ASTM D6499-18 + Redline

1.1 This test method covers an immunological method to determine the amount of antigenic protein in Hevea Natural Rubber and its products using rabbit antisera specific for HNRL proteins. This immunoassay procedure quantitatively measures the level of antigenic latex proteins in solution using an inhibition format. The samples may include glove or other product extracts which have been collected in order to measure the HNR 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.
