Peripheral blood is collected by venepuncture by qualified clinicians. Samples are obtained using Research Ethics Committee (REC) approved consent forms and protocols. The entire process is fully customisable, from collection through to delivery. 

Pooling: Individual donor

Filtration: Not filtrated

Donor demographics: Age, Ethnicity, Sex. Further demographics/clinical information available upon request

Anticoagulant : Dipotassium ethylenediaminetetraacetic acid (K2-EDTA)

Product Format: Fresh peripheral blood collected in a vacutainer of choice. Maximum collection volume in one sitting is 75-100 mL

No BBV testing is conducted on fresh samples, therefore, this product should be treated as potentially infectious. Ensure proper personal protective equipment (PPE) and safety protocols are followed when handling this product.

• For short-term storage, maintain at 2–8 °C after collection unless otherwise specified by the assay requirements.
• Do not freeze whole blood.
• Process within 24 hours of collection for most downstream applications (e.g., PBMC isolation, plasma separation).
• Samples should remain in original anticoagulant tubes (e.g., EDTA, heparin) until processing.
• For PBM isolation, processing within 6-12 hours is recommended for optimal viability.

Note: Viability and cellular composition may be affected by transport duration and downstream handling conditions.

Suitable for a wide range of research applications involving circulating blood cells and plasma components. Common uses include PBMC isolation, immune monitoring, biomarker discovery, molecular analyses (DNA, RNA), plasma or serum preparation, assay development, and functional cellular studies. For research use only. Not intended for clinical or diagnostic procedures.

Fresh Biospecimens – General Considerations

Handling:

Fresh samples should be maintained at 2–8 °C and processed as soon as possible upon receipt.

Limitations:

Fresh biospecimens are sensitive to transport and handling conditions. Variations in processing time, temperature exposure, and downstream handling may affect cell viability, cellular composition, and molecular integrity.
