Human whole blood is a complex biological matrix containing erythrocytes, leukocytes, platelets, plasma, and circulating molecular components. Because it retains circulating blood cells within their complex cellular and plasma milieu, whole blood is widely used in research investigating immune responses, hematological processes, inflammation, infectious diseases, and systemic biomarkers.
Key Features
-
Circulating Cellular Composition : Contains major leukocyte populations, including neutrophils, monocytes, lymphocytes, eosinophils, and basophils, together with erythrocytes and platelets.
-
Reduced Cell-Isolation Manipulation : Enables analysis of immune-cell phenotypes and functional responses without the additional isolation steps required for purified leukocyte preparations.
-
Versatile Research Matrix : Can be used for leukocyte isolation, immunophenotyping, molecular analyses, and ex vivo immune-cell stimulation assays.
-
Biomarker Research : Whole-blood gene-expression profiling can characterize systemic immune-associated transcriptional states and support biomarker discovery.
Usual Research Uses
-
Flow Cytometry and Immunophenotyping : Characterization and quantification of circulating leukocyte populations and immune-cell phenotypes.
-
Leukocyte Isolation: Serves as starting material for the isolation and downstream study of specific blood-cell populations.
-
Ex Vivo Immune-Cell Stimulation : Assessment of cellular responses to defined stimuli and investigation of immune activation pathways.
-
Inflammatory-Response Studies : Evaluation of cellular and molecular responses associated with inflammation.
-
Blood Transcriptomics : Analysis of whole-blood gene-expression profiles to investigate systemic immune-associated transcriptional states.
-
Infectious-Disease Research : Investigation of host cellular and molecular responses to infectious agents.
-
Circulating Biomarker Research : Analysis of cellular, protein, nucleic-acid, and other molecular biomarkers present in blood.
