Product details:
Human IL-1a ELISA Kit ab178008 is a rapid single-wash 90-min Sandwich ELISA to measure Human IL-1a in cell culture supernatant, citrate plasma, EDTA plasma, heparin plasma, serum. This SimpleStep sensitivity is 0.82 pg/mL.
How the assay works
Human IL-1a SimpleStep ELISA
employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA
plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA
protocol summary in the image section for further details.
Assay Specificity
Our SimpleStep ELISA
kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

Interleukin 1 (IL-1) refers to two proteins encoded by two different genes (IL-1a and IL-1b), both of which share the same cell surface receptors. IL-1a is a proinflammatory cytokine typically expressed under normal conditions in skin keratinocytes, some epithelial cells as well as some cells in the central nervous system. Under pathological conditions, IL-1a is also strongly expressed by monocytes, tissue macrophages, dendritic cells, B lymphocytes and NK cells. IL-1a is synthesized as a 31kDa precursor, some of which is cleaved prior to secretion into a 17.5kDa protein. IL-1a is biologically active both in a paracrine or systemic mode of action. The paracrine effects are mediated by the uncleaved portion of IL-1a, which is transported to the cell surface where it activates the IL-1 receptor type I (IL-1RI) of adjacent cells. The systemic effect is mediated by cleaved IL-1a, which is secreted into the bloodstream.
Signaling of IL-1 via its receptor, results in recruitment of the IL-1 R accessory protein (IL-1RAcP). This leads to a series of phosphorylation and ubiquitination events that ultimately activate the nuclear factor kB (NF-kB) and signal via the c-Jun N-terminal kinase (JNK) and the p38 mitogen-activated protein kinase (MAPK) pathways. These signaling events generate local and systemic responses that mediate acute phase inflammation, a critical host response to injury and infection. Under these circumstances, IL-1 induces fever, pain sensitivity, vasodilation, hypotention and slow wave sleep. All these responses are essential processes geared towards the re-establishment of tissue homeostasis. However, prolonged and inappropriate IL-1 induction has been shown to be associated with sepsis, rheumatoid arthritis, inflammatory bowel disease, acute and chronic myelogenous leukemia, insulin-dependent diabetes mellitus and atherosclerosis.
