758-可规模化DNA合成的制造感知生成模型

from 聊聊Sci

这项研究介绍了一种名为变分合成(variational synthesis)的创新方法,旨在解决生成模型设计生物序列时面临的制造瓶颈。传统的DNA合成方式因成本高昂而限制了设计规模,而该技术通过将机器学习算法直接映射到随机化学反应中,实现了超大规模的物理制造。研究人员成功合成了约10¹⁶个抗体设计样本,其序列的真实性与多样性可媲美最先进的人工智能语言模型。通过对这些合成序列进行功能筛选,团队发现了能够针对复杂细胞内靶点的治疗性嵌合抗原受体(CAR)候选药物。此外,该方法在Taq聚合酶及HLA肽组等多个领域的成功应用,充分证明了其在蛋白质工程中的通用性。这种制造感知型生成模型彻底改变了生物分子的发现效率,使大规模探索生命序列空间成为可能。References: Weinstein E N, Gollub M G, Slabodkin A, et al.
