Objective To identify gene mutation of a epidermolysis bullosa pruriginosa family. Methods Polymerase chain reaction, DNA squencing, multiplex PCR using allele-specific oligonucleotide primers.

采用聚合酶链反应，DNA直接测序以及等位基因特异引物的多重PCR方法，对一个痒疹样大疱性表皮松解症家系40人（其中患者23例）进行基因突变情况检测。

Methods The LPL cDNA was isolated from the human epiploon adipose tissue by means of RT-PCR. The LPL cDNA was ligated into the pcDNA3.1Zeo. The recombinant pcDNA3.1Zeo-LPL cDNA was identified by endonucleases, PCR and DNA sequencing. COS-1 cells were transfected with the recombinant LPL gene plasmid using Lipofectamine 20001M The LPL mass in cells and the culture medium were determined by a Markit-M LPL Kit. Spectrophotometry was used to measure the LPL activity.

采用RT-PCR法从人大网膜脂肪组织获取LPL cDNA基因，以pcDNA3.1Zeo质粒作为载体，运用基因克隆技术构建野生型人LPL cDNA重组质粒，限制性内切酶酶切、PCR以及双向测序鉴定重组质粒；运用Lipofectamine 2000将重组pcDNA3.1 Zeo-LPL cDNA质粒导入COS-1细胞，RT-PCR法检测LPL mRNA，ELISA法和比色法分别检测细胞裂解液及细胞培养基中LPL浓度及活性。
