The kit is a competitive inhibition enzyme immunoassay technique for the in vitro quantitative measurement of PLS3 in human serum, plasma, tissue homogenates or other biological fluids.
 
DETECTION RANGE
0.625-40ng/mL. The standard curve concentrations used for the ELISA’s were 40ng/mL, 20ng/mL, 10ng/mL, 5ng/mL, 2.5ng/mL, 1.25ng/mL, 0.625ng/mL.
 
 SENSITIVITY
The minimum detectable dose of PLS3 is typically less than 0.299ng/mL.
The sensitivity of this assay, or Lower Limit of Detection (LLD) was defined as the lowest protein concentration that could be differentiated from zero. It was determined by adding two standard deviations to the mean optical density value of twenty zero standard replicates and calculating the corresponding concentration.
 
 SPECIFICITY
This assay has high sensitivity and excellent specificity for detection of PLS3.
No significant cross-reactivity or interference between PLS3 and analogues was observed.

Test principle

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to the index has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled the index and unlabeled the index (Standards or samples) with the pre-coated antibody specific to the index. After incubation the unbound conjugate is washed off. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of the index in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of the index in the sample.

Recovery

Matrices listed below were spiked with certain level of recombinant PLS3 and the recovery rates were calculated by comparing the measured value to the expected amount of the index in samples.

Matrix Recovery range (%) Average(%)
serum(n=5) 81-93 86
EDTA plasma(n=5) 80-97 88
heparin plasma(n=5) 90-101 95

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of the index 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) 82-96% 83-98% 81-99% 93-101%
EDTA plasma(n=5) 88-101% 86-95% 90-102% 80-93%
heparin plasma(n=5) 80-91% 82-90% 95-104% 79-95%

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level the index were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level the index were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%
 

Stability

The stability of ELISA 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.
Note:
To minimize unnecessary influences on the performance, operation procedures and lab conditions, especially room temperature, air humidity, and incubator temperatures should be strictly regulated. It is also strongly suggested that the whole assay is performed by the same experimenter from the beginning to the end.
