產品詳情

  • 產品描述：
    大鼠多肽YY/酪酪肽(PYY)酶聯免疫試劑盒（CSB-E13432r）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織培養上清液、組織勻漿樣本中的PYY含量。PYY（肽YY）是一種由腸道內分泌細胞產生的激素，主要功能是調節食欲和抑制胰腺分泌。近期研究發現，PYY還具有抗菌肽功能，在維持腸道健康和免疫平衡中發揮重要作用。其研究機制涉及PYY與神經肽Y受體結合，調節食欲和腸道微生物組，為肥胖、糖尿病等疾病的治療提供了新的靶點。試劑盒檢測范圍為7.8 pg/mL-500 pg/mL，適用于科研領域中對大鼠模型能量代謝機制、胃腸功能調控或肥胖相關疾病的研究，例如通過檢測血清或組織中的PYY水平評估飲食干預、藥物處理或基因修飾對代謝通路的影響，亦可用于體外細胞實驗探究激素分泌調控機制。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。

  • 精密度：
    Intra-assay Precision (Precision within an assay): CV%<8%
    Three samples of known concentration were tested twenty times on one plate to assess.
    Inter-assay Precision (Precision between assays): CV%<10%
    Three samples of known concentration were tested in twenty assays to assess.
  • 線性度：
    To assess the linearity of the assay, samples were spiked with high concentrations of rat PYY in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

  • 功能：
    This gut peptide inhibits exocrine pancreatic secretion, has a vasoconstrictory action and inhibitis jejunal and colonic mobility.

    1. Peptide YY mediates the satiety effects of diets enriched with whey protein fractions in male rats PMID: 29042449
    2. Additional analysis of the findings demonstrated significant interactions of ovarian cycle stage and fed/fasted status with age on GLP-1, but not PYY plasma concentrations PMID: 28237410
    3. These findings indicate that the mechanism underlying type 2 diabetes remission may be mediated by PYY. PMID: 27117413
    4. Serum PYY levels were nonsignificantly decreased in rats with human neuroblastoma and hepatoblastoma transplants. PMID: 25111274
    5. gut PYY(3-36) action at Y2 receptors peripheral to the blood brain barrier plays an essential role in mediating satiety PMID: 23482449
    6. RACK1 modulates the ability of preglomerular vascular smooth muscle cells to respond to the proliferative actions of PYY. PMID: 23303411
    7. Exercise in hypoxia suppressed hunger and increased PYY but did not influence ad libitum energy intake. PMID: 22114179
    8. PYY concentrations in plasma, descending colon and rectum tissues were increased (P < 0.001) throughout pregnancy and lactation. PYY peaked at day 5 of lactation in plasma, as well as descending colon and rectum tissues. PMID: 19778563
    9. PYY induced a contraction of smooth muscle strips from proximal colon, but not on smooth muscle from any other gut segments. PMID: 12383864
    10. findings indicate that insulin-like growth factor-I functions as a positive regulator of peptide YY gene expression and that the stimulatory effect may be mediated by Sp1 proteins PMID: 14592960
    11. PYY(3-36) might play a role in the neuroendocrine modulation of the reproductive axis PMID: 15564330
    12. observations indicate that Peptide YY (PYY) levels are influenced by age, thyroid hormones, and growth hormone and indicate that PYY could be involved in the changes of food intake associated with these conditions PMID: 15687395
    13. study indicates that peripheral Peptide YY (PYY) may transmit satiety signals to the brain in part via the vagal afferent pathway PMID: 15718279
    14. PYY-immunoreactive (ir) cell bodies were localized exclusively to the gigantocellular reticular nucleus (Gi) of the rostral medulla. The highest density of PYY fibers was present within the solitary tract nucleus. PMID: 18022952
    15. Demonstrate the development of a potent homeostatic response to increase food intake when PYY(3-36) reduces food intake and energy reserves in diet-induced obese rats. PMID: 18550871
