Human ES (Endostatin) CLIA Kit

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

This CLIA kit uses the Sandwich-CLIA principle. The micro CLIA plate provided in this kit has been pre-coated with an antibody specific to Human ES. Standards or samples are added to the micro CLIA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human ES 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 Human ES, biotinylated detection antibody and Avidin-HRP conjugate will appear fluorescence. The Relative light unit (RLU) value is measured by the Chemiluminescence immunoassay analyzer. The RLU value is positively associated with the concentration of Human ES. You can calculate the concentration of Human ES in the samples by comparing the RLU value of the samples to the standard curve.

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

As the RLU 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.

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

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

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

An unopened kit can be stored at 4℃ for 1 month. If the kit is not used within 1 month, store the items separately according to the following conditions once the kit is received.

Note: All reagent bottle caps must be tightened to prevent evaporation and microbial pollution.
The volume of reagents in partial shipments is a little more than the volume marked on the label, please use accurate measuring equipment instead of directly pouring into the vial(s).
