Identify the best potential drug candidates

The challenge

Characterising novel therapeutics during hit-to-lead, lead optimisation and candidate selection can be challenging:

  • A lack of access to the right equipment and assays impact the quality of your data
  • Training internal staff on specific assays requires time, money and resources and limits the number and range of assays you can effectively perform
  • The pressures imposed by ambitious milestones and finite budgets mean you sacrifice data depth and thereby lose important insights

The Arctoris approach to compound characterisation

Our end-to-end automated compound characterisation generates deeper and more robust data – in a fraction of the time normally required. This allows you to benefit from precise, reliable and reproducible results throughout the drug discovery process. By partnering with our team, you will be able to select the best possible drug candidates faster and with improved confidence.

The benefits of our end-to-end, automated cell-based and molecular-biology assays include:

Deep compound profiling and characterisation

Collect a rich dataset with all assays run to generate multidimensional data packages that measure every relevant parameter.

Our automated approach ensures every experiment is conducted the same way every single time, generating deep, reproducible data you can rely on.

Flexible access to a broad range of assays

Gain access to a wide range of assays, so you do not have need to invest in your own lab infrastructure - variable instead of fixed costs

By partnering with our senior team of experienced drug discovery experts, you will be able to select the best possible drug candidates faster and with absolute confidence.

Speed, accuracy and reproducibility

Generate data of unprecedented robustness and reproducibility via our fully automated process, eliminating human error & variability

Enjoy vastly reduced cycle times, helping you to scale your operations and make crucial go/no-go decisions as soon as possible.

Cell-based and molecular biology assays

We offer a broad range of cell-based assays to evaluate the effects of novel therapeutic agents such as small molecules, antibodies, antisense oligonucleotides, and peptides. Our platform enables target identification and validation, antibody and compound screening, and the generation of mechanistic insights. Our key molecular biology assays support you in elucidating patterns and changes in gene and protein expression. All assays are performed on quality-controlled cell lines with audited provenance and guaranteed authenticity and with highest quality research reagents.
