• PubMed Abstract: 
  

  Grass pollen allergens are the most important and widespread elicitors of pollen allergy. One of the major plant allergens which millions of people worldwide are sensitized to is Phl p 2, a small protein from timothy grass pollen. Phl p 2 is representative of the large family of cross-reacting plant allergens classified as group 2/3. Recombinant Phl p 2 has been demonstrated by immunological cross-reactivity studies to be immunologically equivalent to the natural protein.
