The Canine Thyroid Stimulating Hormone (TSH) ELISA Kit is specifically designed for the quantitative detection of TSH levels in canine serum, plasma, and cell culture supernatants. This highly sensitive and specific kit delivers reliable and reproducible results, making it an invaluable tool for a variety of research applications.TSH plays a key role in regulating thyroid function in dogs, making it an important biomarker for studying thyroid health and related conditions.
By accurately measuring TSH levels, researchers can gain valuable insights into thyroid function and potential disorders, ultimately leading to advancements in veterinary medicine and improved care for canine patients.
Matrices listed below were spiked with certain level of recombinant the index and the recovery rates were calculated by comparing the measured value to the expected amount of the index in samples.

Linearity:
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of the index and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Intra-assay Precision:
Intra-Assay: CV <10%. 3 samples with low, middle and high level the index were tested 20 times on one plate, respectively.
Inter-assay Precision:
Inter-Assay: CV <12%. 3 samples with low, middle and high level the index were tested on 3 different plates, 8 replicates in each plate.
Stability:
The stability of ELISA 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. Note:To minimize unnecessary influences on the performance, operation procedures and lab conditions, especially room temperature, air humidity, and incubator temperatures should be strictly regulated. It is also strongly suggested that the whole assay is performed by the same experimenter from the beginning to the end.
