NIAID RSVF2-5
NIAID RSVF2-5 is a human monoclonal antibody fragment. NIAID RSVF2-5 binds to conserved, distinct conformational epitopes on RSV fusion glycoprotein, and shows activity against RSV subgroup A and B strains. NIAID RSVF2-5 reduces pulmonary and lung viral titers in RSV-infected rodents. NIAID RSVF2-5 can be used for the research of respiratory syncytial virus infection.

NIAID RSVF2-5 neutralizes RSV Tracy (subgroup A) and RSV 18537 (subgroup B) in HEp-2 cells with IC50 values of 3.6 μg/mL and 1.8 μg/mL, respectively[2].
NIAID RSVF2-5 neutralizes RSV A2 (subgroup A) in HEp-2 cells with an IC60 of 0.07 μg/mL[2].
NIAID RSVF2-5 binds to purified RSV A2 strain gF protein with a KD of 4.9 × 10-10 M[2].
