Sample type Serum, plasma, tissue homogenates and other biological fluids Detection range 13.717-10000pg/mL The standard curve concentrations used for the ELISA's were 10000pg/mL, 3333.33pg/mL, 1111.11pg/mL, 370.37pg/mL, 123.457pg/mL, 41.152pg/mL, 13.717pg/mL
Sensitivity The minimum detectable dose of this kit is typically less than 6.03pg/mL. Specificity This assay has high sensitivity and excellent specificity for detection of Nitric Oxide Synthase 1, Neuronal (NOS1).
No significant cross-reactivity or interference between Nitric Oxide Synthase 1, Neuronal (NOS1) and analogues was observed.

Recovery Matrices listed below were spiked with certain level of recombinant Nitric Oxide Synthase 1, Neuronal (NOS1) and the recovery rates were calculated by comparing the measured value to the expected amount of Nitric Oxide Synthase 1, Neuronal (NOS1) in samples.
Matrix Recovery range (%) Average(%)
EDTA plasma(n=5)95-10399
heparin plasma(n=5)93-10197

Precision Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Nitric Oxide Synthase 1, Neuronal (NOS1) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Nitric Oxide Synthase 1, Neuronal (NOS1) 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 Nitric Oxide Synthase 1, Neuronal (NOS1) 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

heparin plasma(n=5)90-104%81-104%88-102%80-97%

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.
Test principle The microtiter plate provided in this kit has been pre-coated with an antigen. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated secondary antibody. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. 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 proportional to the Nitric Oxide Synthase 1, Neuronal (NOS1) level in the sample or standard. Assay procedure summary 1.
