Rat HPF4-Ab(Anti-Heparin/Platelet Factor 4) ELISA Kit

This ELISA kit applies to the in vitro quantitative determination of Rat HPF4-Ab concentrations in serum, plasma and other biological fluids.

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antigen specific to Rat HPF4-Ab. Standards or samples are added to the micro ELISA plate wells and combined with the specific antigen. Then a biotinylated detection antigen specific for Rat HPF4-Ab 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 Rat HPF4-Ab, biotinylated detection antigen 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 Rat HPF4-Ab. You can calculate the concentration of Rat HPF4-Ab in the samples by comparing the OD of the samples to the standard curve.

This kit recognizes Rat HPF4-Ab in samples. No Significant cross-reactivity or interference between Rat HPF4-Ab and analogues was observed.

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.

Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Rat HPF4-Ab were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Rat HPF4-Ab were tested on 3 different plates, 20 replicates in each plate.

The recovery of Rat HPF4-Ab spiked at two different levels in samples throughout the range of the assay was evaluated in various matrices.

Samples were spiked with high concentrations of Rat HPF4-Ab 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).
