[The RH-PA cell line--a source for obtaining the urokinase-type plasminogen activator]

Autor: M A, Kapina, M G, Zelenin, L A, Glukhova, B B, Egorov

Publikováno v: Antibiotiki i khimioterapiia = Antibiotics and chemoterapy [sic]. 34(12)

A new cell line (RH-PA) was established on the basis of the human embryonic kidney cell line (RH). The new line produces urokinase type plasminogen activator (PA). The activity of the activator amounted to 150-200 IU/ml estimated with the procedure o

[Scanning electron microscopy of metaphase chromosomes. I. The relation of chromosome morphology to the method of drying the preparations]

Autor: M G, Zelenin

Publikováno v: Tsitologiia. 24(10)

The surface of metaphase chromosomes fixed in methanol--acetic acid (3 : 1) has been examined by high resolution scanning electron microscopy. The chromosomes were prepared both by the standard method (spread on the slide) and as isolated cells. The

[Screening of human and animal tissue cell cultures as potential producers of plasminogen activator]

Autor: M A, Kapina, M G, Zelenin, B B, Egorov

Publikováno v: Antibiotiki i meditsinskaia biotekhnologiia = Antibiotics and medical biotechnology. 31(10)

Twenty six normal cell cultures and 19 tumor cell cultures were subjected to screening for plasminogen activator (PA), a fibrinolytic enzyme. It was shown that the enzyme production depended on the nature, origin, type and species of the tissue cultu

[A study of the cloned human erythropoietin gene expression in mammalian cells in vitro]

Autor: I A, Kramerov, M G, Zelenin, N S, Filiakina, S L, Kolobkov

Publikováno v: Molekuliarnaia genetika, mikrobiologiia i virusologiia. (3)

The human gene coding for the principal factor of erythroid cells differentiation, erythropoietin, has been isolated from the genomic phage library using an oligonucleotide probe for the gene. The construction of series of plasmids carrying the eryth

[Sensitive method of detecting 5-bromodeoxyuridine differentially incorporated into the chromosomes of mammals]

Autor: V A, Beniush, M G, Zelenin

Publikováno v: Biulleten' eksperimental'noi biologii i meditsiny. 95(4)

A modified method for fluorochrome staining with acridine orange of chromosome preparations for revealing the BUdR label is described. It has been shown that the alkaline medium used increases the contrast between chromosome areas with varying BUdR c

[Morphological changes in isolated metaphase chromosomes depending on the pH and ionic strength of the solutions]

Autor: M G, Zelenin, A F, Zakharov

Publikováno v: Tsitologiia. 24(4)

The morphology of isolated unfixed Chinese chamster chromosomes is described in relation to the composition of solutions used for chromosome isolation. The chromosomal morphology was studied with the aid of a flow-chamber and phase-contrast microscop
