Accurate quantification of DNA content in DNA hydrogels prepared by rolling circle amplification

Abstract

Accurate quantification of polymerized DNA in rolling circle amplification (RCA)-based hydrogels is challenging due to the high viscosity of these materials, however, it can be achieved with a photometric nucleotide depletion assay or qPCR. We show that the DNA content strongly depends on the template sequence and correlates with the mechanical properties of the hydrogels.
