Comments: The MEG-01 cell line was derived in 1983 at the Nagoya University School of Medicine, Nagoya, Japan from bone marrow cells taken from a patient in megakaryoblastic crisis of CML.
The cells are positive for cytoplasmic Factor VIII and surface GPIIb/IIIa, periodic acid - Schiff (PAS) reaction, alpha naphthyl acetate esterase and acid phosphatase.
They are negative for myeloperoxidase, alpha naphthyl butyrate esterase, naphthol AS-D chloroacetate esterase and alkaline phosphatase.
The stain positively with monoclonal antibodies BA-1 (anti B cell, granulocyte), HPL-3 (anti gpIIb/IIIa) and 20.3 (anti monocyte, platelet).
They are negative for other lymphoid and myeloid seris antigens.
Propagation: ATCC complete growth medium: The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Temperature: 37.0°C
Subculturing: Protocol: Subcultures are prepared by scraping the adherent cells into the medium. From the resulting suspension dilute cells to a concentration 1-2 X 10exp5 cells/ml into fresh medium in a new flasks. Keep culture below approximate density of 10exp6 cells/ml.
Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:3 is recommended
Medium Renewal: 2 to 3 times per week
Subcultures are prepared by scraping the adherent cells into the medium, and diluting the resulting suspension into fresh medium in new flasks.
Doubling Time: 36 to 48 hrs
Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2001
recommended serum:ATCC 30-2020
