Karyotype of ATCC® HTB-55™
My lab uses Calu-3, an adenocarcinoma cell line derived from a pleural effusion, that we obtained from ATCC® HTB-55 ™. The cytogenetics data online suggests that normal chromosome 17 is "absent." However, we find the gene encoding NHERF-1, which is situated on chromosome 17, to be strongly expressed in this line. Is the karyotype provided by ATCC for HTB-55 incorrect?
