  • Relevance
    Flagellin (FliC) is a subunit protein that polymerizes (along with other proteins) to form the filaments of bacterial flagella. Assembly of the bacterial flagellum occurs in a precise, temporal order where the basal component (FlgE, FlgK, and FlgL are assembled inside the bacterial membrane, followed by exportation of the filament cap protein FliD, and secretion of about 20,000 flagellin monomers (FliC) through the channel. FliC monomers are polymerized to form the tail filament. FliC monomers can function as pathogen-associated molecular patterns (PAMPs), and can be detected by host cells through surface-localized toll-like receptor 5 (TLR5) and cytosolic Nod-like receptors (NLRs).

    Thank you for contacting us.

    The flagellin antibody was generated against recombinant purified
    full-length FliC from E Coli DH5a. There are similarities at the N and C
    termini with P aeruginosa FliC but it is probably not enough fo...

    Thank you for contacting Abcam. The concentration of protein in ab93713 is between 30 and 40 mg/ml. We do not know how much of that total is made up with antibody because the sample is serum, not purified antibody. Please let me know if there is anythi...

    Thank you for contacting us. The total protein concentration of ab93713, lot GR35089-1, is around 30-40 mg/ml. However, since this is whole serum containing a wide variety of proteins, the concentration of the specific anti-Flagellin antibody canno...
