A method for synthesizing an antiserum for rapid-turnaround therapies includes collecting antibody-secreting cells from a test subject, wherein the test subject has been exposed to a target biological agent and has produced an antibody response; selecting a subset of the antibody-secreting cells, the subset of the antibody-secreting cells producing antibodies that neutralize the target biological agent; generating variable-region-coding DNA sequences from the antibodies that neutralize the target biological agent; tagging amplicons of the variable-region-coding DNA sequences with unique nucleic acid identifiers to associate the variable-region-coding DNA sequences derived from individual ones of the subset of the antibody-secreting cells; analyzing antibody-type distribution in a natural immune response; synthesizing antibodies from the variable-region-coding DNA sequences to form synthetic antibodies; and mixing the synthetic antibodies in a proportion equal to the antibody-type distribution in the natural immune response to form the antiserum.

A method for limited input whole genome sequencing of RNA viruses includes isolating a viral RNA sample, converting the viral RNA sample to a double-stranded viral cDNA sample, constructing a double-stranded viral cDNA amplicon library from the double-stranded viral cDNA sample, and sequencing the double-stranded viral cDNA amplicon library to obtain a double-stranded viral cDNA sample sequencing read.
