We also expanded our RT-caPCR assay to test for more RNA targets by including 3 additional primer sets and 4 probes to test for influenza A and B (2 targeting the M1 matrix protein gene of influenza A17 and 2 targeting nonstructural protein-1 (nsp1) in the Yamagata and Victoria lineages of influenza B18). Here, SH2D3A is linked to influenza.
