What Is ASTM D6499 Insecticide Treated Material Knockdown?
ASTM D6499-24, Standard Test Method for Immunological Measurement of Antigenic Protein in Hevea Natural Rubber (HNR) and its Products, is published by ASTM Committee D11 on Rubber and Rubber-like Materials and developed by Subcommittee D11.40. It describes an immunoassay that uses rabbit antisera specific to Hevea natural rubber latex proteins to quantify antigenic latex protein in solution. The assay runs in an inhibition format. Protein extracted from the sample competes with latex antigen for a limited amount of antibody. More protein in the extract means less free antibody is available to bind the reference antigen, so the signal drops. Samples are usually extracts prepared from gloves or other rubber products. Results fall in the microgram to milligram range, and the method can also detect and quantify Hevea natural rubber protein contamination on test items.
Why does the standard exist? Common colorimetric protein assays can give misleading results in latex, where chemical additives interfere, and protein levels in many finished products fall below their detection limits. An antibody-based measurement responds specifically to latex proteins. The scope itself draws a line. The method detects antigenic proteins and shouldn’t be treated as a measure of allergenic proteins, because the correlation between the two hasn’t been fully established. Results describe how much latex antigen is present. They don’t predict how a particular person will react to a product.
The 2024 edition is the active revision. It follows D6499-18 (reapproved 2023) and a line of earlier editions that began in 2000. Full procedure details, including reagent preparation and acceptance criteria, sit in the paywalled standard. Infinita Lab therefore runs the work against the current edition and documents the extraction and assay conditions for every submitted sample.
Applications and Benefits of ASTM D6499 Insecticide Treated Material Knockdown Testing
Scope
This method detects and quantifies antigenic proteins in natural rubber products.
- The method covers an immunological procedure for measuring antigenic protein in Hevea natural rubber and its products.
- Rabbit antisera specific to Hevea natural rubber latex proteins supply the antibody.
- An inhibition-format immunoassay quantifies antigenic latex protein in solution.
- Because the measurement is made on protein brought into solution, samples may be extracts of gloves or other rubber products.
- Measurable quantities fall in the microgram to milligram range.
- Test items can be checked for the presence and amount of Hevea natural rubber protein contamination.
- Only antigenic proteins are detected. This is not a measure of allergenic proteins, because that correlation is not fully established.
- As an alternative to colorimetric protein assays, it avoids the spurious results those assays can give in the presence of latex additives.
- Responsibility sits with the user to set appropriate safety, health and environmental practices and to check regulatory limits before use.
- Development followed internationally recognized principles on standardization set out by the WTO Technical Barriers to Trade Committee.
Applications
- Measuring extractable antigenic protein in natural rubber latex examination and surgical gloves.
- Other dipped or molded latex articles, such as balloons, tubing, and catheter components, can be screened for residual latex antigen.
- Did extra leaching or chlorination actually lower protein levels in finished goods? The assay can answer that.
- Hevea latex protein contamination on equipment, packaging or supposedly latex-free items.
- Protein content compared between production lots or between suppliers of natural rubber compounds.
- Data for product files that support regulatory submissions and customer quality requirements.
Benefits
- Antibody-based detection responds to latex proteins specifically, so it’s less affected by additives that distort colorimetric assays.
- Low protein levels in an extract? The inhibition format suits that situation.
- Quantitative results allow lot-to-lot and supplier comparisons on the same footing.
- The same method also covers contamination checks on items that should be latex-free.
- Manufacturers and buyers get a shared reference for reporting protein data from a recognized, current ASTM method.
- Reporting the antigenic limitation clearly keeps readers from treating the result as an allergy prediction.
Our ASTM D6499 Testing Procedure
Sample Extraction
Antigenic proteins are extracted from the rubber sample using a suitable extraction solution under controlled conditions.
1Immunoassay Preparation
The extract is prepared and reacted with specific antibodies to target antigenic proteins.
2Detection Reaction
Binding between antibodies and proteins is measured using a calibrated detection system.
3Quantification and Analysis
Protein concentration is quantified based on calibration standards and reported as antigenic protein content.
4ASTM D6499 Test Parameters and Requirements
| Parameter | Details |
|---|---|
| Test principle | Immunological assay (ELISA-based methods) |
| Target analyte | Antigenic proteins in natural rubber |
| Extraction medium | Aqueous buffer solution |
| Detection method | Antibody-antigen binding |
| Measurement range | Low ppm to trace protein levels |
| Sensitivity | High sensitivity to allergenic proteins |
| Analysis time | Defined incubation and reaction periods |
- Microplate Reader – Reads the optical signal from each well so extracts can be compared against the standard curve.
- Microplate Washer – Clears unbound reagents between assay stages. Background stays low.
- Analytical Balance – Product portions and reagents are weighed accurately, which lets results be expressed per unit of sample.
- Orbital Shaker or Extraction Bath – Samples sit at controlled conditions here while extractable protein moves into the extraction fluid.
- Calibrated Pipettes and Dispensers – An inhibition curve depends on repeatable volumes of standards, extracts, and antiserum, and these deliver them.
- Temperature-Controlled Incubator – Keeps conditions steady during antibody and antigen binding steps.
- Data Analysis Software – Fits the standard curve, then calculates protein concentration for each extract.

- Standard curve used to quantify the samples, with the fit and any control results.
- Extraction conditions, sample portion, and extraction volume, described for each item.
- Which edition of the standard was applied, plus any deviations from the written method.
- One plain note: the result measures antigenic protein and is not a measure of allergenic protein.
ASTM D6499 Insecticide Treated Material Knockdown FAQs
The test quantifies allergenic proteins responsible for immune responses. By identifying and controlling protein levels, manufacturers can reduce sensitization risks, ensuring safer latex products for users in medical and consumer applications.
Total protein includes all proteins, but only specific antigenic proteins trigger allergic reactions. Measuring antigenic proteins provides a more accurate assessment of allergy risk and helps in developing safer low-protein latex products.
If protein extraction is incomplete, the measured antigenic protein levels will be underestimated. Efficient extraction is critical for accurate quantification, as it directly influences the reliability of the immunoassay results.
Factors include processing conditions, washing efficiency, vulcanization, and storage. Inadequate processing can leave residual proteins, increasing allergenic potential and affecting test results.
It enables developers to optimize formulations and processing methods to minimize allergenic proteins, improving product safety and acceptance.
