Healthy Plasma

Healthy Human Plasma for Control and Baseline Research

Healthy Plasma is collected from IRB-consented, clinically screened healthy donors and processed within one day of collection to preserve key analytes such as cytokines, proteins, and metabolites. It supports research into inflammatory pathways, immune profiling, and biomarker discovery as matched control material. Anticoagulant type and aliquot volume are configured per project and reported per lot. Bulk plasma is available.

Why Plasma from Healthy Donors

Plasma is the fluid fraction of anticoagulated blood, separated by centrifugation without allowing the blood to clot. That distinction from serum is not cosmetic; it determines which analytes survive and which assays the specimen is fit for.

• Because coagulation is prevented, fibrinogen and the clotting factors remain intact, making plasma the required matrix for coagulation and fibrinolysis research.
• No clot forms, so platelets are not activated during processing and platelet-derived mediators are not released into the fluid — a major source of artefact when serum is used for cytokine and growth factor measurement.
• Plasma is the conventional matrix for circulating cell-free nucleic acid and extracellular vesicle research, where cellular lysis during clotting would contaminate the analyte of interest.
• Anticoagulant choice is part of the experimental design: EDTA chelates divalent cations and is standard for nucleic acid work, citrate is used for coagulation testing, and heparin is used where downstream enzymatic activity must be preserved. Specifying the tube up front avoids an unusable specimen.
• Healthy plasma defines the baseline against which a disease-state signal is measured; without an identically collected and processed control arm, apparent biomarker differences may reflect pre-analytical handling rather than biology.
• Because our healthy and disease-state collections run under the same protocols and processing windows, pre-analytical variables are held constant across the comparison.
