Abstract: The invention relates to the preparation of plasmids which carry the genes for biosynthesis of L-prolin, one of these genes being mutated in such a way that the allosteric inhibition of the biosynthesis of this amino acid, which usually exists, is no longer present. The invention furthermore relates to the use of these plasmids for developing bacterial strains of the species Escherichia coli which excrete L-prolin into the culture liquid and which are therefore particularly suitable for the preparation of this amino acid by fermentation. The plasmids here can either cause a capability of L-prolin overproduction in the first place, or considerably increase an already existing chromosomally determined capability for overproduction. The invention also relates to the preparation of suitable host cell mutants which, in connection with these plasmids, bring about a particularly high concentration of L-prolin in the culture liquid.

Abstract: Monoclonal antibodies which, in the direct agglutination assay, are specific for human blood group antigen D (Rh0) and hybridoma cell lines which produce these monoclonal antibodies can be prepared by immunising animals, especially mice, with human D-positive erythrocytes and fusing the spleen cells obtained from these animals with animal, especially mouse, myeloma cells with the formation of a hybridoma. The hybridomas are cultured as clones, and the antibodies obtained from the individual clones are tested for their specificity against the blood group characteristic D in human erythrocytes. Clones which produce antibodies with a specificity against the blood group characteristic D of human erythrocytes are selected for further culturing to prepare the antibody, the antibody being obtained from the culture medium or the ascites fluids of the animal, especially the mouse, which carries the hybridoma tumour.

Abstract: An improved means for rapidly compressing, expanding, and displaying broad band information which is transmitted over a narrow band communications channel. In the preferred embodiment, a video image is cyclically assembled in low resolution and high resolution phases from digitized data representing gray level intensity for individual pixels which have been grouped into cells. During the initial cycle of the low resolution phase, a representative sample of said cell intensity values is transmitted by a sending station to a receiving station according to a video compression routine. Said receiving station then uses a video expansion routine to calculate an intensity value for those cells and pixels whose intensity values were not transmitted and displays an initial image. This image is refined during subsequent low-resolution cycles by means of additional transmissions from the sending station which replace the calculated cell intensity values with an actual value for that cell. During the high resolution phase, an error determination routine or external input from a viewer selects those cells containing the greatest deviation in intensity levels from the input video image. The error compression and expansion routines substitute a plurality of individual pixel intensity values for single cell intensity values. 
     The present invention also discloses a means for allowing color capable stations to send or receive color transmissions while retaining the capability to interact with noncolor stations. Color data is compressed and interleaved with black and white data by a color capable sending station and subsequently separated and expanded by a color capable receiving station.
