Species: Sorghum halepense (Johnson grass)
NCBI Taxomony ID: 4560
Biochemical name:Beta-expansin
MW(SDS-PAGE):30-35 kDa
Allergenicity:Sor h 1 is recognized on immunoblots of Johnson grass extract by Mabs raised against Cyn d 1 and by IgE from pooled sera of individuals allergic to Bermuda grass. When tested with 64 grass pollen-allergic patients from a subtropical region, 49 showed IgE reactivity with purified Sor h 1 in ELISA. Of 49 patients with positive SPT to Johnson grass, 97% showed IgE reactivity with Sor h 1 in ELISA.
