Human Cholecystokinin B Receptor (CCKBR) ELISA Kit
The Human Cholecystokinin B Receptor (CCKBR) ELISA Kit is a reliable tool designed for the accurate quantification of CCKBR levels in human serum, plasma, and cell culture supernatants. This kit is highly sensitive and specific, ensuring precise and reproducible results for a variety of research applications.The CCKBR is a crucial receptor involved in mediating the effects of cholecystokinin, a peptide hormone that regulates digestion and appetite. Dysregulation of CCKBR signaling has been linked to various gastrointestinal disorders, making it a valuable biomarker for studying these conditions and developing potential therapeutic interventions.
Utilizing this ELISA kit allows researchers to measure CCKBR levels with confidence, gaining valuable insights into the role of this receptor in health and disease. Whether investigating gastrointestinal diseases or exploring new treatment options, the Human CCKBR ELISA Kit provides a powerful tool for advancing scientific understanding in this field.

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.
