Serum Dried Samples to Detect Dengue Antibodies: A Field Study

Figure 1

Standardization of sample elution. (a) Absorbance of eluates at 280 nm in samples incubated either at 2 h (empty bars) or overnight (ON, shaded bars) using different eluate volumes. (b) Absorbance of eluates incubated at either 4°C or room temperature (RT). (c) Absorbance of ten independent control samples eluates at different elution volumes.
