Product overview

Description & Application

PL-40​​ is a ​​cardiolipin-mimetic ionizable lipid​​ engineered for high-efficiency, antibody-free mRNA delivery to T cells. PL 40 LNPs exhibit a mean particle size of ​​120 nm​​, zeta potential of ​​-5.19 mV​​, and >80% mRNA encapsulation efficiency, with excellent plasma stability (≤5% size change after 6h in serum). Cryo-TEM reveals ​​polyhedral nanoparticles​​ with phase-separated domains, while SAXS confirms tight mRNA packing (d-spacing: ​​~3 nm​​ vs. 6.64 nm in conventional LNPs). AFM demonstrates exceptional rigidity (high bending modulus), enabling T cell-selective uptake via actin-mediated endocytosis (>2× higher than ALC0315 LNPs).In primary human T cells, PL40 LNPs achieve ​​>90% transfection​​ at 0.5 μg mRNA dose and sustain >100× higher luciferase expression than benchmark lipids. When delivering circular RNA, they extend protein expression ​​>5 days​​ with superior spleen tropism (spleen:liver ratio = ​​2.63​​). Crucially, they reprogram T cells into functional CAR-Ts in vivo without antibody conjugation, evading exhaustion markers (no Tim-3/PD-1 upregulation). Therapeutically, PL40-based uPAR-targeted CAR mRNA reduces liver fibrosis (​​collagen↓50%​​, ALT↓50%) and rheumatoid arthritis severity (​​clinical scores↓60%​​) by clearing senescent cells. Humanized anti-uPAR CARs delivered via PL40 show near-complete cytotoxicity (>95%) against uPAR+ cells, underscoring clinical translatability.

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.
