History of Antibody Discovery
Since the 70s, scientists have progressively attempted to recreate
the human immune system’s most powerful disease fighting mechanism: first
through animal and chimeric hybridization and then humanized and recombinant
All of these methods had shortcomings through immune system rejection, toxicity, prohibitive costs, or limited antibody diversity.
Previous Limitations to Natural Human Antibody Discovery
1. Limited Lifespan of Antibody-Producing Cells Outside Body
2. Memory B Cell Rarity (0.001% of blood cells)
3. Signal among the noise - finding the most effective, relevant antibodies
Requires High Speed
Requires High Throughput
Requires High Resolution
How Our CellSpot Technology Works
The proprietary CellSpot discovery platform overcomes previous limitations to discovery
and identifies the most effective antibodies naturally expressed in healthy donors and turns
them into therapeutics.
Trellis monoclonal antibodies (mAbs) have demonstrated efficacy and safety in their original, healthy donors.
Trellis infectious disease mAbs have demonstrated greater potency (in vitro and in vivo) than those from competitors.
