    Abstract: Provided herein are methods and systems for absolute quantification of a target 16S rRNA and/or of a target prokaryotic taxon, based on amplifying and sequencing a same 16S rRNA recognition segment in which target 16S rRNA conserved regions flank 16S rRNA variable regions, conserved and variable among a plurality of sample 16S rRNAs and/or of a sample prokaryotic taxon of higher taxonomic rank with respect to the target taxon. In the methods and systems, absolute abundance of the a plurality of sample 16S rRNAs and/or of the sample prokaryotic taxon detected by the amplifying, is multiplied by the relative abundance of the target 16S rRNA and/or of a target prokaryotic taxon detected by the sequencing to provide the absolute quantification in accordance with method and systems of the disclosure.

    Abstract: Methods and systems and related compositions for separating through a solid matrix a mixture comprising a nucleic acid in a concentration of 1 μM or less, together with a target compound having a water solubility equal to or greater than 0.001 g per 100 mL, which can be used for managing fluid flow, biochemical reactions and purification of the nucleic acid or other target analytes. The method comprises contacting the solid matrix with a target compound removing agent having a water solubility equal to or less than 0.05 g per 100 mL at 25° C. at 1 atm pressure with water having a solubility in the removing agent of less than 10 g per 100 mL at 25° C. at 1 atm pressure, the contacting performed to remove the target compound from the solid matrix.
