  • Concentration information loading...
  • Purity
    Protein A purified
  • Purification notes
    This product was prepared from monospecific antiserum by immunoaffinity chromatography using cecropin B coupled to agarose beads followed by solid phase adsorption(s) to remove any unwanted reactivities. Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-Rabbit Serum and purified and partially purified cecropin B. Reactivity against other forms of cecropins has not yet been determined.

  • Relevance
    Cecropins are produced by insects, particularly under conditions of infection. Cecropins are bioactive peptides that exhibit activities by interacting with membranes and forming transmembrane channels that allow the free flow of electrolytes, metabolites and water across the phospholipid bilayers. Cecropins A, B and D are close homologues consisting of 35-39 residues. They are found in the pupae of the cecropin moth, but related homologues named lepodopteran, bactericidin, moricin and sarcotoxin are produced by other insects.

    Thank you for your inquiry.

    We do not have confirming data for possible reactivity of this antibody with Cecropin A. The statement was based on sequence homology only.

    I'm sorry I could not be of further assistance in this instance....
