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, plaet）.

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.

Subc*tion Ratio: A subc*tion 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
