WEBINAR RECORDING: Radiolabelling and Plant Metabolism in Practice: From Design to Delivery

Webinar RECORDING

Originally Aired: October 15, 2025

Presenters: Oscar Ortiz-Escribano, Radiochemist, Labcorp; and
Robert Unsworth, Scientific Manager, Labcorp

Moderator: Solito Sumulong- Regulatory Affairs, SOLASTA Bio

Recap: Did you miss our deep dive with experts Robert and Oscar? This webinar uncovers the meticulous science and regulatory strategy required for successful C14 radiolabeled plant metabolism studies.

In this essential session, we broke down the complex technical hurdles that determine project success, including:

• The Regulatory Trigger: We explained the critical Total Radioactive Residue threshold and how it dictates the entire analytical path—from sample homogenization to exhaustive extraction.
• Synthesis Logistics: Learn how chemists manage complex syntheses that can take up to seven months. We also covered the processes required to maintain regulatory purity.
• Rotational Crop Strategy: Get the full picture on designing rotational studies, including the mandatory analysis of soil samples before sowing and after harvesting across various Plant Back Intervals (PBI).

Whether you’re new to agrochemical studies or a seasoned regulatory manager, this recording is packed with indispensable data and compliance insights.
