The present invention provides a fast and simple method for preparing a microbial profile of a human skin sample. The method can be performed using only portable devices, allowing for in-field profiling. The method is robust and has been found to work even with low DNA quantities and under difficult conditions.

The present invention relates to a method for determining whether an HLA allele is lost in a tumour in a subject, wherein said method comprises the step of determining the specific copy number of said HLA allele in said tumour. The invention also relates to a method for treating cancer in a subject, comprising targeting a neoantigen which is predicted to be presented by an HLA molecule encoded by an HLA allele which has been determined not to have been lost in a tumour in said subject.

The present invention relates to a method which prevents undesirable binding of ddNTPs to double stranded polynucleotides when in the presence of a polymerase. Such methods may be used to prevent the appearance of false positives in methods employing ddNTPs, e.g. in sequence detection methods. The present invention also provides a method of avoiding a false Tm reading or false FRET effects (such as false positive quenching), for example in a melting curve analysis method. In particular a method is provided in which a target nucleotide sequence in a test polynucleotide is detected using a method in which a double stranded molecule is generated which may or may not comprise two labels depending on whether the target sequence is present in which the presence of the two labels is determined, preferably by performing a melting curve analysis.

A method for sequencing a nucleic acid strand, comprising the steps of: providing a solution containing truncated strands having lengths different from one another terminating with a respective dideoxynucleotide from among ddATP, ddTTP, ddGTP, and ddCTP; functionalizing first masses by a donor molecule and second masses by an acceptor molecule such as to generate a light emission when they come into mutual contact; coupling a first mass to a first end of each truncated strand; coupling the second masses to a respective terminal dideoxynucleotide of each strand; applying an AC electrical field having variable frequencies that are such as to generate, on each second mass, a net movement directed towards the first mass; acquiring a plurality of light radiations for each frequency value; and associating each light radiation acquired to a respective dideoxynucleotide and, thus, to a respective nucleotide base.
