The Rat Beta-Endorphin (BEP) ELISA Kit is specifically designed for the precise quantification of beta-endorphin levels in rat serum, plasma, and tissue homogenates. With its exceptional sensitivity and specificity, this kit provides accurate and reproducible results, making it an invaluable tool for various research applications.Beta-endorphin is a neurotransmitter and hormone that plays a crucial role in the body's response to stress, pain, and pleasure. Dysregulation of beta-endorphin levels has been linked to various physiological and psychological disorders, making it a key biomarker for studying conditions such as chronic pain, addiction, and mood disorders.
By accurately measuring beta-endorphin levels, researchers can gain valuable insights into the underlying mechanisms of these disorders and potentially develop new therapeutic approaches. The Rat Beta-Endorphin ELISA Kit offers a convenient and reliable solution for studying beta-endorphin dynamics in a laboratory setting.

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 condition. 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.
