Human Dimethylarginine Dimethylaminohydrolase 1 (DDAH1) ELISA Kit
The Human Dimethylarginine Dimethylaminohydrolase 1 (DDAH1) ELISA Kit is specifically designed for the accurate and reliable detection of DDAH1 levels in human serum, plasma, and cell culture supernatants. Our kit offers high sensitivity and specificity, ensuring precise and reproducible results for a variety of research applications.DDAH1 is an important enzyme involved in the metabolism of nitric oxide (NO) within the body. Dysregulation of DDAH1 has been linked to various diseases, including cardiovascular disorders, kidney disease, and neurodegenerative conditions.
By measuring DDAH1 levels, researchers can gain valuable insights into these pathways and potentially develop new therapeutic strategies.This ELISA kit is user-friendly and provides everything needed for efficient and accurate detection of DDAH1 levels. Trust in the reliability and performance of our Human DDAH1 ELISA Kit for your research needs.

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 conditions. 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.
