项目摘要
We have developed a system to simplify the study of human cell surface
structures by procedures which permit study of antigens due to individual
chromosomes. A human-Chinese hameter, somatic cell hybrid, which contains
chromosome 11 as its only human chromosome has been produced. This hybrid,
which expresses human cell surface antigens, has been employed as a model
system to study these components using a combined immunological,
biochemical, and genetic approach. We have developed a deletion clone
panel of chromosome 11, which has enabled us to conduct a variety of
regional mapping studies including development of a new method using a
low-repeat human DNA sequence. The production of monoclonal antibodies has
allowed us to further characterize these antigens and to identify new
antigens encoded by chromosome 11. We have begun experiments which should
enable us to clone the genes for two of these antigens.
We have recently carried out similar studies using hybrids that retain only
human chromosomes 3 and 21. Deletion panels are being developed for these
chromosomes and have been used for regional mapping. Studies of this kind
should make possible rapid and definitive identification of a large variety
of human cell surface antigens which may influence malignant behavior of
human cells. The chromosomal location and biochemical identity of such
genetic determinants may help elucidate genetic relationships of antigens
involved in malignant response. (CS)

表达人类细胞表面抗原的细胞,
系统来研究这些成分,
生物化学和遗传学的方法。 我们开发了一个删除克隆
11号染色体的面板,这使我们能够进行各种各样的
区域绘图研究,包括开发一种新方法,
低重复人类DNA序列 单克隆抗体的生产
使我们能够进一步表征这些抗原,
由11号染色体编码的抗原。 我们已经开始了实验,
使我们能够克隆其中两种抗原的基因。
我们最近进行了类似的研究,使用的是只保留
人类3号和21号染色体 正在为此开发删除面板
