Cells are untouched and ready for downstream applications. PB was collected using acid-citrate-dextrose solution A (ACDA) as the anticoagulant. B cells, also known as B lymphocytes, are a type of white blood cell of the lymphocyte subtype. They function in the humoral immunity component of the adaptive immune system. B cells produce antibody molecules which may be either secreted or inserted into the plasma membrane where they serve as a part of B-cell receptors.
