Abstract

Przedmiotem wynalazku jest sposób wyznaczania nieznanego stezenia Cs czasteczek w próbce o znanej objetosci Vs, obejmujacy nastepujace kroki: a) utworzenie ze wspomnianej próbki N zbiorów rozdzielnych pod-objetosci, zwanych bibliotekami, przy czym w kazdy zbiór ma liczebnosc N' i>0 i w ramach kazdego zbioru wartosc wyrazenia divi jest ustalona, poprzez mieszanie przynajmniej czesci próbki z pewna objetoscia roztworu odczynników wymaganych do przeprowadzenia reakcji wzmocnienia obecnosci przynajmniej jednej poszukiwanej czasteczki do mierzalnego sygnalu, gdzie: vi oznacza objetosc danej pod-objetosci, di>0 oznacza wspólczynnik rozcienczenia, to jest stosunek stezenia Ci czasteczek w danej pod-objetosci do nieznanego stezenia Cs czasteczek w próbce, di - Ci/Cs, zas i jest numerem biblioteki, przebiegajacym liczby calkowite od 0 do N-1; b) przeprowadzenie w kazdej tak uzyskanej pod-objetosci kazdej biblioteki procesu wzmocnienia obecnosci co najmniej jednej wspomnianej czasteczki do mierzalnego sygnalu; c) pomiar wspomnianego sygnalu w kazdej pod-objetosci i odwzorowanie zmierzonego sygnalu w postaci liczby, wektora, macierzy lub tensora dowolnego rzedu, okreslajacego mikrostan ?, w którym indeksy jednoznacznie identyfikuja poszczególne pod-objetosci o zadanym wspólczynniku rozcienczenia di i o zadanej objetosci vi, a wartosci skladowych o zadanym zestawie indeksów odwzorowuja wartosc sygnalu z tej pod-objetosci; charakteryzujacy sie tym, ze nieznane stezenie Cs czasteczek w próbce oblicza sie jako estymate bedaca funkcja wspomnianej liczby, wektora, macierzy lub tensora dowolnego rzedu, otrzymanej w kroku c) i okreslajacej mikrostan ?: E(Cs) = f(?), przy czym co najmniej dwie sposród bibliotek utworzonych w kroku a) róznia sie od siebie wartoscia wspólczynnika modulacji zi, równemu ilorazowi zi = (vidi)/(v0d0).The subject of the invention is a method of determining the unknown concentration of Cs of particles in a sample of known volume Vs, comprising the following steps: for each set, the value of the expression divi is determined by mixing at least a part of the sample with a certain volume of the reagent solution required to carry out the amplification reaction of the presence of at least one molecule of interest to the measurable signal, where: vi is the volume of a given sub-volume, di> 0 is the dilution factor, then is the ratio of the concentration Ci of the molecules in a given sub-volume to the unknown concentration of Cs of the particles in the sample, di - Ci / Cs, and is the library number running integers from 0 to N-1; b) performing in each so obtained sub-volume of each library a process of amplifying the presence of at least one said molecule for a measurable signal; c) measuring the said signal in each sub-volume and mapping the measured signal in the form of a number, vector, matrix or tensor of any order, defining a microstate, in which the indices uniquely identify individual sub-volumes with a given dilution factor di and with a given volume vi, a component values with a given set of indexes map the signal value from this sub-volume; characterized by the fact that the unknown Cs concentration of molecules in the sample is calculated as an estimate being a function of said number, vector, matrix or tensor of any order obtained in step c) and determining the microstate?: E (Cs) = f (?), where at least two of the libraries created in step a) differ in the value of the modulation coefficient zi, equal to the quotient zi = (vidi) / (v0d0).
