The Human Calbindin (CALB) ELISA Kit is specifically designed for the quantitative measurement of calbindin levels in human serum, plasma, and cell culture supernatants. Calbindin is a calcium-binding protein that plays a key role in neuronal function and is involved in various physiological processes such as cell signaling and neurotransmitter release.This ELISA kit offers high sensitivity and specificity, ensuring accurate and reliable results for research applications focused on studying neurological disorders, neurodegenerative diseases, and calcium signaling pathways.
By providing a precise measurement of calbindin levels, researchers can better understand its role in these conditions and potentially develop targeted therapies. Overall, the Human Calbindin (CALB) ELISA Kit is a valuable tool for researchers seeking to explore the functions and implications of calbindin in various disease states, ultimately advancing our knowledge of neurobiology and potential treatment strategies.
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.
