產品描述：

豬膽囊收縮素/腸促胰酶肽(CCK)酶聯免疫試劑盒（CSB-E10131p）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的CCK含量。CCK即縮膽囊素，是一種胃腸道激素，在神經系統也作為神經遞質存在。其廣泛參與消化調節、攝食調控等生理過程。研究機制多聚焦于與CCK受體結合，激活下游信號通路，在消化、神經等領域開展研究，助力相關疾病治療策略探索。試劑盒檢測范圍為1.56 pg/mL-100 pg/mL，該產品適用于科研領域中對豬源性樣本CCK表達水平的定量研究，例如動物消化系統功能評估、神經肽作用機制探索或代謝調控相關實驗。通過兼容血清、血漿及多種組織樣本的檢測特性，本試劑盒為研究者提供靈活的實驗方案選擇，助力于豬模型在胃腸生理、神經生物學及代謝疾病機制等方向的科研工作。本品僅用于科研，不用于臨床診斷，產品具體參數及操作步驟詳見產品說明書。

線性度：

To assess the linearity of the assay, samples were spiked with high concentrations of pig CCK in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
	Sample	Serum(n=4)
1:1	Average %	97
	Range %	93-100
1:2	Average %	104
	Range %	101-107
1:4	Average %	91
	Range %	85-97
1:8	Average %	90
	Range %	87-93

回收率：

The recovery of pig CCK spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.

Sample Type	Average % Recovery	Range
Serum (n=5)	85	81-89
EDTA plasma (n=4)	92	87-98

Dietary Branched-Chain Amino Acids Regulate Food Intake Partly through Intestinal and Hypothalamic Amino Acid Receptors in Piglets Tian M,journal of agricultural and food chemistry,2019
Branched chain amino acids stimulate gut satiety hormone cholecystokinin secretion through the activation of the umami taste receptor T1R1/T1R3 using an in vitro porcine jejunum model Min Tian,Food & Function,2019

功能：

This peptide hormone induces gall bladder contraction and the release of pancreatic enzymes in the gut. Its function in the brain is not clear. Binding to CCK-A receptors stimulates amylase release from the pancreas, binding to CCK-B receptors stimulates gastric acid secretion.

1. We conclude that only a small fraction of neuronal CCK is nonsulfated. The intracellular distribution of nonsulfated CCK in neurons suggests that they contribute only modestly to the CCK transmitter activity. PMID: 27535680
2. Cardiac expression of pro-cholecystokinin is cell-specific, which differentiates the expression from that of intestinal endocrine cells and cerebral neurons. PMID: 25627687
