The Human Histidine Ammonia Lyase (HAL) ELISA Kit is specifically designed for the accurate measurement of HAL levels in human serum, plasma, and cell culture supernatants. This advanced kit provides high sensitivity and specificity, ensuring precise and consistent results for a variety of research applications.Histidine Ammonia Lyase is an important enzyme that plays a key role in histidine metabolism, converting histidine to urocanic acid. Dysregulation of HAL activity has been linked to various health conditions such as histidinemia and certain types of cancer.
This ELISA kit offers researchers a valuable tool to explore the role of HAL in disease development and progression, as well as potential therapeutic interventions. Get reliable and insightful data with the Human Histidine Ammonia Lyase ELISA Kit, a must-have for researchers investigating histidine metabolism and its implications for 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.
