Laboratory animal allergy: the measurement of airborne urinary allergens and the effects of different environmental conditions

Lab Anim. 1983 Jul;17(3):235-9. doi: 10.1258/002367783781070696.

Abstract

Casella Simquad air samplers, with 0.5 microM cut-off filters, were employed to sample the air in a laboratory animal house environment. The extracts obtained were assayed for laboratory animal urinary protein allergens using the inhibition radioallergosorbent test (RAST inhibition). The results showed that the collection and assay methods were of value and studies were extended to the influence of air change rates and humidity on airborne allergen levels. Reducing the air changes increased allergen levels, whilst increasing the humidity from 54% to 77% caused a significant reduction in allergen levels.
