Each batch undergoes rigorous quality control for purity, concentration, and absence of contaminating nucleases or inhibitory substances.
2. Component Synthesis & Purification: Primers and probes are synthesized using phosphoramidite chemistry, followed by multiple purification steps (e.g., HPLC) to achieve >95% purity. Enzymes are produced through recombinant DNA technology and purified to an ultra-high standard, ensuring optimal activity and stability.
3. Buffer Preparation & Formulation: Proprietary reaction buffers are prepared under stringent aseptic conditions, incorporating stabilizers and enhancers to optimize PCR efficiency and shelf-life. Components are precisely measured and mixed to ensure optimal reaction kinetics for reverse transcription and PCR amplification.
4. Kit Assembly & Lyophilization: Master mix components (primers, probes, enzymes, dNTPs, buffer) are dispensed into reaction tubes or plates. For enhanced stability and ease of transport, many advanced kits utilize lyophilization (freeze-drying) to remove water, creating a dry, stable reagent pellet. This process mitigates the need for continuous deep-freeze storage for some components, improving service life and reducing cold chain requirements.
5. Quality Control & Testing (ISO/ANSI Standards):
