Biotechnology -- Requirements for evaluating the performance of quantification methods for nucleic acid target sequences -- qPCR and dPCR

Status: Gällande

Som en följd av coronautbrottet tillgängliggör vi nu kostnadsfritt ett antal europeiska och globala standarder som företag och organisationer kan använda i samband med bekämpningen av covid-19-pandemin.

Denna standard är därmed tillgänglig kostnadsfritt under en begränsad period via SIS Abonnemang, läs mer och få tillgång till standarden här >>

Preliminärt kommer abonnemanget att erbjudas med kostnadsfri tillgänglighet till 31/3 2021. Därefter kommer samtliga standarder vara tillgängliga som vanligt för köp på sis.se.

Omfattning
This document provides generic requirements for evaluating the performance and ensuring the quality of methods used for the quantification of specific nucleic acid sequences (targets).
This document is applicable to the quantification of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) target sequences using either digital (dPCR) or quantitative real-time PCR (qPCR) amplification technologies. It applies to target sequences present in nucleic acid molecules including double-stranded DNA (dsDNA) such as genomic DNA (gDNA) and plasmid DNA, single stranded DNA (ssDNA), complementary DNA (cDNA), and single stranded RNA (ssRNA) including ribosomal RNA (rRNA), messenger RNA (mRNA), and long and short non-coding RNA [microRNAs (miRNAs) and short interfering RNAs (siRNAs)], as well as double-stranded RNA (dsRNA).
This document applies to nucleic acids derived from biological sources such as viruses, prokaryotic and eukaryotic cells, cell-free biological fluids (e.g. plasma or cell media) or in vitro sources [e.g. oligonucleotides, synthetic gene constructs and in vitro transcribed (IVT) RNA].
This document is not applicable to quantification of very short DNA oligonucleotides (<50 bases).
This document covers:
— analytical design including quantification strategies (nucleic acid copy number quantification using a calibration curve as in qPCR or through molecular counting as in dPCR, quantification relative to an independent sample and ratio measurements) and use of controls;
— quantification of total nucleic acid mass concentration and quality control of a nucleic acid sample including assessment of nucleic acid quality (purity and integrity);
— PCR assay design, optimization, in silico and in vitro specificity testing;
— data quality control and analysis including acceptance criteria, threshold setting and normalization;
— method validation (precision, linearity, limit of quantification,...
