      Intended use

      This ELISA kit applies to the in vitro quantitative determination of Human Salusinα concentrations in serum, plasma and other biological fluids.

      Test principle

      This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Human Salusinα. During the reaction, Human Salusinα in the sample or standard competes with a fixed amount of Human Salusinα on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Human Salusinα. Excess conjugate and unbound sample or standard are washed from the plate, and Avidin conjugated to Horseradish Peroxidase (HRP) are added to each microplate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color change is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of Human Salusinα in the samples is then determined by comparing the OD of the samples to the standard curve.

      Specificity

      This kit recognizes Human Salusinα in samples. No significant cross-reactivity or interference between Human Salusinα and analogues was observed.

      Typical data

      As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.

      Precision

      Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Human Salusinα were tested 20 times on one plate, respectively.
      Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Human Salusinα were tested on 3 different plates, 20 replicates in each plate.

      Recovery

      The recovery of Human Salusinα spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

      Sample Type Range (%) Average Recovery (%)
      Serum (n=5) 89-104 97
      EDTA plasma (n=5) 92-104 98
      Cell culture media (n=5) 90-100 95

      Linearity

      Samples were spiked with high concentrations of Human Salusinα and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
