abstract = "Aims and scopes: It is known that sub-pollen particles (SPP) cause more severe symptoms of asthma than its whole pollen grain counterparts,
due to its smaller size and ability to penetrate deeper into the lungs. To reveal other possible causes of such more severe asthma symptoms
induced by Ambrosia artemisiifolia SPP, its sub-pollen particle and pollen grain proteomes were characterized and compared.
Experimental description: Protein extract of short ragweed (Ambrosia artemisiifolia) pollen and its SPP were prepared and subjected to
denaturing 2-D electrophoresis. Pollen proteome spots were excised a er colloidal coomassie blue brillinat (cCBB) staining and in gel digested
for liquid chromatography coupled with high resolution LTQ Orbitrap XL hybrid mass spectrometry. Parallel to that, cCBB stained gels were
analyzed and quanti ed with laser scanner Typhoon 7000 series and Image 2D Master Platinum 7.0 soware (GE Healthcare, USA).
Results:
ere is statistically signi cant di erence between the contents of major allergen Amb a 1.05 subgroup in the ragweed whole
pollen grains and SPP, the latter being richer in Amb a 1.05 (2 times), in major allergen Amb a 11 (5 times), in minor allergens Amb a 4 (7
times) and Amb a 6 (4 times). e 30 kDa basic antigen group in SPP (8 times more abundant) needs further investigation.
sia artemisiifolia allergens, Amb a 1.05 and Amb a 11, minor allergens Amb a 4 and Amb a 6 which could contribute to more severe asthma
symptoms caused by SPP.",
