ASTM WK61243

    New Test Method for Immunological Assay to Quantify Extractable Guayule Natural Rubber (GNR) Proteins

    (What is a Work Item?)

    Developed by Subcommittee: D11.40 | Committee D11 | Contact Staff Manager


    1. Scope

    This test method covers an immunological method to determine the amount of extractable protein in natural rubber and its products using rabbit antisera specific for Guayule Natural Rubber latex (GNR) proteins. This immunoassay procedure quantitatively measures the level of GNR proteins in solution using an inhibition format. The samples may include but are restricted to, gloves or other GNR product extracts which have been collected in order to measure the protein levels. Although this method detects antigenic proteins, it should not be considered as a measure of allergenic proteins. Correlation of protein/antigen levels with the level of allergenic proteins has not been fully established.
