Performance

Typical data

The following data was generated by the Quality Control Department, under controlled laboratory conditions (ambient temperature: 18-25 °C, relative humidity: 35-75%) using standardized procedures (TMB reaction at 37 °C in the dark for 15 minutes, followed by termination and OD measurement). These values are provided for reference only. Actual results may vary due to differences in laboratory conditions, operator technique, and equipment. Users are required to generate a standard curve using their own experimental data.

Precision

Intra-assay Precision (Within-run Precision): Three samples representing low, mid, and high concentrations of Human IL-6 were tested 20 times on a single plate.

Inter-assay Precision (Between-run Precision): Three samples representing low, mid, and high concentrations of Human IL-6 were tested on three separate plates, with 20 replicates per plate, to assess variability among assays.

Recovery

The recovery of Mouse IgE was evaluated by spiking samples at low, mid, and high concentrations across the assay range in various sample matrices.
The assay performance was assessed by comparing the measured concentrations to the expected spiked amounts to determine the percent recovery.

Sample Type	Range （%）	Average Recovery（%）
Serum （n=8）	90-100	95
EDTA plasma （n=8）	88-103	95
Cell culture media （n=8）	90-104	97

Linearity

Linearity of the assay was evaluated by spiking samples with high concentrations of Mouse IgE and performing serial dilutions using Standard & Sample Diluent to produce concentrations spanning the assay's dynamic range. The measured values were then compared to the expected concentrations to assess the linearity of response.

1:8	Average	95	100	90

Stability

Each kit batch is subjected to accelerated stability testing and real-time stability monitoring. Sample performance is evaluated after storage at 37 °C for 10 days to assess the impact of elevated temperature on assay reliability and reagent integrity.

/	Variation range of 37°C mean concentration / 2-8°C mean
Sample 1（n=16）	85.40-111.68
Sample 2（n=16）	105.88-109.70

Test Principle

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to IgE . Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for IgE and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain IgE , biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of IgE . You can calculate the concentration of IgE in the samples by comparing the OD of the samples to the standard curve.

Background

IgE, Immunoglobulin E (Ige), is a kind of immune globulin, mainly involved in allergic reactions and parasitic infections and other immune reactions. IgE can produce allergic reactions, such as asthma and allergic rhinitis, when the body is exposed to certain antigens. Measurement of IgE levels can help diagnose and monitor the extent of these allergic reactions and the efficacy of treatment.
