摘要:
长型肌球蛋白轻链激酶(long myosin light chain kinase,L-MLCK)及其分子内结构域的功能还不清楚.在研究其功能时,特异性抗体是一基本工具,但目前国际上还没有制备成功特异性较好的抗体.为此,我们先在大肠杆菌E.coliBL21中重组表达了鸡L-MLCK的4Ig蛋白片段(MLCK4Ig),蛋白经纯化后作为抗原免疫小鼠.在小鼠血清中检测到特异性抗体的基础上,建立了2株杂交瘤细胞株,获得抗鸡MLCK4Ig的单克隆抗体.该抗体可以特异与鸡L-MLCK和鸡MLCK4Ig反应.本文并对该抗体的特性及应用进行了讨论. 结果表明, 我们部分解决了L- MLCK的抗体缺乏问题, 为研究L- MLCK及MLCK4 Ig片段的功能提供了重要工具.
Abstract:
The functions of longm yosin light cha in k inase (MLCK) and the m ultip le dom a ins w ith in the m olecule were poorly understood. To our know ledge, there is no specific antibody aga inst L- MLCK so far, wh ich is essen tia l for the study o fL- MLCK. In this report, the 4 Ig fragm ent o f ch icken L- MLCK (MLCK4Ig ) w as expressed by using ofE. co li BL21 system, the pur ified prote in was used as antigen to induce antibody. Spec ific antibody was detected in the sera o f m ouse in jected w ith chickenMLCK4Ig. W e further estab lished two hybr idom a ce ll lines produc ingm onoc lonal an tibody, wh ich specifically reac ted w ith ch ickenMLCK4Ig o r ch icken L- MLCK. The character istic and usefulness o f the ant-i body we re a lso discussed. The resu lts show ed that ourwo rk partially so lved the prob lem o f L- MLCK antibody de fic iency, w hich prov ides an im portant too l fo r the functional investigation of L-M LCK andM LCK4Ig fragm ent
