Recombinant Mouse Anti-Influenza A Antibody Fab Fragment (S139) (CAT#: PABX-118-F (E))
Anti-Influenza A antibody is a Mouse of Fab class that binds to an Influenza A. This antibody was the first antibody to be described with heterosubtypic reactivity, neutralizing strains from multiple subtypes, such as H1, H2, H3, and H13, that cross the HA group barrier.

Figure 1 SDS-PAGE analysis of purified S139/1 IgA and IgG antibodies.
Equal amounts (2.5 mg) of purified S139/1 IgA and IgG antibodies were analyzed by SDS-PAGE under reducing conditions (5%–20% gradient gel) (A). Polymeric forms of purified S139/1 IgA and IgG antibodies (5 mg) were analyzed under nonreducing conditions (3%–10% gradient gel) (B).

Figure 2 Comparison of binding activities of S139/1 IgA and IgG antibodies.
Binding activities of S139/1 IgA (continuous lines) and IgG (dashed lines) were tested in ELISA. Disrupted viral particles of Aichi/H3, WSN/H1, Adachi/H2, and Maryland/H13 were used as antigens. Data are mean values of duplicate wells. EC50 values calculated based on the ELISA data are shown in Table 1.

Figure 3 Comparison of neutralizing activities of S139/1 IgA and IgG antibodies.
Appropriately diluted viruses were mixed with S139/1 IgA (continuous lines) or IgG (dashed lines) at the indicated dilutions. Neutralizing activities were evaluated by counting the number of plaques formed on MDCK cells. IC50 values calculated based on the neutralization curves are shown in Table 3.
