Rat Left/Right Determination Factor 1 (LEFTY1) ELISA Kit
The Rat Left-Right Determination Factor 1 (Lefty1) ELISA Kit is specifically designed for the accurate measurement of Lefty1 levels in rat samples such as serum, plasma, and cell culture supernatants. This kit provides researchers with high sensitivity and specificity, ensuring reliable and reproducible results for a variety of research applications.Lefty1 is a key protein involved in the determination of left-right asymmetry during development, making it a crucial factor in embryonic patterning.
Its dysregulation has been linked to various developmental disorders and diseases, making it an important biomarker for studying these conditions and potentially developing therapeutic interventions.Overall, the Rat Left-Right Determination Factor 1 (Lefty1) ELISA Kit is a valuable tool for researchers looking to further understand the role of Lefty1 in development and disease, providing them with the means to accurately quantify its levels in rat 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 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.
