ELISA Kit for Osteoglycin (OGN)


This test has high sensitivity and excellent specificity for the detection of osteoglycin (OGN).
No cross-reactivity or significant interference between osteoglycin (OGN) and the analogues was observed.


Intra-assay precision (precision within an assay): 3 samples with low, medium and high osteoglycin (OGN) levels were tested 20 times on a plate, respectively.
Inter-assay precision (precision between assays): 3 samples with low, medium and high osteoglycine (OGN) levels were tested on 3 different plates, 8 replicates in each plate.
CV (%) = SD / meanX100
Intra-assay: CV <10%
Inter-assay: CV <12%


The stability of the kit is determined by the rate of activity loss. The wastage rate of this kit is less than 5% by the expiration date under proper storage conditions.
To minimize the further influence on performance, operating procedures and laboratory conditions, especially room temperature, air humidity and incubator temperature, should be strictly controlled. It is also strongly suggested that the whole test be performed by the same operator from start to finish.
