ii) в каждом отличающемся условии селективности присутствуют тот же самый адсорбент и другой элюант, и
iii) обработка образца при определенном условии селективности включает приведение образца в контакт с адсорбентом, связанным субстратом, и промывку адсорбента элюантом с целью удержания аналита в образце с помощью адсорбента;
б) определение аналитов в первом образце путем:
i) параллельной обработки первого образца при каждом из различных условий селективности, и
ii) определения аналитов, удержанных адсорбентами, с помощью масс-спектрометрии, при этом масс-спектрометрия включает десорбцию и ионизацию аналита из адсорбента с помощью источника энергии и обнаружение десорбированных и ионизированных аналитов с помощью детектора;
в) определение аналитов во втором образце путем:

ii) определения аналитов, удержанных адсорбентами, с помощью масс-спектрометрии, а также
г) сравнение аналитов, обнаруженных в первом биологическом образце, с аналитами, обнаруженными во втором биологическом образце, с целью идентификации аналитов, которые дифференциально представлены в первом и втором биологическом образце.25. A method for identifying analytes that are differentially represented in the first and second biological samples, comprising the following steps:
a) the choice of many different conditions of selectivity in which the first and second samples are processed, in which
i) each selectivity condition is determined by a combination of adsorbent and eluant
ii) in each different selectivity condition, the same adsorbent and a different eluant are present, and
iii) treating the sample under a certain selectivity condition includes contacting the sample with an adsorbent bound to the substrate and washing the adsorbent with eluant to retain the analyte in the sample using the adsorbent;
b) determination of analytes in the first sample by:
i) parallel processing of the first sample under each of the various conditions of selectivity, and
ii) determining analytes retained by adsorbents using mass spectrometry, wherein mass spectrometry includes desorption and ionization of the analyte from the adsorbent using an energy source and detection of desorbed and ionized analytes using a detector;
c) determination of analytes in the second sample by:
i) parallel processing of the second sample under each of the various conditions of selectivity, and
ii) determination of analytes retained by adsorbents using mass spectrometry, and
d) comparing the analytes found in the first biological sample with the analytes found in the second biological sample in order to identify analytes that are differentially represented in the first and second biological sample.
28. Способ по п. 25, отличающийся тем, что этап сравнения аналитов, обнаруженных в первом и втором образце, производится с помощью программируемого цифрового компьютера.27. The method according to p. 25, wherein the biological samples include first and second cell extracts
28. The method according to p. 25, characterized in that the step of comparing the analytes found in the first and second sample is performed using a programmable digital computer.
