Latex allergies - standardization of the allergen quantification in products and air samples obtained from the workplaces and the prevention of the hypersensitivity reaction due to latex

Project No. BGFA ALL007


completed 12/2001


Aim of this project was the development of standardized methods to determine the most important latex allergens in diagnostics, products of latex and in dust samples of work places.


Determination of latex specific IgE; cloning and expression of recombinant allergens as fusionproteins with maltosebinding protein or with histidin-tag, purification of recombinant proteins due to affinity chromatography. Enrichment of monoclonal antibodies by in vitro production in a modular minifermenter and affinity purification, optimizing of two sided immunoassays for quantification of Hev b 1 and Hev b 6.01, inhibition test to quantify total latex allergen content, quantification of Hev b 5 by using inhibition assay with Hev b 5-specific IgE containing patients sera.


Nine clones of latex allergens are available at the BGFA: rHev b 1, rHev b 2, rHev b 3, rHev b 5, rHev b 6.01, rHev b 6.02, rHev b 6.03, rHev b 8, rHev b 10. Methods for determination of three of them (Hev b 1, Hev b 6.01 and Hev b 5) are available so far. More than 80% of tested latex sera of health care workers reacted to rHev b 5. In collaboration with industry latex-specific IgE-tests (CAP) were improved by addition of rHev b 5.

Description, key words:

Allergies to latex proteins affect the skin as well as lower and upper airways. As most important allergens the allergens Hev b 1, Hev 6.01 and Hev b 5 were investigated. Measurement methods using monoclonal and polyclonal antibodies or inhibition methods using patients IgE were developed.
