Comparison between Poaceae pollen counts and ambient Phl p 5 concentration in Évora, south Portugal

Airborne pollen of grasses (Poaceae family) is the main aeroallergen in many european countries, namely in Portugal. Grasses includes many herbaceous species with an anemophyllous pollination

Grass Phl p5 aeroallergen quantification in outdoor air samples: correlation with pollen counts

Currently allergen exposure is estimated from pollen counts in air samples. However, there is not yet enough evidence to establish this technique as a reliable indicator of allergen exposure. Presently, there are a few reliable and sensitive ELISA methods that allow allergen quantification in environmental air samples but none is known to quantify Poaceae allergens. The aim of this work was to develop a novel approach to quantify Phl p5, one of the main allergen from Phleum pratense
