In-Vitro Setup to Test Hydroxy-Propyl-Methyl-Cellulose as Allergen Barrier over a Span of 360 Minutes

Powder hydroxy-propyl-methyl-cellulose (pHPMC), insufflated in the nose, swells and makes a gel barrier against offending allergens. Most clinical studies demonstrating efficacy of pHPMC have been done in patients sensitized to grass and birch pollens.We set up an in vitro study to document the reduction by pHPMC of the diffusion in agar of 3 other common allergens.
