Product Highlights
  • High specificity to E. coli O26, minimal cross-reactivity to other E. coli serogroups
  • Polyclonal antibody yields higher sensitivity than monoclonal antibodies
  • Standardized lots provide consistent performance

BacTrace® Anti-Escherichia coli O26 Antibody is isolated from a serum pool of goats immunized with heat-killed whole cells of E. coli serogroup O26. This antibody demonstrates minimal cross-reactivity to other E. coli serogroups. Certain strains of the E. coli serogroup O26 are considered to be STECs (shiga toxin-producing E. coli). The antibody is conjugated with DyLight 488, a brighter, more photostable alternative to FITC and Cy dyes. It can be used in a variety of immunoselection and immunodetection applications.

The plot depicts OD values from a TMB-detected HRP capture ELISA. KPL heat-killed positive controls from various STEC serogroups and S. typhimurium (1:100 dilution, ~107 CFU/mL) were used as analytes. Unlabeled Anti-E. coli O26 antibody (KPL catalog no. 01-95-92) was used as the capture antibody and HRP-labeled conjugate (KPL catalog # 04-95-92) was used as the reporter. All other assay components were KPL catalog products. This study demonstrates the high specificity of BacTrace Anti-E.coli O26 in an ELISA.
