Introduction

The development and production of antigen-antibody tests are critical for diagnostic purposes, particularly in detecting infections and diseases. This article outlines the detailed process used in the production of antigen-antibody tests, presenting specific parameters and methodologies used in the industry.

Production Process of Antigen-Antibody Tests

Step 1: Antigen Preparation

The first step in producing an antigen-antibody test is the preparation of the antigen. Typically, the antigen is obtained through recombinant DNA technology or isolation from a pathogen. It must be purified to a concentration of at least 95% purity for optimal test performance.

Step 2: Antibody Generation

Polyclonal or monoclonal antibodies are generated using laboratory animals or cell cultures. Monoclonal antibodies are often preferred for their specificity. The antibodies are harvested and purified, achieving a concentration of approximately 1 mg/ml for use in tests.

Step 3: Conjugation and Immobilization

The purified antibodies are then conjugated with a detectable marker, such as an enzyme or a fluorescent dye, and immobilized onto a test strip or plate. The ratio of antibody to marker is meticulously controlled, typically around 1:1 or 1:2, to ensure proper functionality.

Step 4: Assay Validation

Validation of the test involves sensitivity and specificity analysis, with a target sensitivity of over 95% and specificity of 98%. Several samples with known antigen levels are tested to confirm the accuracy of the assay.
