CAR-T Cells Specificity Screening

Chimeric antigen receptor (CAR) T cell therapy shows long-term prospects for patients with the advanced disease by modifying the patient's own immune cells to recognize and attack specific tumors. Since treatment works by using the immune system, off-target activity promotes inappropriate immune responses and is very dangerous to patients.

Therefore, Creative Biolabs has developed Surfarray™ cell microarray technology for labeling and screening whole CAR-T cells, which is widely used to evaluate final engineered cells as well as precursor antibodies / scFv.

Specificity Screening for CAR-T Cells:

Creative Biolabs has two methods for targeted screening of CAR-T cells:

  • Screening antigen recognition elements - scFv
  • Screening of engineered CAR-T cells

Note: Early specific screening helps to select the right scFv to maximize the chances of producing the most promising potential CAR-T therapy. A more relevant assessment of off-target responsibility can then be provided by screening the entire engineered T cell (or final scFv). Since there may be inconsistencies between the original antibody / scFv and the final engineered T cells, both can be screened to ensure that the binding is not altered during development.

Key Features of CAR-T Cells Specificity Screening

High Specificity

Surfarray™'s low false positive rate ensures that months or years of research are not wasted to chase dead ends when verifying potential target hits. CAR-T cells specificity screening using Surfarray™ cell microarray technology typically reports one or two confirmed interactions, rather than 100 erroneous results often seen by protein microarrays. This saves months of verification and avoids unnecessary groping, which can affect regulatory submissions.

Creative Biolabs is dedicated to helping our worldwide customers shorten the discovery and development time in CAR-T cell therapy. We utilize unrivaled, proprietary drug design, study data, product candidate, advanced project life-cycle management, as well as real-time data to ensure the ideal outcomes.
