Application This ELISA kit applies to the in vitro quantitative determination of Human AChR-Ab concentrations in Serum, plasma and other biological fluids.

 

 Test Principle

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 Human AChR-Ab. Samples (or
Standards) are added to the micro ELISA plate wells and combined with the antigen. Then a biotinylated detection antigen specific for Human AChR-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 Human AChR-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±2 nm. The OD value is proportional to the concentration of Human AChR-Ab. You can calculate the
concentration of Human AChR-Ab in the samples by comparing the OD of the samples
to the standard curve.

Technical Data:

Precision

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

 Recovery

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

EDTA plasma (n=8) 90-104 95

 

 Assay Procedures

1. Add 100μL standard or sample to the wells. Incubate for 90 min at 37°C

2. Discard the liquid, immediately add 100μL Biotinylated Detection Ab working solution to each well. Incubate for 60 min at 37°C

3. Aspirate and wash the plate for 3 times

4. Add 100μL HRP conjugate working solution. Incubate for 30 min at 37°C. Aspirate and wash the plate for 5 times

5. Add 90μL Substrate Reagent. Incubate for 15 min at 37°C

6. Add 50μL Stop Solution

7. Read the plate at 450nm immediately. Calculation of the results
