Lenti-X T-Cell Transduction Sponge
The Lenti‑X T‑Cell Transduction Sponge is a novel technology that allows you to achieve microfluidics-driven lentiviral transduction efficiency gains in T cells without the use of microfluidics-based instrumentation. One sponge infused with an optimized blend of T-cell activation reagents (rhIL-2 and anti-human CD3 and CD28 antibodies) enables T‑cell activation and transduction in a single step of 105–107 cells without the need for time-consuming spinoculation or harsh, chemical transduction enhancers that require optimization to retain cell viability.

How does the Lenti‑X T‑Cell Transduction Sponge work?
A mixture of target cells (T cells or PBMCs) and lentivirus are added onto the sponge and incubated for 1 hr at 37°C to allow the mixture to be absorbed. Following absorption, cell culture media is added to the sponge, which is then incubated at 37°C for 48 hr.
After the incubation, you can easily release the transduced cells by infusing the sponge with a special release buffer. The sponge will dissolve during the subsequent wash steps, but this does not affect cell viability. These cells can then be plated for further expansion and downstream applications. The user-friendly protocol minimizes cell handling and requires smaller total reaction volumes, reducing the amount of virus needed. The Lenti‑X T‑Cell Transduction Sponge consistently delivers transduction efficiencies comparable to or superior to traditional methods.
Overview
- Conduct T‑cell activation and transduction in one step
- Achieve microfluidics-driven lentiviral transduction efficiency gains without the use of microfluidics-based instruments
- Skip labor-intensive, time-consuming spinoculation that requires additional centrifugation equipment
- Transduce 105–107 cells in the volume required for only one well of a 24‑well plate with each sponge
- End reliance on chemical-based enhancers (e.g., polybrene) that are toxic to certain cell types and require optimization to maintain cell viability during and after transduction.
