Science & Technology

To measure or manipulate any biomolecule among a sea of non-target molecules requires exquisite molecular recognition

the issues with antibodies

Antibody-based products are the conventional solution for biomarker recognition. Antibodies, however, possess fundamental limitations that have created a bottleneck in market growth.

  • Limited Dx & Rx applications due to insufficient chemical modifiability and target range
  • Higher cost due to biological system, challenging quality control and refrigeration requirements
  • Slow development cycles due to prolonged antibody discovery (4-6 months)
  • Low performance due to fundamental limitations in affinity and specificity

the aptitude solution

Aptitude provides synthetic affinity molecules - a new generation of aptamers with major advantages.
