Sandwich ELISA analysis of human IL-1b was performed using a Human IL-1b Colorimetric ELISA Kit (Product # EH2IL1B) by loading 50 ul per well of Human IL-1b Recombinant Protein (Product # SIL1B) in quadruplicate at 400, 160, 64, 25.6, 10.24 and 0 pg/ml across a 5 ug/ml mouse anti-human IL-1b (Product # M421B) pre-coated plate and incubating for 3 hours at room temperature. The plate was washed then incubated with 50 ul per well of a biotinylated-mouse anti-human IL-1b monoclonal antibody (Product # M420BB) in quadruplicate at 0.07 ug/ml for 3 hours at room temperature. The plate was washed and incubated with 100 ul per well of Ultra Streptavidin-HRP (Product # N504) in all test wells at 1:3000 for 30 minutes at room temperature. Detection was performed using Ultra TMB Substrate (Product # 34028) for 30 minutes at room temperature in the dark. The plate was then stopped with 0.16M sulfuric acid. Absorbances were read on a spectrophotometer at 450-550 nm.

The human IL-1beta Standard is calibrated against WHO IL-1beta Reference Standard lot #86/522. 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.
For Research Use Only. Not for use in diagnostic procedures. Not for resale without express authorization.
