Addgenies are excited to be at #AUTM this week, connecting with technology transfer professionals from around the world 🌍 Don’t miss the session, "Industry/Academia Connect & Collaborate – Part 1," where Addgene Co-founder & Chief Innovation Officer Melina Fan, PhD, will present.

The same priorities we’re focusing on at Addgene — efficiency and quality — are shaping biopharma R&D. A new #ScripAsks looks at what’s next, with Chonnettia Jones noting that 2026 will push doing more with less through CROs and AI-enabled workflows.

Collaboration drives scientific progress. In our latest blog, Chonnettia Jones reflects on how Addgene strengthened its foundations in 2025 and where we’re headed next to support the global research community. https://twp.ai/4iumZP

Planning to be in Seattle for the AUTM Annual Meeting on Feb. 8–11? Us too! Don’t miss the session, "Industry/Academia Connect & Collaborate – Part 1," where Addgene Co-founder & Chief Innovation Officer Melina Fan, PhD, will present. Stop by Room 606 on Feb. 9 at 1:45pm PT. https://twp.ai/4iuaQI

CRISPR is an RNA-guided gene editing tool. Except sometimes, a bit of DNA can help guide too! Substituting a few gRNA bases for DNA decreased off-target outcomes for several different CRISPR applications. Our new blog post on the topic has the details:
