IL-1 alpha Protein (SIL1A) in ELISA Std
Sandwich ELISA analysis of human IL-1 alpha was performed using a Human IL-1 alpha Colorimetric ELISA Kit (Product # EH2IL1A) by loading 50ul per well of Human IL-1 alpha Recombinant Protein (Product # SIL1A) in dodecuplicate at 400, 160, 64, 25.6, 10.25 and 0 pg/ml across a 3ug/ml mouse anti-human IL-1 alpha (Product # M421A) pre-coated plate and incubating for 1 hour at room temperature. The plate was washed, then incubated with 50ul per well of a biotinylated-mouse anti-human IL-1 alpha (Product # M420AB) in dodecuplicate at 0.15µg/ml ... View More

Product Specific Information
The human IL-1a standard is calibrated against WHO IL-1a Reference Standard lot (8)6/632. 1 Thermo pg = 1 WHO pg = 0.1 WHO units.
Lyophilized product is shipped on cold packs. Stable until expiration if stored desiccated at 2-8°C. Reconstituted cytokine standards should be stored in aliquots at -70°C. Each aliquot should be used only once and discarded afterwards. Stability of reconstituted and frozen cytokine standards may vary. Controls should be run with each standard curve.
Sufficient For: ELISA standard curve with replicates or as a control in Western blots.
1000 pg/ml when reconstituted at the recommend volume.
Reconstitute with distilled water at volume indicated on label. Use or freeze product within 1 hour of reconstitution.
Target Information
IL-1 alpha (Interleukin-1 alpha) is a proinflammatory cytokine expressed by monocytes, macrophages, and dendritic cells. IL-1 alpha is coded by the IL1A gene and signals through two receptors, IL-1RI and IL-1RII, both of which are shared with IL-1 beta. IL1A is located on the q arm on chromosome 2 at position 13. IL-1 alpha plays an important role in innate host defense by triggering the production of other proinflammatory cytokines in target cells and initiating acute-phase responses. IL-1 alpha activity can be moderated by IL-1 Receptor Antagonist (IL-1RA), a protein produced by many cell types that blocks receptor binding through competitive inhibition. IL-1 alpha is a pleiotropic cytokine involved in various immune responses, inflammatory processes, and hematopoiesis. Further, IL-1 alpha is produced by monocytes and macrophages as a proprotein, which is proteolytically processed and released in response to cell injury and induces apoptosis. The IL1A gene and eight other interleukin 1 family genes form a cytokine gene cluster on chromosome 2. IL1 alpha regulates the activities of NF-kappaB and mitogen-activated protein kinases. IL-1 alpha can stimulate the expression of IL6 and cyclooxygenase-2 (PTGS2/COX-2), as well as enhance the production of nitric oxide (NO). High levels of IL-1 alpha are associated with several chronic inflammatory diseases including rheumatoid arthritis, psoriasis and multiple sclerosis.
