Bay Biosciences is a global leader in providing researchers with high quality, clinical grade, fully characterized human tissue samples, bio-specimens and human bio-fluid collections.
Samples available are cancer (tumor) tissue, cancer serum, cancer plasma cancer PBMC and human tissue samples from most other therapeutic areas and diseases.
Bay Biosciences maintains and manages its own bio-repository, human tissue bank (biobank) consisting of thousands of diseased samples (specimens) and from normal healthy donors available in all formats and types.
Our biobank procures and stores fully consented, deidentified and institutional review boards (IRB) approved human tissue samples and matched controls.
All our human tissue collections, human specimens and human bio-fluids are provided with detailed samples associated patient’s clinical data.
This critical patient’s clinical data includes information relating to their past and current disease, treatment history, lifestyle choices, biomarkers and genetic information.
Patient’s data is extremely valuable for researchers and is used to help identify new effective treatments (drug discovery & development) in oncology, other therapeutic areas and diseases.
This clinical information is critical to demonstrate their impact, monitor the safety of medicines, testing & diagnostics, and generate new knowledge about the causes of disease and illness.
Bay Biosciences banks wide variety of human tissue samples and biological samples including cryogenically preserved at – 80°C.
Including fresh frozen tissue samples, tumor tissue samples, FFPE’s, tissue slides, with matching human bio-fluids, whole blood and blood derived products such as serum, plasma and PBMC’s.
Bay Biosciences is a global leader in collecting and providing human tissue samples according to the researchers specified requirements and customized, tailor-made collection protocols.
