Frequently Asked Questions
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.
