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

Matrix Recovery range (%) Average(%)
serum(n=5) 78-95 92
EDTA plasma(n=5) 78-91 82
heparin plasma(n=5) 98-105 102


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


The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Galanin (GAL) 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) 79-94% 93-105% 87-101% 81-104%
EDTA plasma(n=5) 79-90% 87-94% 89-97% 78-98%
heparin plasma(n=5) 96-104% 84-105% 92-105% 80-94%


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.

CLIA Kit for Galanin (GAL)

Test principle

The microplate provided in this kit has been pre-coated with a monoclonal antibody specific to Galanin (GAL). A competitive inhibition reaction is launched between biotin labeled Galanin (GAL) and unlabeled Galanin (GAL) (Standards or samples) with the pre-coated antibody specific to Galanin (GAL). 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 Galanin (GAL) in the sample. Then the mixture of substrate A and B is added to generate glow light emission kinetics. Upon plate development, the intensity of the emitted light is reverse proportional to the Galanin (GAL) level in the sample or standard.
