Long-term iSDA reagent stability in the Std 17 GF. (a) Normalized intensity of the LF test line after dry storage at 22 °C at different times. (b) Images of lateral flow detection strips at various time points. “C” indicates the control line, and “T” is the test line for ldh1 assay on the detection strips. (c) Corresponding gel images of the ldh1 amplicon products (indicated by arrow) at various time points. NTC is no template control. The iSDA reagents in the presence of 10% trehalose and 2.5% dextran performed well after 12 months of dry storage, with signal intensities similar to that observed with fresh reagents.
