The en 455-3 modified lowry assay does not yield a reliable estimate of the allergenicity level of latex gloves with low total protein content.

Background: Estimation of the allergenicity of latex gloves by measurement of total extractable protein content with the modified Lowry method is not satisfactory. Therefore, complementary methods that are accurate, sensitive, and clinically relevant are needed. The Competitive Immunoassay for Antigenic Latex Proteins (CIALP) method described in a previous study could be a reliable complementary method for estimating the allergenicity of latex gloves.
