Product overview

Description & Application

TS41 is a trisulfide-derived ionizable lipid engineered for lipid nanoparticles (LNPs) to deliver mRNA therapeutics against multidrug-resistant bacterial pneumonia. Its optimized formulation, TS41S LNP, combines TS41 with helper lipids (e.g., DOPE, cholesterol) at a precise ratio, achieving a hydrodynamic diameter of ~105 nm, low polydispersity, and high mRNA encapsulation efficiency (~84%). This design enables efficient pulmonary delivery via intratracheal administration, with luminescence signals in lungs 4.8-fold higher than clinical benchmarks like SM-102 LNPs, ensuring targeted expression in epithelial cells, macrophages, and neutrophils. Crucially, TS41 LNPs exhibit potent anti-inflammatory properties by scavenging reactive oxygen species (ROS), reducing neutrophil infiltration and proinflammatory cytokines (e.g., IL-6, TNF-α) in infected lungs. In preclinical models, TS41S LNP encoding PB9 peptibody mRNA eradicated pathogens like Staphylococcus aureus and Pseudomonas aeruginosa, improved survival rates to 80%, and minimized tissue damage without systemic toxicity. Its ROS-scavenging capability synergizes with antibacterial effects, offering a promising, translatable platform for combating resistant infections while controlling inflammation. Future enhancements, such as codon optimization or inhalation delivery, could further broaden its therapeutic potential.

Handling guidance

Shipping, storage and sampling

How is the lipid shipped, and how should I store it?
We generally ship the neat (undissolved) lipid compound rather than an ethanol solution. The neat lipid is stable during transport with ice packs, and shipments originate from Shanghai. Pure form: store at −20 °C for up to 1 year. In solvent: store at −80 °C for up to 6 months or at −20 °C for up to 1 month. Keep sealed and protected from light. Avoid repeated thaw cycles for best results.
Pure lipid or solution — which should I choose?
Pure lipid is generally more stable during shipping and storage, so we usually recommend the pure form. A solution in ethanol or chloroform can be supplied when required by your workflow. Tell us the intended application, solvent and target concentration so the most suitable format can be confirmed.
How should I measure a small amount of oily or viscous lipid?
Ionizable lipids are often oily liquids or viscous semisolids, so material can be lost during repeated weighing or transfer. For a small pack, dissolve the entire quantity and aliquot it volumetrically. For example, add 1 mL ethanol to 25 mg lipid to prepare a 25 mg/mL stock, then use a pipette to withdraw the required amount. For quantities above 100 mg, direct weighing with an analytical balance may be more practical. Always confirm solvent compatibility and solubility first.
Can you support formulation optimization and scale-up?
Yes. Share the RNA cargo, target tissue, administration route, formulation method and assay plan. Our team can discuss starting molar ratios, N/P ratio and scale-up requirements for research workflows.
