Two of these protein bands, with a molecular weight of 12 000 Mr and 14 000 Mr, showed immunoreactivity with IgE in the sera from patients with allergy to pollen of Caryota ochlandra. For the pollen extract of Carvota mitis, 30 protein bands were detected in SDS-PAGE, and three of these protein bands, with a molecular weight of 12000, 14000, and 26000 Mr, showed immunoreactivity with IgE in the sera from patients with pollen allergy of Carvota mitis. The 14000 Mr protein was the major allergen.
