Ln-101

Gene Therapy for Muscle Recovery & Growth

Ln-1 plays a key role in muscle hypertrophy, repair, and vascularization. Our gene therapy delivers Ln-1 selectively to skeletal muscle via systemic administration, activating local growth without elevating systemic hormone levels.

Outcomes

Next-gen AI therapeutics development for achieving U.S. warfighter casulaty reduction and medical spin-outs

01

Next-Gen AI in Therapeutics Development

We deeply understand what it takes to stay at the forefront in the age of AI, using modular and scalable systems from target discovery up until the pre IND stage.

02

Governmental de-risking of high performance medicine

Governmental co-development

Armed with insights and experience in high-throughput robotics medicated research we collaborate with the US army to bring complex concepts to life, blending functionality with ease of use - serving our in-house feedback models.

03

Dual-use: Civilian & Casualty Reduction

Our technologies are uniquely positioned to deliver dual-use therapeutics for US warfighters, recruits and civilians.

04

Medical Spin-off Creation

The culmination of our bioinformatical and wet-lab efforts allow us to create novel technologies that have the potential for individual investment and growth.
