Human Secreted Frizzled Related Protein 1 (SFRP1) ELISA Kit
The Human Secreted Frizzled-Related Protein 1 (SFRP1) ELISA Kit is designed for the accurate detection of SFRP1 levels 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.SFRP1 is a key player in the Wnt signaling pathway and is involved in regulating cell proliferation, differentiation, and tissue homeostasis. Dysregulation of SFRP1 expression has been linked to various diseases, including cancer, fibrosis, and neurodegenerative disorders, making it a valuable biomarker for studying these conditions and developing potential therapeutic interventions.
Overall, the Human SFRP1 ELISA Kit provides researchers with a powerful tool to accurately measure SFRP1 levels, advancing our understanding of its role in disease pathogenesis and potentially leading to the development of novel treatment strategies.

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.
