A: RT-qPCR measurements of RNA isolated from VLP-spiked serum samples that was prepared using IFAST and frozen immediately, raw sample stored at 37°C for 1 day, 1 week, or prepared via IFAST and then stored at 37°C for 1 week. B: Viral loads were quantified from VLP-spiked serum samples using IFAST as the RNA extraction method, allowing comparison of actual (spiked) values with the measurements. C: Viral loads were quantified from serum spiked with unmodified subtype B HIV, again using IFAST as the extraction method. Error bars represent ±1 SD.
