Microplate kits and reagent sets for sandwich ELISA of human interleukin-2 (IL-2).
Assay IL-2 (human interleukin-2) levels in human serum, plasma (EDTA, heparin, sodium citrate), urine and culture supernatant samples with our Thermo Scientific Human IL-2 ELISA Kits.
These human IL-2 ELISA kits use pre-titered, matched pairs of coating and detection antibodies to achieve sensitive and accurate measurement of interleukin-2 (IL-2) in samples at 50 to 100μL per well. Also included are calibrated recombinant protein standard, streptavidin-HRP, TMB substrate solution and stop solution. The complete kits contain pre-coated 96-well strip plate(s) and lot-optimized reagents. The economically-priced reagent kit provides validated reagents only, requiring users to coat their own plates. The antibody-pair kit consists of the matched IL-2 antibody pairs and IL-2 standard only. All components undergo quality control testing to minimize lot-to-lot variability.
Highlights: †
Target: natural and recombinant human interleukin-2 (IL-2)
Format: colorimetric ELISA (TMB substrate) in clear 96-well strip plate
Measurement: absorbance at 450nm minus absorbance at 550nm
Specificity: no significant cross-reaction with human IL-1α, IL-1β, IL-3, IL-4, IL-6, IL-7, IL-8, TNFα, TNFβ, GM-CSF, INFγ, or mouse IL-2.
†Note: Assay range and other values listed above are for the pre-coated plate kit; see product documentation for values specific to the reagent kit and antibody-pair kit.
Includes:
Complete Kits contain pre-coated antibody-plates, detection antibodies, buffers, diluents, standards, and substrates. The Reagent Kit (previously called a "Screening Set") contains matched antibodies, standard and detection reagents but no coated plates. The Antibody Pair Kit (previously called a "MiniKit") contains only matched antibodies and standard (no plates or detection reagents).
Human IL-2 ELISA standard curve. An example standard curve for the Thermo Scientific Human IL-2 ELISA Kit (Part No. EH2IL2), with error bars based on five replicates for each interleukin-2 standard concentration. Also see standard curves for the IL-2 Reagent Kit and IL-2 Antibody Pair Kit.
