Human granulocytes (G) contain a vitamin B12-binding protein (B12BP). There is evidence that chronic myelogenous leukemia leukocytes (CMLL) may synthesize B12BP. Our prior studies suggested that intact, living intravascular G synthesize and release such protein into extracellular compartments in vivo.
