Quality > Quantity: Is your Lentivirus actually working? 🦠
In viral vector production, a high titer can be misleading. Are you counting "empty envelopes" or delivered messages? ✉️
This month, we’re breaking down:

🔹 Functional Titer: The true measure of infectious potency (the "hits"). 🎯
The Takeaway: A high Physical-to-Functional (P:F) ratio can cause cell toxicity without the results you need. Know your IU/mL for a precise MOI! 🧪✨
