Overview of PBMCs

Peripheral Blood Mononuclear Cells (PBMCs) are key to our immune system. They help fight off infections and diseases. These cells are vital for studying the immune system and for medical research.

Defining Peripheral Blood Mononuclear Cells

PBMCs are a type of white blood cell with a single, round nucleus. Lymphocyte separation shows they make up about 60% of white blood cells in healthy adults. The main types are:

  • T cells (60% of PBMCs)
  • Monocytes/macrophages (15%)
  • Natural killer cells (15%)
  • B cells (10%)

Role of PBMCs in Immunology

These cells are vital for our immune system. They move through our blood to find and fight threats. Mononuclear cell isolation helps scientists learn how they protect us.

PBMC Type Percentage Estimated Cells per mL
T Helper Cells 70% of T Cells 210-840 cells
Cytotoxic T Cells 30% of T Cells 90-360 cells
B Cells 10% 50-200 cells

Importance of PBMC Isolation

Getting PBMCs is key for research, like finding new medicines and vaccines. A good PBMC sample has over 90% of cells alive. This makes it very useful for science.

PBMCs give us a peek into how our immune system works. They help scientists find new ways to prevent and treat diseases.

Step-by-Step Process of Leukopak PBMC Isolation

Getting peripheral blood mononuclear cells (PBMCs) from leukopaks needs careful steps. Researchers must follow a detailed plan to get high-quality cells for scientific studies.
