Applications: transfection host (Nucleofection technology from Lonza) Tumorigenic: Yes Reverse Transcript: negative Antigen Expression: CD7 (25%) DNA Profile (STR): Amelogenin: X CSF1PO: 9,10 D13S317: 8 D16S539: 11,12 D5S818: 11,12 D7S820: 9,11 THO1: 9.3 TPOX: 8,9 vWA: 16 Cytogenetic Analysis: The stemline chromosome number is triploid with the 2S component occurring at 4.2%. Fifteen markers (M1 and M(15)) occurred in nearly all S metaphases. Spontaneous non-specific dicentrics occurred, but rarely. Unstable markers were also rarely seen. The X was disomic, and N9 was nullisomic. Isoenzymes: AK-1, 1 ES-D, 1 G6PD, B GLO-I, 2 Me-2, 0 PGM1, 0 PGM3, 1 Age: 53 years Gender: female Comments: The continuous cell line K-562 was established by Lozzio and Lozzio from the pleural effusion of a 53-year-old female with chronic myelogenous leukemia in terminal blast crises. [22609] The cell population has been characterized as highly undifferentiated and of the granulocytic series. [26059] Studies conducted by Anderson, et al., on the surface membrane properties led to the conclusion that the K-562 was a human erythroleukemia line. [26060] The K-562 cell line has attained widespread use as a highly sensitive in vitro target for the natural killer assay. [48829] [1101] [48830] See Pross, et al. for a detailed analysis of the in vitro assay of NK cells including the mathematics of quantitation of NK cell activity. [48833] K-562 blasts are multipotential, hematopoietic malignant cells that spontaneously differentiate into recognizable progenitors of the erythrocytic, granulocytic and monocytic series. [26061] The effect of inducers on sublines derived from the original K-562 cell line have been reviewed by Koeffler and Golde. [867] Cultures from the ATCC stock have been shown to exhibit this sensitivity for assessing human natural killer activity. Karyological studies on various K-562 sublines have been classified into three groups (A,B,C) by Dimery, et al. [26063] The strain obtained by the ATCC most closely resembles the B population. Occurrence of the Philadelphia chromosome, however, was of much lower frequency; none detected in 15 metaphases examined. The line is EBNA negative. Propagation: ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Iscove's Modified Dulbecco's Medium, Catalog No. 30-2005. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%. Atmosphere: air, 95%; carbon dioxide (CO2), 5% Temperature: 37.0°C Subculturing: Protocol: Cultures can be maintained by the addition or replacement of fresh medium. Start new cultures at 1 X 10 exp5 viable cells/ml. Subculture at 1 X 10 exp6 cells/ml. Medium Renewal: Every 2 to 3 days Preservation: Freeze medium: Complete growth medium 95%; DMSO, 5% Storage temperature: liquid nitrogen vapor temperature Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2005 recommended serum:ATCC 30-2020 purified DNA:ATCC CCL-243D purified RNA:ATCC CCL-243R References: 867: Koeffler HP, Golde DW.
