Abstract

Deletions spanning portions of the heavy chain constant region (CH) locus in murine plasmacytomas are revealed by hybridization with cloned immunoglobulin DNA molecules. The pattern of deletions suggests that a lymphocyte clone switches expression of CH genes by successive deletions and that the probable CH gene order is 5' mu-gamma 3-gamma 1-gamma 2b-gamma 2a-alpha 3'.

摘要

通过与克隆的免疫球蛋白DNA分子杂交,揭示了小鼠浆细胞瘤中重链恒定区(CH)基因座部分区域的缺失。缺失模式表明,淋巴细胞克隆通过连续缺失来切换CH基因的表达,并且可能的CH基因顺序是5' μ-γ3-γ1-γ2b-γ2a-α3'。
