METHOD FOR DIAGNOSING DISEASES USING MULTIPLEX FLUORESCENCE AND SEQUENCING
The present invention relates to methods for diagnosing a disease by determining via multiplex fluorescence in situ hybridization (FISH) whether or not mRNA species and/or at least one miRNA species of disease-associated biomarkers ar present in a sample obtained from a subject, and by determining by multiplex sequencing whether or not said mRNA species of disease-associated biomarkers and/or said miRNA species of disease-associated biomarkers of step (a) are present in said sample. The present invention also relates to kits for performing the methods for diagnosis as described and provided herein as well as use of such kits for performing the methods for diagnosis as described and provided herein.
CELL EXTRUDER AND CELL EXTRUSION METHOD
A cell extruder of the present invention comprises: a pressure vessel in which a sample is dispensed; a regulator for adjusting a set pressure of nitrogen gas injected into the pressure vessel and then maintaining a constant pressure; an input valve for opening and closing the injection of nitrogen gas into the pressure vessel; an exhaust valve for removing the internal pressure of the pressure vessel; a filter holder which is provided with a membrane filter soaked with a reagent, so that the sample in the pressure vessel is fed through by the nitrogen gas and crushed into extracellular vesicles; and a collection container in which the extruded sample is stored. According to the present invention, pressure can be freely adjusted by the regulator. That is, the flow rate of the membrane according to pressure can be controlled, thus allowing the validation of a biopharmaceutical production method using an extracellular vesicle extruder. In addition, during cell extrusion, a sintered disc can be removed and cells can be extruded by using only a membrane. Vesicles can be produced within a fine pressure adjustment range (at a fine low pressure at which the membrane is not torn) in which no sintered disc is required.
METHOD TO PREPARE A SAMPLE FOR ATOM PROBE TOMOGRAPHY (APT), PREPARATION DEVICE TO PERFORM SUCH METHOD AND METHOD TO INVESTIGATE A REGION OF INTEREST OF A SAMPLE INCLUDING SUCH PERFORMING METHOD
To prepare a sample for atom probe tomography, a raw sample body having a surface and a region of interest (ROI) to be inspected by APT is provided. Pillars containing the ROI are formed into the surface of the raw sample body via ablation of material of the raw sample body from the surface with an ultra-short pulsed laser. Redeposited ablated material is removed in the region of the formed pillars. The surface of the formed pillars is polished. A preparation device to perform such a preparation method includes a sample handling unit, a pillar forming unit including an ultra-short pulsed laser, a removal unit to remove redeposited ablated material, and a polishing unit. The result is an efficient preparation of robust samples for atom probe tomography. To investigate a region of interest of a sample, the preparation method is performed and then atom probe tomography of the region of interest is performed.
Mass spectrometry histochemistry of peptides from formaldehyde-fixed, paraffin-embedded tissue
The present invention in general relates to a method of localization and structural characterization of peptides in a formaldehyde-fixed paraffin-embedded biological sample using matrix assisted ionization (such as in MALDI). Specifically, the invention relates to the combination of the development of a sample preparation protocol which does not require any enzymatic digestion nor antigen-retrieval steps, with highly sensitive mass spectrometry.
