🔬 1. Drug Concentration-Response Experiments

When studying the biological effects of drugs or chemicals, determining the concentration-response relationship is crucial. Here’s how you can use the 12-well plate:

• Serial Dilutions: Each well can represent a different concentration of the compound. Prepare your stock solution, then use serial dilution across the plate wells to achieve desired concentrations.
• Cell Response: Introduce your cells into each well, and observe their response to varying drug concentrations. This can help determine EC50, IC50, or cytotoxicity levels.

<p class="pro-note">🔎 Note: Accurate pipetting is crucial to ensure each well has the correct concentration, minimizing potential errors in data interpretation.</p>
