Deliver your CRISPR-Cas complexes directly to where they are needed: the nucleus

Designed for pharmacologists and molecular biologists, the FluidFM CRISPR is the most reliable and cell-friendly solution to edit the genome of adherent cells.

Unlike traditional transfection methods, benefit from requiring only a small number of starting cells thanks to high-viability and transfection efficiency even on notably hard-to-transfect cell types. 

With the CRISPR system, pass easily over the cytoplasmic and nuclear membranes in directly delivering the material to the nucleus, making sure that your CRISPR-Cas complexes and repair template reach their targets. This increases the chance of HDR events to happen.

With the integrated Volume Calculator feature, calculate precisely the number of delivered complexes and optimize the dosage to maximize on target and minimize off target effects.

Perform multiplex editing – deliver as many gRNA as you want in a single nucleus, in a single injection.

Product Highlights
  • Selective, direct & gentle intra-cellular injection
    Precisely select single cells based on their phenotype and deliver with the tiny FluidFM nanosyringe (aperture 600 nm) CRISPR-Cas complexes exactly where you need them – the nucleus. The cell’s membrane instantaneously reseals when the nanosyringe is retracted, resulting in cell viability of over 95%.
  • Intuitive & easy
    Benefit from simple preparation and extensive automation and data management combined with our user-friendly and intuitive software. Simply point and click on the cytoplasm or nucleus of the cells you want to target and click "OK". It is as straightforward as that.
  • Volume calculator
    Calculate precisely the number of delivered complexes with the integrated Volume Calculator feature. This is particularly useful when you want to optimize the dosage to maximize on target and minimize off target effects.

  • Proven injection protocols
    Access Cytosurge's database of proven injection protocols, see here.
  • Observe & follow up
    Cytosurge's software records the XY-coordinates of the edited cells and allows the user long-term observation of the modified cells with the desired settings (fluorescence filter, exposure time etc...). Observe any point of interest and follow how events unfold with multi-channel time-lapses.
  • Save on material costs
    Only 1µl of CRISPR-Cas solution is required to inject thousands of cells.


According to the high definition image of the cells on the screen, chose the cells of interest according to their phenotype. Select hundreds of cells under visual control, selectively target for the nucleus or cytoplasm.

Easy walkthrough procedures

  • Follow the in-software suggested instructions to optimally deliver your CRISPR-Cas complexes into the nucleus

  • Apply recommended injection settings from our protocols database

  • Easily tailor injection parameters to your cells by changing few parameters (injection pressure, injection time, exerted force and approach speed)

  • Finally, step back and let the CRISPR system autonomously deliver the CRISPR-Cas complexes
