Injection into suspension cells
Direct intra-cellular delivery.
Researchers in immunology, hematology, CAR-T therapy projects, or in biologics production often have to work with non-adherent cells. These cells, like B- or T-cells, are known to be very difficult-to-transfect. In the new era of CRISPR gene editing, finding a tool that can efficiently, gently and easily deliver genetic material – or any kind of molecules – into suspension cells is particularly important for researchers in these fields.
FluidFM offers a unique approach to efficiently deliver by nano-injection any kind of soluble compound, directly into any adherent or suspension cells.

Injection into Jurkat cells
Jurkat cells (Human leukaemic T cell lymphoma) are a non-adherent cell line widely used in research as a model to study T-cell leukemia, T cell signaling or how T cells are infected by Human Immunodeficiency Virus. FluidFM offers a unique tool to researchers in these fields and others working with cells suspension to manipulate the genome or test drugs via nano-injection.

Inject, isolate and expand
As for adherent cell lines, FluidFM nano-injection into cells from a suspension culture preserves cellular viability. A single injected cell can be isolated with FluidFM pick & place into a separate well and expanded into a monoclonal culture.
