產品詳情

  • 產品描述：
    牛催乳素(PRL/LTH)酶聯免疫試劑盒（CSB-E14002B）為競爭法ELISA試劑盒，定量檢測血清、血漿樣本中的PRL含量。催乳素（PRL）是一種由垂體前葉分泌的多肽激素，主要促進乳腺發育和乳汁分泌。其分泌受下丘腦-垂體軸調控，多巴胺等激素可抑制其分泌。催乳素在泌乳過程中起關鍵作用，其受體為跨膜糖蛋白，參與信號轉導。試劑盒檢測范圍為20 μIU/mL-8000 μIU/mL，本產品適用于畜牧業研究中泌乳機制探索、繁殖周期監測、應激水平評估等科研場景，為優化奶牛飼養管理或乳腺疾病研究提供數據支持。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。

靶點詳情

  • 功能：
    Prolactin acts primarily on the mammary gland by promoting lactation.
  • 基因功能參考文獻：
    1. Taken together, these results support novel functions of prolactin as a modulator of the innate immune response that do not involve the classical prolactin pathway. PMID: 26341952
    2. The presence and localization of prolactin receptor are consistent with expression data reported for other species, and the presence of PIP and prolactin in seminal fluid is consistent with data generated in humans. PMID: 25533929
    3. Functionally reciprocal mutations of the prolactin signaling pathway define hairy and slick cattle. PMID: 25519203
    4. The single nucleotide polymorphism rs42646708 of cattle XKR4 was significantly associated with serum prolactin concentrations and explained 2.45% of the phenotypic variation. PMID: 24666329
    5. Five mutations were identified in exonic region and eleven in associated intronic regions in PRL gene in 100 cattle from four Pakistani cattle breeds. PMID: 24065524
    6. this study identifies a biochemical mechanism for the regulation of SCFAs on bovine GH and PRL gene transcription in dairy cow anterior pituitary cells PMID: 24177567
    7. These data suggest that PRL protects brain endothelial cells against methamphetamine-induced toxicity PMID: 23988027
    8. Bovine prolactin improved the expression of human transferrin through such a possible mechanism that bovine prolactin activated STAT5a transcription expression. PMID: 22829284
    9. There was no significant difference between 1134 locus and milk performance traits of 5'-UTR of PRL gene PMID: 22207382
    10. Staphylococcus aureus infection inhibits nuclear factor kappa B activation mediated by prolactin in bovine mammary epithelial cells. PMID: 21843629
    11. Study of genetic variation in Yakutian cattle (Bos taurus L.) using the prolactin bPRL, growth hormone bGH, and transcription factor bPit-1 genes PMID: 20391788
    12. This is the second study reporting single nucleotide polymorphisms in the 5'-regulatory region of PRL gene, which interfere with milk production traits. PMID: 19714484
    13. evidence for a functional coupling between the PRL salt bridge and phosphorylation site indicates that either in vivo phosphorylation or specific mutations that destabilize the salt bridge impair biological activity. PMID: 12850287
    14. determination of the effects of exposure to different lengths of daylight during the dry period on circulating PRL and PRL receptor mRNA expression in lymphocytes and mammary tissue during the transition to lactation PMID: 15591374
    15. Expression of PRL and prolactin receptor (PRLR) mRNA is demonstrated for the first time in bovine corpus luteum throughout the luteal phase. PMID: 16435374
    16. The A-->G transition at position -1043 abolishes the recognition site for Hsp92II restriction endonuclease. PMID: 17929163
    17. Prolactin in ovarian follicular fluid stimulates endothelial cell proliferation. PMID: 19672107
