Anti-Interleukin-1α antibody produced in goat

IgG fraction of antiserum, lyophilized powder

Synonym: Anti-IL-1α



recombinant mouse IL-1α.

General description

Interleukins are proinflammatory cytokines produced on cell injury or trauma. There are two closely related types of interleukins produced by the cell, IL-1α and IL-1β that are produced by the activation of NF-κ B transcription factor in response to bacterial infection or LPS. Both IL-1α and IL-1β exert their cellular effects by signalling through IL-1 receptor type 1. A variety of cells such as macrophages, epithelial cells, fibroblasts, keratinocytes, monocytes and dendritic cells secrete IL-1α. Both IL-1α and IL-1β are important in acquired immunity, inflammation, response to infection and production of matrix metalloproteinases (MMPs). The effects of IL-1α are mediated by activation of NF-κB, JNK and MAPK pathways that activated the genes in response to infection and inflammation. Overproduction of IL-1α has been implicated in inflammatory disorders like rheumatoid arthritis and periodontitis
Anti-interleukin-1α specifically reacts with mouse IL-1α. It does not react with human IL-1α and IL-1β or mouse IL-1β.

Physical form

Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline pH 7.4, with 5% trehalose.


The antibody will neutralize the biological activity of recombinant mouse IL-1α, but not recombinant human IL-1α, IL-1β or recombinant mouse IL-1β.


Anti-interleukin 1α antibody is suitable for neutralization reactions and the recommended ND50 is 0.04-0.2 μg/ml. The antibody may be used for immunoblotting at a working concentration of 1-2 μg/ml. It is also suitable for indirect ELISA applications.
