Human IL-1 alpha / IL-1F1 Protein, His Tag (MALS verified)

  • Synonym
    IL1A,IL-1 ALPHA,IL1F1,IL1α
  • Source
    Human IL-1 alpha, His Tag (ILA-H5216) is expressed from human 293 cells (HEK293). It contains AA Ser 113 - Ala 271 (Accession # P01583-1).
    Predicted N-terminus: Ser 113
  • Molecular Characterization
    Online(Ser 113 - Ala 271) P01583-1

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 19.9 kDa. The protein migrates as 25-27 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by reduced SDS-PAGE.

    >90% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

    Contact us for customized product form or formulation.

  • Background
    Interleukin-1 alpha (IL1a) is also known as IL-1A, IL1, IL1-ALPHA,IL1F1,and is a cytokine of the interleukin-1 family. IL1a possesses a wide spectrum of metabolic, physiological, haematopoietic activities, and plays one of the central roles in the regulation of the immune responses. It binds to the interleukin-1 receptor. IL-1α is constitutively produced by epithelial cells. It is found in substantial amounts in normal human epidermis and is distributed in a 1:1 ratio between living epidermal cells and stratum corneum.The constitutive production of large amounts of IL-1α precursor by healthy epidermal keratinocytes interfere with the important role of IL-1α in immune responses, assuming skin as a barrier, which prevents the entry of pathogenic microorganisms into the body. In vitro, IL-1α possesses biological effect on cells in the picomolar to femtomolar range. In vivo, Shortly after an onset of an infection into organism, IL-1α activates a set of immune system response processes.
