Handling Instruction
|
The activity loss rate (stability) of this kit is less than 5% within the expiration date under appropriate storage conditions. To minimize extra influence on the stability, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. When not in use, kit components should be refrigerated. All reagents should be brought to room temperature before use. It is recommended that all standards, controls, and samples be run in duplicate. Do not mix or interchange different reagent lots from various kit lots.

Test Principle
|
The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Lipophilin B, Prostatein Like (LIPB). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Lipophilin B, Prostatein Like (LIPB). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Lipophilin B, Prostatein Like (LIPB), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Lipophilin B, Prostatein Like (LIPB) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Lipophilin B, Prostatein Like (LIPB) 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) | 90-102% | 78-102% | 84-92% | 94-105% |
| EDTA plasma(n=5) | 78-103% | 85-96% | 89-104% | 82-89% |
| heparin plasma(n=5) | 85-103% | 94-102% | 96-104% | 81-103% |
Matrices listed below were spiked with certain level of recombinant Lipophilin B, Prostatein Like (LIPB) and the recovery rates were calculated by comparing the measured value to the expected amount of Lipophilin B, Prostatein Like (LIPB) in samples.
| Matrix | Recovery range (%) | Average(%) |
| serum(n=5) | 95-102 | 98 |
| EDTA plasma(n=5) | 80-89 | 82 |
| heparin plasma(n=5) | 78-95 | 88 |
