This sandwich ELISA can detect both natural and recombinant human IL-5. This kit exhibits no detectable cross-reactivity with human; GM-CSF, GRO a, GRO b, INF-g, INF a, IL-1a, IL-1b, IL-1 RA, IL-2, IL-3, IL-4, IL-6, IL-7, IL-8, IL-9, IL-10, IL- 11, IL-12, IL-13, IL-15, TNF-a, mouse IL-5 and IL-9.
Serum, plasma, cell culture medium, and urine
Assay Type
The minimum detectable quantities of human IL-5 as observed by the standard curve generated for both Calibrator Diluent I and Calibrator Diluent II are 7.5 pg/mL and 6.3 pg/mL respectively. The two standard deviations above the mean optical density of the 20 replicates of the zero standard were defined as the minimum detectable quantities.
Intra-assay Precision
To determine within-run precision, three different samples of known concentration were assayed by replicates of 20 in 1 assay.
Inter-assay Precision
To determine between-run precision, three different samples of known concentration were assayed by replicates on 20 different assays.
Intended Uses
This Human Interleukin 5 ELISA Kit is to be used for the in vitro quantitative determination of human interleukin 5 (IL-5) concentrations in serum, plasma, cell culture medium, and urine. This kit is intended for LABORATORY RESEARCH ONLY and is not to be used for diagnostic or therapeutic purposes.
Product Note
Our ELISA Kit assays are dynamic research tools and sometimes they may be updated and improved. If the format of this assay is important to you then please request the current manual or contact our technical support team with a presales inquiry before placing an order. We will confirm the current details of the assay. We cannot guarantee the sample manual posted online is the most current manual.
Other Notes
Small volumes of IL-5 elisa kit vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS590010 is a ready-to-use microwell, strip-or-full plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Interleukin-5 (IL-5) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing IL-5. The ELISA analytical biochemical technique of the MBS590010 kit is based on IL-5 antibody-IL-5 antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect IL-5 antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, IL-5. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

Principle of the assay: This IL-5 enzyme linked immunosorbent assay (ELISA) applies a technique called a quantitative sandwich immunoassay. The microtiter plate provided in this kit has been pre-coated with a monoclonal antibody specific to IL-5. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated monoclonal antibody preparation specific for IL-5 and incubated. IL-5, if present, will bind and become immobilized by the antibody pre-coated on the wells and then become "sandwiched" by biotin conjugate. The microtiter plate wells are thoroughly washed to remove unbound IL-5 and other components of the sample. In order to quantitatively determine the amount of IL-5 present in the sample, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Avidin is a tetramer containing four identical subunits, each having a high affinity-binding site for biotin. The wells are thoroughly washed to remove all unbound HRP-conjugated Avidin and a TMB (3,3'5,5' tetramethyl-benzidine) substrate solution is added to each well. The enzyme (HRP) and substrate are allowed to react over a short incubation period. Only those wells that contain IL-5, biotin-conjugated antibody, and enzyme-conjugated Avidin will exhibit a change in colour. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the colour change is measured spectrophotometrically at a wavelength of 450 nm +/- 2 nm.

NCBI Summary for IL-5
This gene encodes a cytokine that acts as a growth and differentiation factor for both B cells and eosinophils. The encoded cytokine plays a major role in the regulation of eosinophil formation, maturation, recruitment and survival. The increased production of this cytokine may be related to pathogenesis of eosinophil-dependent inflammatory diseases. This cytokine functions by binding to its receptor, which is a heterodimer, whose beta subunit is shared with the receptors for interleukine 3 (IL3) and colony stimulating factor 2 (CSF2/GM-CSF). This gene is located on chromosome 5 within a cytokine gene cluster which includes interleukin 4 (IL4), interleukin 13 (IL13), and CSF2 . This gene, IL4, and IL13 may be regulated coordinately by long-range regulatory elements spread over 120 kilobases on chromosome 5q31. [provided by RefSeq, Jul 2013]
