Application: Optimal antibody pair and antigen standard for assaying Rat IL-1α/IL-1F1. Can be multiplexed with other analytes in Rat Group 1. To be used in conjunction with the AimPlex Mouse/Rat Basic Kit (PN: P200201) and a diluent kit. Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.

Storage:  2-8 C in the dark.

Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Interleukin 1 alpha (Accession P16598), also known as hematopoietin-1 is a member of the Interleukin 1 cytokine family. Originally thought to be just Interleukin-1, IL-1α is in fact a distinct protein from interleukin-1 β. It is a pro-inflammatory cytokine that especially incites fever and sepsis. IL-1α is primarily produced by macrophages, neutrophils, epithelial and endothelial cells. It binds to IL-1 receptor, which also binds to IL-1 receptor antagonist. IL-1α acts as a type of molecular “decision-making nexus” of cells over the severity of damage or infection to their associated tissue. It is also an important cytokine in barrier function of  the epidermis during the aging process.
