摘要:
A method of multi-color labeling at least two antigens present in a tissue such as non-liquid tissue or body fluids, with the aid of different antibodies is improved by introducing between the labeling of the first antigen and the labeling of the second antigen, and between labeling of the second and that of any further antigen, at least once a treatment with a non-immune normal serum and optionally other agents blocking any binding sites remaining free in the tissue after a last-preceding labeling step.
摘要:
Apparatus for measurement of the reception time of a pulse in a receiving system, which contains at least one receiving channel with a non-linear transmission response, which receiving channel produces at its output a received signal, having a memory, in which the received signals of reference pulses with a predetermined different amplitude are available as reference signals with respect to a time scale, and having an evaluation device, which is connected to the receiving system and to the memory and compares a received signal with each reference signal with a variant time offset in order to determine that reference signal and that time offset for which the comparison discrepancy is a minimum, and outputs this time offset as the reception time with respect to the time scale.

摘要:
This invention relates to a process for identifying and enriching cell-specific target structures, in particular for the identification of cell-specific protein combination patterns on the surface of cells and for enriching such cells. The process comprises depositing a heterogeneous cell mixture one or plural surfaces with predefined structures causing cells with corresponding target structures to become bound to such surface(s), removing any non-binding cells of said cell mixture from said surface, identifying the cell-specific target structures responsible for the binding of the cells to said surface(s), selecting and enriching cells with identical cell-specific target structures on said surface(s), and biochemically characterizing the target structures.
摘要:
The present invention is directed to a method of blocking the cytotoxic activity of Fc&ggr;RIII receptor-positive immune cells in a patient with amyotrophic lateral sclerosis using an effective amount of soluble Fc&ggr;RIII receptors. The soluble Fc&ggr;RIII receptors of the invention are specific for immunoglobulin G of under-class 1 (IgG1) and/or 3 (IgG3).
摘要:
The present invention is directed to a method of blocking the cytotoxic activity of Fc&ggr;RIII receptor-positive immune cells in a patient with amyotrophic lateral sclerosis using protein V specific for IgG1 and/or IgG3. In one aspect of the invention, protein V blocks the binding of IgG1 and/or IgG3 to the Fc&ggr;RIII receptor, which inactivates the receptor, and destroys cellular forms containing the receptor.
