Polcalcin Phl p 7, Calcium-binding pollen allergen Phl p 7, P7, Phl p 7.
Phl p 7.0101 is a secondary allergen of timothy grass pollen, which is non-glycosylated protein. Grass pollen-sensitized individuals show IgE antibodies in their blood system. Phl p 7.0101 is a calcium binding protein with similar sequence to pollen antigens that exist in different plants, hence, cross-reactions are possible.
Recombinant Polcalcin Phl p 7 produced in SF9 is a glycosylated, polypeptide chain having a calculated molecular mass of 8,805 Dalton.
Polcalcin Phl p 7 is purified by proprietary chromatographic techniques.
Polcalcin Phl p 7 is supplied in 20mM HEPES buffer pH-7.9 and 6M Urea.
Avoid multiple freeze-thaw cycles.
