Recombinant Mouse Anti-IAV HA1 Antibody (26/9) (CAT#: PABZ-076)

Recombinant Mouse Antibody (26/9) is capable of binding to IAV HA1, expressed in Chinese Hamster Ovary cells (CHO). This antibody recognizes the same six-residue epitope of an immunogenic peptide from influenza virus hemagglutinin (HA1; 75-110).

Figure 1 Binding of mAb 26/9 to substitution analogs of the control peptide Ace-YPYDVPDYASLRS-NH2.

Direct ELISA experiments (A) using mAb 26/9 and substitution analogs in positions -DVPDYAS- are shown graphically. The percentage inhibition of the control peptide is plotted against the amino acid substitution at each position in the epitope. The table in B shows the IC₅₀ and RF values calculated from the competitive ELISA experiments for 26/9.
