BIOMOLECULE DELIVERY SYSTEMS / 伏悶蛍徨秘室g


The delivery of biomolecules in cells currently depend greatly on conventional methods such as electroporation, conjugation and transduction. However, although highly applicable, these methods can be tedious and time consuming. Low transformation efficiency and their applicability to certain bacterial strains is also known as a limitation. In our group, we try to employ cell-penetrating peptides as a tool to overcome some of these highlighted challenges.

SUMMARY: To further promote the efficicency of cell-penetrating peptide (CPP) permeation in diverse bacterial species, the critical side chain effects of CPP was evaluated. As a result, the introduction of shorter side chains to CPP sequences elevated CPP permeation in bacteria.

SUMMARY: To evaluate the applicability of cell-penetrating peptides (CPPs) as a biomolecule carrier with diverse bacterial strains, we evaluated and optimized factors that may play an important role in elevating CPP permeation efficiency. Based on our evaluation, we showed that 2 abiotic factors, temperature and tonicity promoted CPP permeation. Using our optimized conditions, we showed that CPP permeation was promoted in 9 out of 10 Enterobacteriaceae strains.
