5550033 Mold plunger and method for embedding tissue samples
PATENT ABSTRACTS
423
The present invention provides a novel method for expression of high levels of heterologons proteins in Drosophila cells.
5550032 BIOLOGICAL ASSAY FOR MICROBIAL CONTAMINATION
5550051 Isbister Jeuefir Potomac, MD, UNITED STATES Assigned to George Mason University Methods and kits for detecting the presence of and quantifying the concentration of viable microorganisms in a liquid sample are provided. Enzymes pReamt in viable microorgansims nxluce an indicator reagent to produce a visible color change. N o tilrations or dilutions of the sample are necessary. Vmintions of the test are described which can be used to detect a threshold level of viable microorganisms, to detect the presence or absonce of viable microorgnnisms and to quantify the concentration of viable microorganisms in a liquid sample. The results are obtained rapidly with those for the detection available within thirty m i n u ~ and those for the quantification available within thirteen hours.
5550033 MOLD PLUNGER AND METHOD FOR EMBEDDING TISSUE SAMPLES
Mundt Wolfgang; Woehrer Wilfrie; Domer Friedric; Eibl Johann Vienna, AUSTRALIA Assigned to Immuno Aktiengesellschaft The invention relates m a biomass for producing vires/vires antigen, which consists of cell aggmgat~ of avian embryo cells having diameters of between 100 mum and 1,000 mum. The biomass according to the invention has a high metabolic activity in suspension in the culture medium and is infected with virus. It enables the large-scale production of pure virus/vires antigen and is particularly suitable for the production of TBE-vims/vims antigen.
5550060
Kmmdi~k Carlos Birmingham, AL, UNITED STATES A method and apparatus for preparing tissue samples for subsequent sficing in a microtone, utilizing a thermally transmissive body and removable mold heads to facilitate encapsulation of tissue samples in a gelatinous substance so that the samples may be selectively oriented for proper slicing in the microtone.

METHOD AND PROCEDURE FOR PREPARING RED BLOOD FRACTIONS Sannders Alexander; Summerfield Frank W; Zarowitz Michael A San Carlos, CA, UNITED STATES Assigned to Chronomed Inc Methods and apparatus for separating red blood cells by density are described. Older red blood cells are more dense than younger ones. Certain changes in the physiology are reconted in changes in hemoglobin or the red blood cells. By assaying diffesent aged red blood cells, one can determine the historical physiological changes over a period of many weeks. Improved separation of red blood cells is accomplished by using rigid capillary tubes having an inner surface which augments the density equilibrium of red blood cells and/or intae~entally increasing the centrifugation forces, as well as by chemically treating red blood cells to
