Antibody Discovery

Single Plasma cell INterrogation®

High-throughput screening, integrated with our Antibody Discovery efforts, allows for the comprehensive analysis of the natural antibody repertoire. Our patented SPIN® platform employs microfluidic technology to isolate antigen-specific plasma cells, resulting in the delivery of antibodies with enhanced affinity and specificity.

Patented SPIN® Technology

High-throughput screening has enabled interrogation of the natural antibody repertoire. Our proprietary Single Plasma Cell Interrogation (SPIN®) platform uses microfluidic technology to isolate antigen-specific plasma cells and single-cell technology to analyze native paired antibody genes.

High affinity: High affinity antibodies are selected owing to the isolation of the terminal differentiated plasma cells

Broad spectrum of epitope coverage: Unique properties of the rabbit immune system allows to obtain antibodies against a broad spectrum of epitopes for a single antigen
