Recombinant Protein
The whole rabbit serum used to produce this IgG fraction antibody was prepared by repeated immunizations with recombinant human IL-1a produced in E.coli.  The MW of the recombinant IL-1a was 17,000.  This is the cleavage site generated by the IL-1b converting enzyme (ICE, capase-1).
This antibody is primarily directed against the 17,000 MW human IL-1a and is useful in determining its presence in various assays.  In general, this antibody also detects primate IL-1a in the same formats using similar dilutions.  The antiserum does not recognize human IL-1b or Mouse or Rabbit IL-1a.  In ELISA formats and other immunoreactive assays, this antibody will recognize both the mature 17,000 MW IL-1a as well as the 31,000 MW IL-1a precursor in either non-denatured (native) or denatured samples.  Unlike the IL-1b precursor, the native precursor of IL-1a is recognized by the antibody produced to the 17,000 MW form.   The 31,000 precursor of IL-1a is biologically active and is found primarily intracellularly.  The precursor of IL-1a, unlike that of IL-1b, is biologically active when applied to cells and is thought to have a role as a functional molecule intracellularly and can be found constitutively expressed in various cell.  This antibody is also useful for neutralization of human and primate IL-1a activity in bioassays.  It does not neutralize the biological activity IL-1b.  It does not neutralize the biological activity of mouse, rat or rabbit IL-1a.  It will neutralize primate IL-a.  For neutralization, it is recommended to incubate the sample with a 1:100 dilution of the antibody for at least 4 hours before being tested.  A control of similarly diluted normal rabbit IgG is recommended.  This antibody can be used for FACS analysis.  Caution should be exhibited as the F( c) domain of the rabbit IgG molecule may interact with cells non-specifically.

Application Details

This IgG fraction antibody of anti-Human IL-1a has been tested for use in immunoblotting. This antibody is suitable for use in ELISA, neutralizations, immunohistochemistry, and flow cytometry. It recognizes the 17,000 MW mature IL-1a.  Reactivity in other immunoassays is unknown.
