    • The present invention relates to a stable, pseudotyped retrovirus packaging cell line comprising packaging cells which generate helper-free recombinant pseudotyped retrovirus. The packaging cell line comprises one or more non-retroviral expression constructs, such as an expression construct with the human cytomegalovirus (CMV) immediate early promoter or derivatives of this promoter (e.g., pMD), which direct expression of: (a) retroviral gagpol genes and (b) a non-retroviral gene which is under the control of an inducible operator system and whose gene product pseudotypes retroviral core virions. The present invention further relates to a method of making a stable, pseudotyped retrovirus packaging cell line which generates helper-free recombinant pseudotyped retrovirus. The present invention further relates to the particular packaging cell lines described herein (i.e., H29 gagpol, H29 new gagpol) and the particular cells and constructs (i.e., packaging elements) used to produce the stable, pseudotyped retrovirus packaging cell line described herein (e.g., H29 cells and pMD, pMDtet, pMDtet.G, PMD.gagpol, pMD.new gagpol constructs). The present invention relates to a retroviral vector for producing a cDNA library for expression in mammalian cells, comprising two retroviral long terminal repeats, a cloning site for insertion of cDNA and a cytomegalovirus promoter. The invention also relates to a cDNA library for expression in mammalian cells, the library comprising retroviral vectors of the present invention. The present invention also relates to a method of expression cloning in mammalian cells. The present invention also relates to a method of cDNA expression cloning in mammalian cells. The present invention also relates to a method of identifying a gene defect responsible for a mutant phenotype using cDNA expression cloning by complementation in mammalian cells.

    • Mycobacterium tuberculosis genes encoding five immunologically relevant proteins have been isolated by systematically screening a lambda gt11 recombinant DNA expression library with a collection of murine monoclonal antibodies directed against protein antigens of this pathogen. One of the M. tuberculosis antigens, a 65kD protein, has been shown to have determinants common to M. tuberculosis and M. leprae. In addition, genes encoding proteins of other mycobacteria (M. africanum, M. smegmatis, M. bovis BCG and M. avium) have been isolated. Isolation and characterization of genes encoding major protein antigens of M. tuberculosis make it possible to develop reagents useful in the diagnosis, prevention and treatment of tuberculosis. They can be used, for example, in the development of skin tests, serodiagnostic tests and vaccines specific for tuberculosis.
    • 已经通过用针对该病原体的蛋白质抗原的鼠单克隆抗体的集合系统地筛选λgt11重组DNA表达文库来分离编码五种免疫相关蛋白的结核分枝杆菌基因。 结核分枝杆菌抗原(一种65kD蛋白)中的一种已被证明具有与结核分枝杆菌和麻疯病菌相似的决定因素。 此外,已经分离了编码其他分枝杆菌蛋白质的基因(M. africanum,M.耻垢分枝杆菌,牛分枝杆菌BCG和鸟分枝杆菌)。 编码结核分枝杆菌主要蛋白质抗原的基因的分离和表征使得开发可用于诊断,预防和治疗结核病的试剂成为可能。 它们可以用于例如皮肤试验,血清诊断试验和特异性结核病疫苗的开发。
