Immunohistochemistry: we recommend use of 1 μg per ml as a starting dilution. Paraffin sections may require pretreatment like Proteinase K or Trypsin predigestion toimprove staining. Neutralization: To yield one-half maximal inhibition [ND50] of the biological activity of rIL-1alpha (50 pg/mL), a concentration of 0.011-0.017 μg/mL of this antibody is required. ELISA: To detect rIL-1 alpha by direct ELISA (using 100 ml/well antibody solution) aconcentration of at least 0.5 μg/mL of this antibody is required. This antigen affinitypurified antibody, in conjunction with compatible secondary reagents, allows the detectionof 0.2-0.4 ng/well of recombinant rIL-1 alpha. Western blot: To detect rIL-1 alpha by Western Blot analysis this antibody can be used at aconcentration of 0.1-0.2 μg/mL. Used in conjunction with compatible secondary reagentsthe detection limit for recombinant rIL-1 alpha is 1.5-3.0 ng/lane, under either reducing ornon-reducing conditions. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

Interleukins (ILs) are a large group of cytokines that are produced mainly by leukocytes, although some are produced by certain phagocytes and auxiliary cells. Each IL acts on a specific, limited group of cells through a receptor specific for that IL. Interleukin 1 (IL1), originally known as lymphocyte activating factor (LAF), activates T cells and lymphocytes, which then proliferate and secrete interleukin 2. IL1 is primarily released from stimulated macrophages and monocytes, but also is released from several other cell types and is thought to play a key role in inflammatory and immune responses. The two closely related agents, interleukin 1 alpha (IL1 alpha) and interleukin 1 beta (IL1 beta) bind to the same cell surface receptor, elicit nearly identical biological responses and share 25 % homology in their amino acid sequence.Synonyms: Hematopoietin-1, IL-1 alpha, IL1A, IL1F1
