Sigma-Aldrich Product Name K562 Cell line human, 89121407, from human blood(chronic myelogenous

Human Caucasian chronic myelogenous leukaemia

Established from pleural effusion of 53 year old female with chronic myelogenous leukaemia in terminal blast crisis. Population highly undifferentiated and of the granulocytic series. Can be used as a highly sensitive target for the in vitro natural killer assay. Recent studies have shown the K562 blasts are multipotential, hematopoietic malignant cells that spontaneously differentiate into recognisable progenitors of the erythrocyte, granulocyte and monocytic series.

K562 cell line has been used to study the protecting role of cluster of differentiation-39 (CD39) attenuation against DNA damage. It has also been used to study the relevance of a novel sorting approach for separating cells, called “Slice and Dice Sorting”.[1][2]
