History
BioLegend was founded by CEO, Gene Lay, D.V.M., who was also the co-founder of PharMingen. In 2011, BioLegend co-developed and introduced Brilliant Violet(TM)-conjugated antibodies, using a novel fluorophore based on Nobel Prize-winning chemistry developed by Sirigen. In 2018, BioLegend introduced TotalSeq™ antibody-oligonucleotide conjugates for use in single cell proteogenomics analysis. BioLegend continued expansion and moved into a new 8 acre campus at BioLegend Way in 2019 with state of the art facilities designed to accommodate up to 1000 employees.
