Single Cell Cloning - Proof Of Monoclonality

Single cell cloning (SCC) represents a crucial step in cell line development. The aim of SCC is to identify wells where a single cell was seeded and to monitor its growth rate. To prove monoclonality for regulatory approval, it is essential to have a robust and reliable imaging system. CELLAVISTA 4 and NYONE automated cell imagers are well established in the field of cell line development. They combine robustness and reliability with a high image resolution (below 1 micron per pixel) to determine the clonality of a cell line.

Single Cell Cloning (SCC) using brightfield imaging

Our systems scan the whole wells of a microplate in bright field at high resolution after seeding the cells.


  • rapid cell cloning

  • no area in the well is missed

  • day-by-day automatable measurement

  • all colonies are recognized by our software

  • tracking back to the first day to demonstrate monoclonality

  • works with both adherent and suspension cells

  • automatic generation of a clone gallery

This provides a proof that your colony in fact grows from a single cell, or grows from a cell doublet.

FASCC (Fluorescence Activated Single Cell Cloning)

Ghost cells represent one of the main challenges in cell line development. Such undetected cells usually lie on the well edge. They are sometimes missed because most imaging systems for CLD are equipped with low resolution optics (2 microns per pixel), and only have a white light (brightfield) source.

This lack of resolution causes a lack of information within the image, and therefore it is hardly possible to distinguish cells from debris, or well edge artefacts. Because of this lack of precision, a correct statement about monoclonality is difficult.

Adding fluorescence enables the detection of these cells in a reliable way, even at the well edge! SYNENTEC has developed a unique method called FASCC to overcome all disadvantages of classic white light single cell cloning. FASCC provides a fully automated screening of your microplates by using the advantage of short term, non-toxic, and animal-free cell staining (e.g., CellTracker Green, Calcein AM). This unique tool presents a fast proof of monoclonality without guesses or doubts!


  1. a fast, low resolved (4x lens) high speed scanning mode (pre-scan) detect the fluorescence signal of e.g. Calcein-AM or Cell Tracker® stained cells

  2. the embedded image analysis tool excludes all wells seeded with more than just one cell or any number of cell-count the user sets up

  3. in the highly resolved Nanoview-scan all pre-scan results will be picked up and will be proceed by centering all single cells right in the middle of a single image (benefit: no cells on stitching boarder and fast scan despite high resolution)

  4. over expansion-period confluence measurement or suspension cell count with automated colony-detection can be performed to track cell proliferation

Please visit SYNENTEC’s website for more detailed information about CELLAVISTA 4 in virology and vaccine development.


The development of new drugs and biopharmaceuticals requires a precise experimental implementation. All steps to reach this goal involve time-consuming and labor-intensive laboratory testing. The automation of this process increases the throughput and quality of data, minimizes technician’s errors, and significantly increases the productivity of the lab.

SYNENTEC actively supports your daily laboratory work with their fully automated high-throughput cell imagers. Applications such as cell counting with viability, proliferation studies that help to determine drug sensitivity and resistance profiles, cell cycle and apoptosis monitoring, cell toxicity and DNA damage analyses, 3D cell culture assays, and surface marker analysis are only a fraction of the applications in which SYNENTEC’s versatile imagers provide an extremely valuable service to drug testing laboratories.

Preclinical Drug Testing

Cell migration assays are very important tools to study the invasion processes and metastasis of cancer cells. They are also used in arthritis and osteoporosis research. The simplest approach to monitoring a cell migration is the so-called “scratch” assay. A pipette tip is used to scratch or “wound” in a confluent cell monolayer. Then a microscope is used to observe cells filling in or “repairing” the wound.

SYNENTEC in collaboration with the team led by Prof. Susanne Sebens from the Institute for Experimental Cancer Research, CAU + UKSH Kiel, Germany, developed the fastest and most flexible automated wound healing application. This wound healing assay features a high-throughput analysis using the NYONE® Scientific automated cell imager and SYNENTEC's YT®-Software.

This wound healing method is described in this YouTube video.
