Human Poliomyelitis Virus IgG,PV-IgG ELISA Kit, 96T

Purpose

This kit is used for the determination the existence of Human Poliomyelitis Virus IgG (PV-IgG) in human serum, plasma, cell culture supernatants, and other biological fluids.

 Principle of the assay

The kit assays human PV-IgG in the samples by the method of purified antigen pre-coated enzyme-labeled SPA ELISA. The solid-phase antigen is prepared by purified human antigen which is pre-coated onto a microplate. After loading of samples, the PV-IgG in the controls or samples bind with the coated antigen. Then the Staphylococcal protein A (SPA)-enzyme immunoglobulin conjugates has been added into wells. After washing to remove any unbound reagent, the tetramethylbenzidine (TMB) substrate is added. TMB substrate produces blue color when catalyzing by the HRP enzyme. After reaching the desired color intensity, the reaction is terminated by addition of an acidic Stop solution which changes the solution color from blue to yellow. Determining the absorbance (OD Value) at wave length 450 nm by the microwell reader, and the existence of PV-IgG can be calculated according to OD from positive or negative controls.

Calculation

1.       Average the duplicate readings for each control and sample and subtract the average of blank well (1 x sample buffer only).

2.       Determine P/N value: P/N= ODsample / ODnegative. If ODnegative is less than 0.1, please use 0.1 as the value. ODpositive or ODnegative is the OD from positive or negative control.

3.       If P/N ≥ 2.1, the testing sample is PV-IgG positive; if P/N< 2.1, the testing sample is PV-IgG negative.

4.       The normal range of ODnegative should be less than 0.21, and ODpositive should be more than 0.40, otherwise the experiment may have some issues and maybe need repeating.

5.       If the ODsample is less than 0.21, but the color of the well can be observed by eyes as blue, the sample is suspective and need to be tested again.

6.       If the ODsample is more than 2.5 or less than 0.1, it is out of the optimal test range. Dilution or concentration of sample may be necessary for accuracy.

Kit Performance

1.    Sample from healthy people should be negative, e.g. P/N < 2.1.

2.  Specificity: simultaneous detection of recombinant or natural human PV-IgG without cross-reaction with other cytokines.

3.   Repeatability: both inter-assay and intra-assay were less than 10 %.
