  • Product name
    Anti-Francisella tularensis LPS antibody [FB11]
  • Description
    Mouse monoclonal [FB11] to Francisella tularensis LPS
  • Specificity
    ab2033 recognises LPS of virulent and vaccine strains of Fr. tularensis. There is no cross-reactivity  with Fr. Novicida, Br. abortus, Br. suis, Br. melitensis, Br. ovis, Y. pestis, Y. enterocolitica, Y. pseudotuberculosis, E.Coli, V. cholerae, B.neotomae, S.typhimurium.
  • Tested applications
    Suitable for: WB, ELISA, ICC/IFmore details
  • Immunogen

    Spleen cells of Balb/c mice were immunised with purified F.tularensis strain 15 LPS.

  • Epitope
    The binding site for ab2033 is located on the O-antigen polysaccharide chain which consists of tetrasaccharide fragments and has the following structure: -4)-D-GalpNAcAN-(1-4)--D-GalpNAcAN-(1-3)--D-QuipNac-(1-2)--Quip4NFm-(1. Tetrasaccharide D-GalpNAcAN-(1-4)--D-GalpNAcAN-(1-3)--D-QuipNAc-(1-2)--D-Quip4NFm and trisaccharide D-GalpNAcAN-(1-3)--D-QuipNAc-(1-2)--D-Quip4NFm compete in ELISA for binding MoAb FB11 with LPS of Fr. tularensis.

  • Relevance
    Francisella tularensis is a small, nonmotile, aerobic, gram-negative coccobacillus. It has a thin lipopolysaccharide-containing envelope and is a hardy non–spore-forming organism that survives for weeks at low temperatures in water, moist soil, hay, straw, and decaying animal carcasses. Lipopolysaccaride (LPS) is a main species-specific antigen of Francisella tularensis. According to the data available LPS of tularemia microbe differs from LPS of other gram-negative bacteria. LPS of tularemia microbe hasn’t yet revealed the properties of classical endotoxin, which may be connected with non-typical structure of lipid A – a toxic component of LPS.

Thank you for your inquiry.

We would not recommend ab97234 as a secondary for ab2033 because they do not match in isotype. The secondary ab97234 targets Mouse IgA, but the primary ab2033 is IgG2a.

I would reccomend using...
