This product is a recombinant Human antibody that can recognize SFTSV GN. MAb 4-5 is a human-origin, neutralizing monoclonal antibody targeting Gn, showing cross-neutralizing activity to a wide range of SFTSV isolates in China. The MAb 4–5 can recognize the denatured SFTSV Gn head but not the RVFV Gn head by Western blot.
Figure 1 Neutralization potency of MAb 4–5 to SFTSV.
A human monoclonal antibody (13C6) against Ebola was used as a negative control.

Figure 3 Characterization of MAb 4-5 IgG1 in IFA.
Infected (A, B) and noninfected (SFTSV, JS-2010-003) (C, D) Vero cells were fixed on slides and incubated with MAb 4-5 IgG1 (A, C) or an irrelevant human IgG1 (B, D). Bound antibodies were detected by using FITC-conjugated anti-human antibody with PBS dilution buffer (pH 7.4) containing 0.01% (wt/vol) Evens blue counterstain.
