The Next Generation of Antibody Therapeutics

GigaGen is a pre-clinical biotherapeutics company based in the San Francisco Bay Area. Our team is comprised of innovative professionals with a proven track record of converting ground-breaking science into life-changing medicine.


Our science captures the genetic make-up of the entire human immune repertoire, characterizing B cells at a rate of millions per hour, while simultaneously identifying the antigens and proteins they bind to. It is our mission to discover and develop novel monoclonal and polyclonal antibody therapies that improve outcomes for patients with severe disease.


Biotherapeutics derived from immune repertoires have been selected for affinity and stability in vivo, increasing therapeutic potential. GigaGen has discovered therapeutic antibodies from immunized mice against important immuno-oncology targets and is in preclinical development for human repertoire derived polyclonals.
