Human Left/Right Determination Factor 1 (LEFTY1) ELISA Kit
The Human Left-Right Determination Factor 1 (LEFTY1) ELISA Kit is specially designed for the accurate measurement of LEFTY1 levels in human samples such as serum, plasma, and cell culture supernatants. This kit offers high sensitivity and specificity, ensuring precise and reliable results for a variety of research applications.LEFTY1 is a key protein involved in the determination of left-right asymmetry in vertebrates during embryonic development. Dysregulation of LEFTY1 has been linked to various developmental disorders and diseases, making it a valuable biomarker for studying these conditions and potentially developing targeted therapies.
With this ELISA kit, researchers can uncover valuable insights into LEFTY1 expression levels, furthering our understanding of developmental processes and disease mechanisms. Trust in the accuracy and reliability of the Human LEFTY1 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.
