Technical Data
Precision
Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level ST/5-HT were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level ST/5-HT were tested on 3 different plates, 20 replicates in each plate.

Recovery
The recovery of ST/5-HT spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.
| Sample Type | Range (%) | Average Recovery (%) |
|---|---|---|
| Serum(n=8) | 95-107 | 100 |
| EDTA plasma(n=8) | 86-99 | 92 |
| Cell culture media(n=8) | 91-105 | 98 |
Linearity
Samples were spiked with high concentrations of ST/5-HT and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.

Assay Procedures
 |
1. Add 50μL standard or sample to the wells, immediately add 50μL Biotinylated Detection Ab working solution to each well. Incubate for 45 min at 37°C |
 |
2. Aspirate and wash the plate for 3 times |
 |
3. Add 100μL HRP conjugate working solution. Incubate for 30 min at 37°C. Aspirate and wash the plate for 5 times |
 |
4. Add 90μL Substrate Reagent. Incubate for 15 min at 37°C |
 |
5. Add 50μL Stop Solution |
 |
6. Read the plate at 450nm immediately. Calculation of the results |
