ASTM D6499 Antigenic Protein Testing in Hevea Natural Rubber
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.

Overview
Antigenic Protein testing in Hevea Natural Rubber as per ASTM D6499 is a specialized analytical method used to quantify proteins that can cause allergic reactions. Natural rubber derived from Hevea brasiliensis contains residual proteins, some of which are antigenic and may trigger latex allergies in sensitive individuals.
This test is essential for medical, healthcare, and consumer product industries to ensure the safety of latex-based products such as gloves, catheters, and elastic materials. By accurately measuring antigenic protein levels, ASTM D6499 helps manufacturers comply with safety regulations and minimize allergenic risks.
