Recovery
Matrices listed below were spiked with certain level of Sphingosine-1-Phosphate (S1P) ,etc. by CBA (Cytometric Bead Array) and the recovery rates were calculated by comparing the measured value to the expected amount of Sphingosine-1-Phosphate (S1P) ,etc. by CBA (Cytometric Bead Array) in samples.
| Matrix | Recovery range (%) | Average(%) |
| serum(n=5) | 82-102 | 90 |
| EDTA plasma(n=5) | 89-96 | 92 |
| heparin plasma(n=5) | 79-97 | 82 |
Precision
Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Sphingosine-1-Phosphate (S1P) ,etc. by CBA (Cytometric Bead Array) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Sphingosine-1-Phosphate (S1P) ,etc. by CBA (Cytometric Bead Array) were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%
Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Sphingosine-1-Phosphate (S1P) ,etc. by CBA (Cytometric Bead Array) and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
| Sample | 1:2 | 1:4 | 1:8 | 1:16 |
| serum(n=5) | 84-94% | 97-105% | 87-95% | 96-103% |
| EDTA plasma(n=5) | 80-101% | 91-103% | 96-104% | 90-99% |
| heparin plasma(n=5) | 95-103% | 87-95% | 93-103% | 96-105% |
Stability
The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.
To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Assay procedure summary
1. Add 200μL analysis buffer solution to each well of the plate for pre-wetting;
2. Preparation of standards, reagents and samples before the experiment;
3. Add 50μL standard or sample to each well, add 50μL prepared Detection Reagent A, add 10μL magnetic beads, and incubate 90 minutes protect from light at 25°C on shaker;
4. Remove liquid on magnetic frame, add 100μL prepared Detection Reagent B, and incubate 30 minutes protect from light at 25°C on shaker;
5. Wash plate once on magnetic frame;
6. Add 100μL sheath fluid, swirl for 10 minutes, read on the machine.
Test principle
Anti-Sphingosine-1-Phosphate (S1P) ,etc. by CBA (Cytometric Bead Array) antibody was coated on the surface of magnetic beads. A competitive inhibition reaction is launched between biotin labeled Sphingosine-1-Phosphate (S1P) ,etc. by CBA (Cytometric Bead Array) and unlabeled Sphingosine-1-Phosphate (S1P) ,etc. by CBA (Cytometric Bead Array) (Standards or samples) with the pre-coated antibody specific to Sphingosine-1-Phosphate (S1P) ,etc. by CBA (Cytometric Bead Array). PE-labeled avidin was added. The amount of bound PE conjugate is reverse proportional to the concentration of Sphingosine-1-Phosphate (S1P) ,etc. by CBA (Cytometric Bead Array) in the sample, the intensity of MFI developed is reverse proportional to the concentration of Sphingosine-1-Phosphate (S1P) ,etc. by CBA (Cytometric Bead Array) in the sample.
