Quantitative measurement of human IFN-α by ELISA.

<p>Cord blood from 18 LBW and 18NBW newborns and peripheral blood from 8 adults were cultured with R-848 for 18 hrs and IFN-α released in culture supernatant was measured. There was significant difference in the production of IFN- α between LBW vs NBW newborns and adults (p<0.05).
