Generation of multiple KO clones. One instrument, < 3 weeks. Monoclonality guaranteed. 


Find out how FluidFM can generate multiple KO clones in < 3 weeks in three simple steps:

Day 1: Injection of multiple gRNAs & Cas9
Multiple gRNAs are simultaneously delivered with the Cas9 into CHO cells. A fluorescent marker is co-injected to verify successful delivery.

  • Hands-on time: 30 minutes - from the loading of the FluidFM Nanosyringe until the injection of 50 cells is completed

Day 2: Isolation of the clone candidate
Selected cells are isolated into separate wells. Visual proof of single cell deposition ensures monoclonality.

  • Hands-on time: 30 minutes - for the preparation of the FluidFM Micropipette and the isolation of 12 injected cells expressing the fluorescent marker

  • More on FluidFM cell isolation

As of day 3: Clone expansion and analysis
Of the isolated clones, 90% developed into monoclonal colonies and 50% thereof showed mutations in targeted loci.

  • Strong reduction in complexity and development time of genetically modified cell lines starting from few nano-injected cells

Successful transfection of primary neurons with plasmids

With our system, even primary neurons can be transfected successfully and highly efficiently. The FluidFM nanosyringe directly delivers the complexes into primary neurons - gently and autonomously.

Conventional delivery methods applied to neurons are often inefficient, expensive and toxic to the neuron.

Transient expression of target proteins with mRNA

Human Dermal Fibroblast injected with GFP mRNA. 70% of injected cells expressed GFP 24h after injection.

Transient mRNA transfection helps to give fundamental insights on protein functions at a single cell level, such as protein expression and intercellular communication.

mRNA transfection using FluidFM nano-injection results in:

  • Higher transfection efficiency

  • Lower cell toxicity

  • Faster expression
