Established from bone marrow cells of an 11-year-old girl with T cell acute lymphoblastic leukemia (T-ALL) in relapse; cell lines BE-13 and PEER show identical DNA fingerprints and hence share common origin, presumably due to cross-contamination; however, their diploid and tetraploid karyotypes indicative of earlier and later passage numbers, respectively, suggest that BE-13 is derived from PEER, rather than vice-versa; carries NUP214-ABL1 fusion gene
Human flat-moded hypotetraploid karyotype - 81-89<4n>XXXX, +1, +4, -9, -9, -10, -16, -21, del(1)(q13.2), add(1)(p11-21), del(4)(q11q31.2)/i(4p)x2, i(4q)del(4q31.2)/i(4q)add(4)(q31)x2, del(5)(q14q21)x2, del(6)(q22)x2, del(9)(p22)x2, der(17)t(17;?21)(p11;q1
single round cells growing in suspension
Mycoplasma: contamination was eliminated with Mycoplasma Removal Agent, then negative in DAPI, microbiological culture, RNA hybridization, PCR assays
Immunology: CD2 -, CD3 +, CD4 +, CD5 +, CD6 +, CD7 +, CD8 -, CD13 -, CD19 -, CD34 -, TCRalpha/beta -
Storage and Shipping
