HUMAN Tissue Specimens

iSpecimen is your source for all types of human tissues samples from both healthy patients and those with medical conditions. Because we have access to the full electronic medical record, we can select and annotate specimens with molecular and genetic characterizations, treatment data, outcomes data, and other pertinent patient and specimen data.

Human tissue samples are also available to researchers in matched sets of tumor tissue, normal adjacent tissue and longitudinal collections from the same patient.

We also source biofluids and hematopoietic stem and immune cell products.

Tissue Samples To help Meet Your Precise Needs

The iSpecimen Marketplace™ is your one-stop source for all types of tissue samples, including matched sets of solid tissue, in a variety of formats.
