摘要

Chromosomes in human-mouse and human-(human-mouse)hybridomas wereanalysed by G-banding methods.It was found that most human chromosomes,exceptNo.13 and X,Y,were retained.The frequencies of chromosomes No.1,3,4,5,6,17,19,21 and 22 were higher than those of other chromosomes in each hybridoma clone.The myeloma cell lines X63-Ag8.653 and SHM-D33 were also analysed.The morphologyof marker chromosomes was apparently different between hybridomas.There were 7 kindsof marker chromosomes in human-mouse hybridomas and 16 kinds of markerchromosomes in human-(human-mouse)hybridomas.Clones that retained humanchromosome No.1 were more stable and clones that did not retain human chromosomeNo.14 were still capable of secreting human immunoglobulin.Clones that retained humanchromosome No.2 did not secret human k light chain McAb while clones that retainedhuman chromosomes No.2 and No.22 only secreted λ light chain.
