Stability of Dot-ELISA strips
The stability of the dotted strip was assessed with a panel of three
positive and three negative control sera after storage at 4 °C and 37 °C
at 2, 4, 6 months of time period. The results showed clear
differentiation of the dots at both 4 °C and 37 °C storage temperatures
for up to 6 months without losing their reactivity to positive serum
samples (Fig 5).
