摘要:
The invention relates mainly to a method for processing a plurality of spectral datasets (J1-Jn) intended for being used by a molecular imaging method or a method for recording a plurality of spectral datasets (J1-Jn), each spectral dataset (J1-Jn) being defined by a set of spatial positions (Xi, Yj) each of which is associated with a molecular spectrum with at least two dimensions containing a set of molecular information (S(Xi, Yj)), characterised in that it comprises in particular the following steps: for each dataset (J1-Jn), cutting the molecular spectrum associated with each position (Xi, Yj) into a plurality of spectrum segments (T1-Tm); inserting the segments (T1-Tm) obtained for each position (Xi, Yj) of each dataset (J1-Jn) into a database (BDD); selecting in the database (BDD), following a request relating to molecular information of interest, the one or more segments (T1-Tm) containing the molecular information of interest; and selecting, within each segment (T1-Tm), said molecular information of interest.
摘要:
The invention relates to a method for evaluating whether a molecule of interest binds or is incorporated in at least one target tissue, comprising visualizing and comparing the distribution of the molecule of interest and of at least one control compound within the target tissue or on the target tissue surface of at least one animal that has previously received the molecule of interest and/or the control compound. Advantageously, the distribution of the molecule of interest is visualized and compared with the distribution of positive and negative compounds using mass spectrometry imaging on the surface of the target tissue.
摘要:
The invention relates to a method for preparing a range of dilutions of at least one standard molecule for a tissue, according to which use is made of a ground tissue to which the standard molecule is added, the whole being conditioned and fractionated before the analysis of a fraction of said tissue. The invention also relates to a method for detecting and quantifying at least one target molecule in at least one tissue using a standard range according to the invention.
摘要:
The invention relates to a method for characterising a sample by mass spectrometry imaging (MSI) according to which a spatial arrangement of at least one ion in said sample is characterised from imaging data associated with said ion, in terms of morphology and/or texture.
摘要:
The present invention relates to the field of the detection of molecules of interest in a sample, preferably by mass spectrometry. The present invention concerns a label compound, a molecule labeled with said compound (a conjugate), a method of detection of a molecule of interest (a target molecule) in a sample involving said conjugate, a kit to implement said method and a process for the preparation of the label.
摘要:
The invention relates to a method for identifying and quantifying by mass spectrometry imaging at least one target analyte in a tissue sample, comprising the following steps: a) depositing the tissue sample to be analyzed on a support; b) analyzing the sample by mass spectrometry imaging, so as to obtain the mass spectrum of the target analyte in said tissue sample; c) weighting a signal associated with the mass spectrum of the target analyte in said tissue sample by a tissue extinction coefficient (TEC) specific to the target analyte and to the tissue sample which is obtained by using a control tissue sample; and d) using the weighted signal of the target analyte to determine the quantity of target analyte in the tissue sample.
