• Reactivity: Human
• Specificity: This assay has high sensitivity and excellent specificity for detection of High Sensitive Interleukin 2 (IL2).; No significant cross-reactivity or interference between High Sensitive Interleukin 2 (IL2) and analogues was observed.
• Sequence Length: 153

• Applicable Applications for IL2 elisa kit: ELISA (EIA)
• Assay Type: Double-antibody Sandwich
• Samples: Serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids
• Detection Range: 1.56-100pg/mL
• Sensitivity: The minimum detectable dose of this kit is typically less than 0.64pg/mL
• Precision: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level High Sensitive Interleukin 2 (IL2) were tested 20 times on one plate, respectively.; Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level High Sensitive Interleukin 2 (IL2) were tested on 3 different plates, 8 replicates in each plate.; CV(%) = SD/meanX100; Intra-Assay: CV<10%; Inter-Assay: CV<12%
• Test Principle: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to High Sensitive Interleukin 2 (IL2). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to High Sensitive Interleukin 2 (IL2). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain High Sensitive Interleukin 2 (IL2), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of High Sensitive Interleukin 2 (IL2) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
• Preparation and Storage: The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.; To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

NCBI Description

The protein encoded by this gene is a secreted cytokine that is important for the proliferation of T and B lymphocytes. The receptor of this cytokine is a heterotrimeric protein complex whose gamma chain is also shared by interleukin 4 (IL4) and interleukin 7 (IL7). The expression of this gene in mature thymocytes is monoallelic, which represents an unusual regulatory mode for controlling the precise expression of a single gene. The targeted disruption of a similar gene in mice leads to ulcerative colitis-like disease, which suggests an essential role of this gene in the immune response to antigenic stimuli.

Uniprot Description

IL2: Produced by T-cells in response to antigenic or mitogenic stimulation, this protein is required for T-cell proliferation and other activities crucial to regulation of the immune response. Can stimulate B-cells, monocytes, lymphokine- activated killer cells, natural killer cells, and glioma cells. A chromosomal aberration involving IL2 is found in a form of T-cell acute lymphoblastic leukemia (T-ALL). Translocation t(4;16)(q26;p13) with involves TNFRSF17. Belongs to the IL-2 family.
