Overcome Cell Line Engineering Delivery Limitations with FluidFM

FluidFM CRISPR cell line development - Direct intra-nuclear injection of CRISPR complexes with FluidFM

For multiplex genome editing and fast cell line development.

The discovery of CRISPR-Cas9 for targeted gene engineering has revolutionized life sciences. Regardless of its broad introduction across many disciplines in biology, several challenges persist in editing cell lines, particularly for sensitive cells, or when multiple edits are required.

FluidFM offers a unique in-vitro gene editing supporting tool to improve the efficiency and applicability of CRISPR across a variety of cell types and for cell line development.

How FluidFM accelerates your CRISPR Cell Line Engineering

No need for carriers or vectors, no limitations by template size

As the CRISPR reagents are directly injected into the nucleus, there is no need to spend time and costs on designing complex plasmids. Also, when working with large repair templates or larger nucleases, there is no size limit as with viral carriers.

Especially suited for hard-to-transfect cells

The direct intra-nuclear injection with FluidFM is a very gentle and efficient transfection method. As the insertion of a FluidFM Probe does not compromise cell viability, it can even be used for injecting plasmids, gRNAs or CRISPR-complexes directly into the nucleus of many hard-to-transfect cells with exceptional viability, including stem cells, primary cells and neurons. 

Straight forward multiplexing & stack editing

The FluidFM Nanosyringe can be loaded with and deliver hundreds of different gRNA simultaneously and directly into the nucleus of a cell, for highly efficient multiplexing. However, if you prefer stack editing instead, the gentle injection procedure also enables consecutive editing of the same cell.

Maximizing HDR efficiency while minimizing off-target & side effects

Direct co-injection ensures that all CRISPR components are delivered simultaneously and at the right concentration into the nucleus. In addition, FluidFM enables quantification of the injected volume, allowing you to calculate exactly how many copies were delivered. This quantification is ideal for evaluation of dose/response relationships to effectively maximize HDR efficiency while minimizing off target effects. 

Monoclonal cell line development within 3 weeks

With the FluidFM single-cell approach, you already start from a single cell clone.  The FluidFM cell line development workflow, which combines gentle and accurate single cell isolation with the high efficiency of CRISPR gene editing, provides you with a stable, monoclonal cell line within 3 weeks, compared to 10-14 weeks with conventional approaches. Save your precious time, use FluidFM.

Save resources, time & money

CRISPR gene editing with the FluidFM workflow is done on a single cell level. The FluidFM nanosyringe is loaded with only 1µL, and only a dozen of cells is needed per experiment. As such, only a very low quantity of expensive reagents and precious cells are required to obtain your stable, monoclonal cell line by in less than three weeks starting from the day of transfection until the clones are characterized. Start with the needle, not the haystack.
