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

Matrix Recovery range (%) Average(%)
serum(n=5) 89-104 93
EDTA plasma(n=5) 91-98 94
heparin plasma(n=5) 84-102 90


Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Neurogranin (NRGN) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Neurogranin (NRGN) 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 Neurogranin (NRGN) 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) 85-103% 98-105% 91-105% 90-104%
EDTA plasma(n=5) 87-103% 95-103% 95-104% 86-97%
heparin plasma(n=5) 78-94% 82-99% 81-89% 80-103%


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.

ELISA Kit for Neurogranin (NRGN)

Test principle

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Neurogranin (NRGN) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Neurogranin (NRGN) and unlabeled Neurogranin (NRGN) (Standards or samples) with the pre-coated antibody specific to Neurogranin (NRGN). 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 Neurogranin (NRGN) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Neurogranin (NRGN) in the sample.
