A Recent Cell Paper Reveals Bacterial “Nutrient Highways” in Insect Symbiosis — Powered by Invent Biotechnologies’ Total Protein Extraction Kit

In a 2025 Cell paper, Balmand and colleagues report the discovery of elaborate bacterial tubular networks that channel carbohydrates from endosymbiotic bacteria to their insect hosts, redefining how metabolic cooperation is achieved at the cellular level. By enabling efficient recovery of intact and representative protein fractions from symbiotic tissues, Invent Biotechnologies’ Total Protein Extraction Kit supported the detailed molecular and biochemical analyses underlying this work. The study highlights how advanced protein extraction technologies are essential for uncovering previously unseen mechanisms of host–microbe interaction and for translating complex cell biology into clear molecular insight.
