ELISA Kit for Family With Sequence Similarity 19, Member A5 (FAM19A5)

TAFA-5; Chemokine-like protein TAFA-5

Specificity

This assay has high sensitivity and excellent specificity for detection of Family With Sequence Similarity 19, Member A5 (FAM19A5).
No significant cross-reactivity or interference between Family With Sequence Similarity 19, Member A5 (FAM19A5) and analogues was observed.

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Family With Sequence Similarity 19, Member A5 (FAM19A5) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Family With Sequence Similarity 19, Member A5 (FAM19A5) 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 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.
