Human pediatric whole blood is a minimally processed peripheral blood specimen containing erythrocytes, leukocytes, platelets, plasma proteins, metabolites, and circulating soluble mediators. Pediatric blood is particularly relevant to research because the composition and phenotype of circulating immune-cell populations undergo substantial age-dependent changes from infancy through adolescence.

Key Features

• Age-Dependent Immune Profiles : T-cell, B-cell, NK-cell, and other leukocyte populations vary substantially with age, supporting age-stratified studies of immune development and maturation.

• Preserved Cellular and Soluble Components : Whole blood retains circulating blood-cell populations together with soluble plasma components for ex vivo cellular, molecular, and functional analyses.

• Low-Volume Applications : Whole-blood flow-cytometry approaches are suitable for pediatric research where available blood volume may be limited.

Research Use

• Flow Cytometry and Immune-Cell Phenotyping.

• Pediatric Immunology and Immune Maturation Studies.

• Hematology and Circulating Blood-Cell Research.

• Infectious Disease and Inflammation Research.

• Whole-Blood RNA Sequencing and Transcriptomic Profiling.

• Biomarker and Systems-Biology Studies.

• Age-Dependent Immune-Response and Vaccine-Response Research.
