    • A delivering member for filtering and delivering a sample to a test assay surface includes a prefilter having a sample receiving surface and a surface for delivering a sample to a test assay surface. The prefilter includes a diffusing material on its receiving surface for rapidly and evenly diffusing a sample across the prefilter receiving surface. In this way, a sample may be rapidly and evenly delivered to a test assay surface. A test assay solid phase has a surface including an area carrying an immobilized species and an area free of immobilized species. When a sample is applied to the surface, followed by application of a labeled species, the evenness of distribution of the labeled species is indicative of the evenness of application of the sample. A kit includes a delivering member and an assay surface.
    • 用于过滤和将样品递送到测试测定表面的递送构件包括具有样品接收表面的预过滤器和用于将样品递送到测试测定表面的表面。 预过滤器在其接收表面上包括扩散材料,用于使样品快速均匀地扩散穿过预过滤器接收表面。 以这种方式,样品可以快速均匀地输送到测试测定表面。 测试测定固相具有包括携带固定化物质的区域和没有固定化物种的区域的表面。 当将样品施加到表面上,随后施加标记物质时,标记物质的分布均匀性表示样品的均匀度。 试剂盒包括递送成分和测定表面。

    • The method disclosed is used for the genetic expression in vivo of heterologous proteins such as the c-ras oncogene of Harvey, the human growth hormone gene (hGH) and the gene resisting to neomycine by means of cells transfected with liposome that is injected as a suspension in the blood circulating in an animal (rat or rabbit). The expression vector encapsulated in the liposomes injected may contain for example the gene coding for an oncogene. In this case, a member containing transfected differentiated cells is taken from the animal and they are then cultivated in vitro in order to select the cells which express the oncogene and which, consequently, may proliferate in vitro. When the animal is injected with liposomes encapsulating the gene of hGH and the neomycine resistant gene, the cells selected in culture media containing the antibiotic produce hGH. On the other hand, when the expression vector contains the gene of hGH controlled by the human promotor of the 70 kd, thermal shock protein gene, and it is injected to animals, the latter secrete in the circulating blood hGH after thermal induction. Furthermore the repetition of these steps induces the synthesis of anti-hGH antibodies by the animal. The main fields of application of the invention are either the production of differentiated cells capable of proliferating in vitro or the production in vivo of biologically active or antigenic heterologous proteins.
    • 所公开的方法用于异源蛋白质如Harvey的c-ras致癌基因,人生长激素基因(hGH)和通过以脂质体转染的细胞抗新世代基因的基因的遗传表达,其被注射为 悬浮在动物(大鼠或兔子)中循环的血液中。 封装在注射的脂质体中的表达载体可以包含例如编码癌基因的基因。 在这种情况下,从动物中取出含有转染的分化细胞的成员,然后在体外培养它们,以便选择表达致癌基因的细胞,并因此在体外可能增殖。 当注射包裹hGH基因的脂质体和新霉素抗性基因时,在含有抗生素的培养基中选择的细胞产生hGH。 另一方面,当表达载体含有由70kd的人类启动子控制的hGH基因的热休克蛋白基因时,其被注射到动物中,后者在热诱导后分泌在循环血液中。 此外,这些步骤的重复诱导动物对抗hGH抗体的合成。 本发明的主要应用领域是生产能够在体外增殖或体内生物活性或抗原异源蛋白质生产的分化细胞。
