Like listening to the musical instruments in a symphony, scientists use multiomic technologies to investigate how layers of molecular components behave in a single biological sample, revealing more direct connections behind complex cellular processes.Image credit:istock, imaginimaSimilar to the many musical instruments that make up a symphony, biological systems comprise multiple layers of molecules and pathways that intersect and interact to orchestrate cohesive cellular processes. Capturing how each unique component relates to one another can be challenging for researchers working on discoveries that requires multiomic methods often necessitating assumptions based on data collected from separate samples.The five dimensional multiomics system AVITI24 from…
