Optim Family – Protein Stability & Characterisation

Optim: A high throughput protein stability and characterisation platform

Optim is a family of innovative analytical instrument designed to probe multiple protein stability-indicating parameters at high speed using ultra-low sample volumes of proteins and other molecules.

Optims are compact robust, use a light scattering and fluorescence technology in a configuration never seen before and controlled by an all-new easy-to-use intuitive software package. The Optim platform has been designed to reduce the time and cost of therapeutic protein pre-formulation studies, protein stability testing, formulation development, and characterisation and comparability studies.

Optim will simultaneously measure a range of protein stability indicating parameters including unfolding transition temperature (Tm), aggregation onset temperature (Tagg) and rates of aggregation, giving you greater insight into identifying the candidate molecules or formulations with the most favourable properties much earlier in the development process. Earlier analysis eliminates the cost associated with the unnecessary development of candidates or formulations that do not have the potential to proceed and dramatically reduces the chance of late-stage failure.

Optim is designed to address three specific industry challenges:

  • The need for increased speed of analysis.
  • Low sample availability- especially in early development.
  • The desire to measure more stability indicating parameter.

Optim meets these challenges with its innovative features:

  • Speed of analysis: Capability to analyse up to 48 temperature controlled samples simultaneously. 144 samples measured in a high resolution thermal ramp per day
  • Low sample availability: Best in class sample volumes, only 9 microlitres per sample
  • Orthogonal stability indicating measurements: Simultaneous fluorescence and light scattering analysis for label free probing of both protein unfolding and aggregation. Analysis of the effects of temperature, time and chemical environment on your biomolecule


Optim is designed to measure the aggregation, unfolding and stability of microlitre volumes of candidate biopharmaceutical products under different physical, chemical and formulation conditions. Optim can be applied to:

  • Lead candidate selection and optimisation
  • Preformulation studies
  • Candidate formulation
  • Stability studies
