Fresh & frozen PBMCs – TEST

Fresh & frozen PBMCs

High-quality PBMCs delivered with consistency

We provide fresh and frozen PBMCs from a diverse pool of healthy, HLA-typed donors. Each sample is processed and cryopreserved under strict quality control to ensure high viability and reliable performance.

High-quality PBMCs for immunology, oncology and beyond

Rapid isolation for optimal viability

PBMCs are processed and cryopreserved within 5 hours of donation using Ficoll overlay and CryoStor CS10® with controlled-rate freezing to ensure exceptional viability and functionality.

Comprehensive donor selection

Choose from a large inventory of ready-to-ship frozen PBMCs or request fresh or frozen samples from custom donor collections matched by HLA type, age, sex, and more.

Flexible sourcing options

Access large numbers of vials from a single donor or build diverse panels from multiple donors, ideal for high-throughput, consistent experimentation.

Flexible formats available to meet your needs

Fresh PBMCs

Isolated from whole blood or leukapheresis samples using Ficoll density gradient centrifugation, fresh PBMCs are processed on-demand and shipped under controlled conditions.

Frozen PBMCs

Frozen within 5 hours of collection to preserve cell integrity, PBMCs are cryopreserved using CryoStor® CS10 and a controlled-rate freezing process. Ideal for flexible scheduling and long-term research without compromising recovery or performance.

What our customers say

“

"We have been using Research Donors as our supplier of frozen human PBMC cells for over a year. The cells are always delivered promptly and arrive on the date specified at the time of ordering. Further, the viability of the cells are higher than what we have observed from alternative suppliers and the numbers of viable cells always exceeds the specification. Communication is fast, friendly, and informative and the staff were very willing to adapt the product to our needs."

What are PBMCs?

Peripheral Blood Mononuclear Cells (PBMCs) are critical components of the immune system, comprising lymphocytes (T cells, B cells, NK cells) and monocytes. These cells play a crucial role in immunological research, vaccine development, and disease modelling.
