使用尺寸切割的 cDNA 文库作为探针和竞争剂的竞争杂交策略被设计用于克隆其 mRNA 受转录调节或丰度随细胞系或细胞周期变化的基因。我们使用这种策略从着色性干皮病 (XP) 互补组 A 家族的三个成员的 mRNA 的特定大小部分构建 cDNA 文库。来自父亲、母亲和孩子的成纤维细胞系的尺寸切割的 cDNA 文库用于竞争方案中筛选两个 λgt11 人类 cDNA 文库。在已表征的 15 个阳性 λgt11 克隆中,至少 14 个克隆代表相同的基因,相对于纯合子受影响的孩子,该基因在母亲和父亲 XP 专性杂合子中以更高的丰度存在。
A competition hybridization strategy using size-cut cDNA libraries as both probe and competitor was designed for the cloning of genes whose mRNAs are either regulated transcriptionally or vary in abundance as a function of cell line or cell cycle. We used this strategy to construct cDNA libraries from a particular size fraction of mRNA from three members of a xeroderma pigmentosum (XP), complementation group A family. Size-cut cDNA libraries derived from the father's, mother's, and child's fibroblast cell line were used in a competition scheme to screen two λgt11 human cDNA libraries. Of the 15 positive λgt11 clones which have been characterized, at least 14 clones represent the same gene which is present in greater abundance in both the mother and father XP obligate heterozygotes relative to the homozygous affected child.
