  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

Specificity and Use

IL-1B / IL-1 Beta antibody was raised against this antibody was prepared by repeated immunizations with recombinant human IL-1 produced in E. coli. The MW of the recombinant 153 aa IL-1 was 17 kD with the N-terminal amino acid at position alanine 117. This cleavage site is generated by the IL-1 converting enzyme (ICE, caspase-1).
This antibody was heated to 56° C for 30 minutes. This is an IgG preparation of whole rabbit serum purified by DEAE fractionation. This antibody is primarily directed against mature, 17000 MW human IL-1beta and is useful in determining its presence in various assays. In general, this antibody also detects primate IL-1beta in the same formats using similar dilutions. The antiserum does not recognize human IL-1a. In ELISA formats and other immunoreactive assays, this antibody will recognize 10% of the non-denatured (native) precursor 31000 MW IL-1beta containing samples but will primarily detect all of the 17000 MW mature molecule. However, in immunoblot analysis of natural cell products or human body fluids, the usual procedure of hearing the sample in SDS with or without reducing agents will facilitate denaturing of the 31000 MW IL- 1beta precursor molecule. Denatured 31000 precursor IL-1beta will be recognized by this antibody but often migrates as a 35000 MW band. This is due to the unfolding of the denatured precursor IL-1beta exposing epitopes not exposed in the natural state. In immunoblots, depending on the number of cells, the antibody detects the 17000 MW band in supernatants as well as a 35000 MW band representing the 31000 MW IL-1beta precursor in lysates.
Anti-Human IL-1beta has been tested for use in neutralizations, ELISA, radioimmunoassays, flow cytometry, immunohistochemistry, immunoblotting and immunoprecipitation. It recognizes the 17000 MW mature IL-1beta. For immunoblots, typically, IL-1beta is detected from supernatants or lysates of 2 x 10E6 endotoxin-stimulated peripheral blood mononuclear cells (PBMC). PBMC are stimulated for 24 hours with 1% (v/v) serum plus 10 ng/mL E. coli LPS. For immunoprecipitation pre-clearing the preparation with a non-specific Rabbit IgG (p/n 011-001-297) to reduce background is suggested. For immunohistochemistry either paraffin fixation or cryofixation can be used for sample preparation to stain intracellular IL-1beta. For ELISA use HRP Conjugated Anti-Rabbit IgG [H&L] (Goat) (611-1302) for detection. In ELISA formats this antibody is best used as the second antibody in combination with a monoclonal antibody as a capture antibody. This antibody is also useful for neutralization of human and primate IL-1beta activity in bioassays. It does not neutralize the biological activity IL-1a. It does not neutralize the biological activity of murine, rat or rabbit IL-1beta. For neutralization, it is recommended to incubate the sample with a 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.

IL-1 Beta is a member of the interleukin 1 cytokine family. This cytokine is produced by activated macrophages as a proprotein, which is proteolytically processed to its active form by caspase 1 (CASP1/ICE). This cytokine is an important mediator of the inflammatory response, and is involved in a variety of cellular activities, including cell proliferation, differentiation, and apoptosis.
