Africa can’t build outbreak readiness on fragile global supply chains.

When key lab reagents are imported, global delays and shortages quickly become local delays and higher costs, exactly when speed matters most.

Today at 15:00 CAT our CEO, Dr Genevieve Thompson, will be speaking on a Clinton Health Access Initiative - Africa CDC webinar on strengthening regional manufacturing and sustainable procurement for genomics and diagnostics.

We’ll also unpack Africa CDC’s continental listing approach: a structured way to review evidence, assess quality requirements, and independently verify performance, so countries can make faster, more confident procurement decisions during outbreaks.

I’ll share a high-level view of Gene Vantage and how regional manufacturing can help keep essential extraction reagents available and affordable.

🎤 Keynote: Dr Noah Fongwen (Africa CDC)
🎙 Moderator: Renuka Gadde (CHAI)

PCR Additives: Unlocking Tough Templates

Ever struggled with poor PCR results on GC-rich templates? You're not alone! 🧪
Try these proven additives:
- DMSO: Helps reduce secondary structures.
- Betaine: Perfect for reducing template complexity.
- Glycerol: Enhances enzyme activity.

Top Tip: Start small (e.g., 5% DMSO) and adjust gradually.

Mastering Gradient PCR

Gradient PCR is a powerful technique to optimize the annealing temperature for primers, a critical step for achieving specific and efficient amplification. By using a gradient thermal cycler, you can test multiple annealing temperatures in a single experiment, saving time and reagents while improving your PCR results.



Key Facts:
- Why it Matters: The annealing temperature directly affects primer binding specificity. Too low, and you risk non-specific binding; too high, and your primers might not bind at all.

- Optimal Tm Range: The ideal annealing temperature is typically 3–5°C below the primer’s melting temperature (Tm). For accurate results, always calculate Tm using online tools like NEB’s Tm Calculator.

- Gradient Setup: Set the temperature range based on your primer’s Tm. For example, if Tm = 60°C, a gradient range of 55–65°C is ideal. Use a mid-range gradient setting for initial trials, e.g., ±5°C.

- Interpretation of Results: After running the gradient, look for the lane with the brightest, most specific band on your gel. This corresponds to the best annealing temperature for your primers.

Bonus Tip: Gradient PCR is particularly helpful when troubleshooting primer-dimer formations or when amplifying templates with GC-rich regions.

Loading Dye Tips

Loading dye isn’t just a visual aid; it stabilises your sample and helps gauge how far the DNA has migrated during electrophoresis.

Key Facts:
1) Choose the Right Percentage: Use the following guidelines for loading dye based on your agarose gel percentage:
- 0.7% Gel: Best for fragments >1,000 bp.
- 1.0% Gel: Suitable for 500–1,000 bp fragments.
- 1.5% Gel: Ideal for 100–500 bp fragments.
- 2.0% Gel: Best for very small fragments

Perfecting PCR Primer Design

Primers are the foundation of successful PCR, as they determine both specificity and efficiency. Designing primers requires careful attention to sequence, length, and melting temperature (Tm).

Key Facts:
- Length: Primers should ideally be 18–25 bases long to ensure specific binding.
- GC Content: Aim for 40–60% GC content for stable binding.
- Avoid Secondary Structures: Avoid primer-dimers, hairpins, or repetitive sequences that reduce efficiency.
- Tm Matching: Primers should have Tm values within 2–3°C of each other to ensure simultaneous binding.
- Check Specificity: Use tools like NCBI Primer-BLAST to ensure primers don’t amplify non-target regions.

Bonus Tip: For tricky templates like GC-rich DNA, consider adding DMSO (up to 10%) to reduce secondary structures.

Tips for Running Long PCR

Amplifying long DNA fragments (>5 kb) poses unique challenges, but they can be tackled with careful adjustments.

Key Facts:
- Enzyme Choice: Use high-fidelity polymerases designed for long PCR (e.g., Q5 Long).
- Extension Time: Allow 60–90 seconds per kb at the extension step.
- Template Quality: Ensure template DNA is intact and free of nicks or contaminants.

Bonus Tip: Use DMSO or betaine to overcome secondary structures in GC-rich templates.
