One-step purification of white blood cells WBCs is essential to automate blood sample preparation steps for WBC analysis but conventional methods such as red blood cell RBC lysis and density-gradient centrifugation typically require harsh chemical or physical treatment followed by repeated manual washing steps. Add 1 mL of RBC Lysis Bufferto every 500 µL of input blood volume 10.

A lymphocyte is small white blood cells usually 7 to 8 micrometers in length present in the blood.

White blood cells defend against infection and disease by ingesting foreign materials and cellular debris by destroying infectious agents and cancer cells or by producing antibodies. White blood cells circulate around the blood and help the immune system fight off infections.

Stem cells in the bone marrow are responsible for producing white blood cells. A high white blood cell count is called leukocytosis which is generally diagnosed when white blood cell levels exceed 11000mL.
