“I have used the GelCount for over 6 months.  The machine reduces the analysis time considerably when compared to manual counting, and the results are similar between them. It has also the added bonus of reducing the subjectivity that could arise by manual counting, making the clonogenics more reliable.  In addition, Oxford Optronix provides very good technical support.  Overall, I would recommend this product as it reduces the time and increases the confidence in your results.”

Over 200 peer-reviewed citations. Worldwide ‘gold standard’ in cancer biology colony/spheroid counting.

The Colony Forming Assay and colony counting is universally recognized as the gold standard method for measuring the effects of radiation, chemotherapeutic drugs and other agents on cell viability.

However, manually counting the resulting cell colonies is a thankless and laborious task in which consistent objectivity is difficult to achieve. 

GelCount™ is an easy-to-use, PC software-operated colony counter that automates the detection, counting and analysis of mammalian cell colonies in multi-well plates, Petri dishes and T25 flasks. Colonies can be adherent (typically stained), or non-adherent and unstained (free-floating or in semi-solid 3D matrices such as soft agar or methylcellulose). 

GelCount thereby provides a powerful and cost-effective alternative to the subjective and labour-intensive task of manual colony counting in the gold standard colony forming cell assay, also referred to as the clonogenic assay, the cell survival assay or the tumor cloning assay.
