Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Human sIgA were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Human sIgA were tested on 3 different plates, 20 replicates in each plate.
|Intra-assay Precision||Inter-assay Precision|
The recovery of Human sIgA spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.
|Sample Type||Range (%)||Average Recovery (%)|
|EDTA plasma (n=8)||93-108||100|
|Cell culture media (n=8)||84-98||90|
Samples were spiked with high concentrations of Human sIgA and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
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
