 Dalton.
Ara h 2.0201 is expressed with a 10xHis tag at N-terminus and purified by proprietary chromatographic techniques.
Ara h 2.0201 is supplied in 20mM HEPES buffer pH-7.6, 250mM NaCl and 20% glycerol.
Avoid multiple freeze-thaw cycles.
