Human 7-Dehydrocholesterol Reductase (DHCR7) ELISA Kit
The Human 7-Dehydrocholesterol Reductase (DHCR7) ELISA Kit is specifically designed to accurately detect levels of DHCR7 in human serum, plasma, and cell culture supernatants. This kit offers high sensitivity and specificity, ensuring reliable and reproducible results for a variety of research applications.DHCR7 is an important enzyme involved in the cholesterol biosynthesis pathway, specifically in the conversion of 7-dehydrocholesterol to cholesterol. Mutations in the DHCR7 gene can lead to the genetic disorder Smith-Lemli-Opitz syndrome, impacting cholesterol metabolism and causing a range of developmental and cognitive impairments.
By measuring DHCR7 levels, researchers can gain insights into cholesterol metabolism and its role in various physiological and pathological conditions. The Human DHCR7 ELISA Kit provides a valuable tool for studying cholesterol homeostasis, metabolic disorders, and potential therapeutic interventions.

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.
