The invention generally relates to compositions for maximizing capture of affinity-labeled molecules on solid supports. The disclosed methods and compositions were developed to maximize depletion of ribosomal RNA from total RNA samples, which is useful to improve the quality of RNA preparations used for applications such as massively parallel sequencing. The RNA depletion method is based on using long affinity-labeled RNA molecules that are complementary to all or part of the target ribosomal RNAs, as subtractive hybridization probes.

The present disclosure is related to methods and materials for depleting unwanted RNA species from a nucleic acid sample. In particular, the present disclosure describes how to remove unwanted rRNA, tRNA, mRNA or other RNA species that could interfere with the analysis, manipulation and study of target RNA molecules in a sample.

Embodiments of a method and/or system can include generating a co-amplified mixture based on co-amplifying a set of nucleic acid molecules (e.g., cell-free nucleic acids, etc.) from the biological sample, wherein the set of nucleic acid molecules includes a genomic region of interest associated with the medical condition; and a homologous native genomic region with partial sequence similarity to the genomic region of interest; sequencing the co-amplified mixture; determining an abundance metric for the genomic region of interest and an abundance metric for the homologous native genomic region; and/or facilitating the characterization of the medical condition based on the abundance metric for the genomic region of interest and the abundance metric for the homologous native genomic region.
