ALLERGENS VALIDATED IN OUR CHAMBER

MOUNTAIN CEDAR POLLEN

The Hill Country of Texas offers a unique opportunity for chamber testing utilizing this robust antigen. In the city of San Antonio, Mountain Cedar counts can exceed 50,000 grains/m3. It is estimated that 10-15% of the population living in Central Texas suffer from “Cedar Fever.”  Our database contains over 4,500 subjects with nasal and ocular symptoms due to Mountain Cedar pollen. Many pharmaceutical trials have successfully utilized the Mountain Cedar natural pollination season. Because of this unique situation, the first pollen validated in the Biogenics Research Chamber was Mountain Cedar. Our published data confirms the appropriateness of the chamber model utilizing this antigen.

RAGWEED POLLEN

Chamber studies have traditionally utilized ragweed pollen as the antigen. The Biogenics Research Chamber has performed validation studies utilizing ragweed pollen that, like Mountain Cedar pollen, elicited high nasal and ocular scores. Our database has more than 3,500 subjects with symptoms from this ubiquitous allergen.

OAK POLLEN

The Virginia Live Oak trees pollinate with vigor over a long spring season in Central Texas. With pollen counts that can rival Mountain Cedar in quantity, it is a very significant allergen in San Antonio. Validation studies in the chamber with this important spring allergen shows high nasal and ocular scores.

HOUSE DUST MITE ANTIGEN

Perennial Allergic Rhinitis (PAR) is a year-round problem that causes significant allergy symptoms.  The dominant cause of PAR on a world-wide basis is exposure to House Dust Mites.  The Biogenics Research Chamber has performed successful validation studies utilizing the House Dust Mite to produce significant nasal and ocular symptoms that are reproducible over an extended time period.

TIMOTHY GRASS

Grass pollen sensitivity is a major cause of allergic rhinoconjunctivitis throughout the world, affecting the majority of atopic individuals.   Biogenics Research Chamber is now validated to the Timothy Grass pollen.

 

There is ongoing validation of other pollens and aeroallergens.
