Human IL-1 alpha/IL-1F1 ELISA Kit (Colorimetric) Summary
Description
This kit is an enzyme-linked immunosorbent assay for quantitative detection.
Specificity
The interference of circulating factors of the immune system was evaluated by spiking these proteins at physiologically relevant concentrations into a human IL-1 alpha positive serum. There was no crossreactivity detected.
Standard Curve Range
1.6 - 100 pg/mL
Sensitivity
1.1 pg/mL
Assay Type
Sandwich ELISA
Inter-Assay
CV% < 10%
Intra-Assay
CV% < 5.40%
Spike Recovery
The amount of endogenous human IL-1 alpha in unspiked samples was subtracted from the spike values. The overall mean recovery was 92%.

Background
The interleukin-1 species represent an important family of biologically active mono nuclear cell-derived proteins which are involved in inflammatory reactions and in immune responses. Two distinct human IL-1 species, IL-1alpha and IL-1beta, have been identified. They share similarities such as the same molecular weight, similar biological effects and the same receptors on target cells. IL-1 proteins are produced by macrophages, monocytes and various other cell types such as adult T cell leukemias, fibroblasts, epithelial or endothelial cells, neutrophils and astrocytes. Their biological properties include pyrogenicity, bone resorption, presentation of antigen to T cells and stimulation of B and T lymphocyte proliferation. IL-1alpha is an extracellular peptide of 17 kDa, its activity has been demonstrated in various biological fluids including serum, synovial fluid, gingival fluid, amniotic fluid, sputum, cerebrosinal fluid, urine, and bronchoalveolar lavage (BAL) fluid. Elevated serum or blood levels of IL-1alpha have been found in patients with total hip replacement/ arthroplasties, in patients with recently diagnosted IDDM (Insulin-Dependent Diabetes Mellitus), in case of several carcinomas such as head and neck cancer, pancreatic cancer and thyroid cancer, in experimental acute pyelonephritis, in acute viral hepatitis and in septic shock.
