The Human FMS-like tyrosine kinase 3 (FLT3) ELISA Kit is a reliable tool for detecting and quantifying FLT3 levels in human samples including serum, plasma, and cell culture supernatants. With its high sensitivity and specificity, this kit provides accurate and reproducible results, making it suitable for a variety of research applications.FLT3 is a key protein involved in regulating cell growth, differentiation, and survival. Abnormalities in FLT3 expression and activity have been linked to various hematologic malignancies, including acute myeloid leukemia (AML) and certain types of lymphoma.
Understanding FLT3 levels can provide valuable insights into disease progression and potential treatment strategies.By using the Human FLT3 ELISA Kit, researchers can gain a deeper understanding of FLT3's role in disease pathogenesis and progression, ultimately paving the way for the development of targeted therapies for FLT3-associated disorders.
Matrices listed below were spiked with certain level of recombinant the index and the recovery rates were calculated by comparing the measured value to the expected amount of the index in 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.
