The Human LCT (Lactase) ELISA Kit is a highly reliable and accurate tool for detecting lactase levels in human samples such as serum, plasma, and cell culture supernatants. This kit offers excellent sensitivity and specificity, ensuring consistent and precise results for various research applications.Lactase is an important enzyme responsible for breaking down lactose in milk and dairy products. Deficiency in lactase can lead to lactose intolerance, causing digestive issues such as bloating, gas, and diarrhea.
Monitoring lactase levels can provide valuable insights into lactose tolerance and intolerance, as well as aid in the diagnosis and management of related conditions.Whether studying lactose metabolism, lactose intolerance, or dairy-related health concerns, the Human LCT ELISA Kit is an essential tool for researchers and healthcare professionals looking to investigate lactase levels and their impact on human health.

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.
