產品詳情

  • 產品描述：
    雞胰島素樣生長因子1(IGF-1)酶聯免疫試劑盒（CSB-E09867Ch）為競爭法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的IGF1含量。IGF1即胰島素樣生長因子1，在細胞的生長、增殖和分化等過程中扮演重要角色。研究機制方面，它主要通過與IGF1受體結合，激活下游信號通路，影響細胞的存活、代謝等。其異常表達與多種疾病如腫瘤、糖尿病等密切相關，是相關研究的重要靶點。試劑盒檢測范圍為125 pg/mL-2000 pg/mL，該產品可廣泛應用于家禽生長發育機制研究、營養代謝實驗、繁殖生理學分析以及激素調控相關的基礎科研領域，為實驗室提供穩定可靠的檢測工具。試劑盒配套包含標準品、檢測板、生物素標記物及顯色試劑等完整組分，操作流程標準化，適用于生命科學、動物醫學等領域的科研實驗需求。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：
    The insulin-like growth factors, isolated from plasma, are structurally and functionally related to insulin but have a much higher growth-promoting activity. Acts as a ligand for IGF1R. Binds to the alpha subunit of IGF1R, leading to the activation of the intrinsic tyrosine kinase activity which autophosphorylates tyrosine residues in the beta subunit thus initiatiating a cascade of down-stream signaling events leading to activation of the PI3K-AKT/PKB and the Ras-MAPK pathways. Binds to integrins. Its binding to integrins and subsequent ternary complex formation with integrins and IGFR1 are essential for IGF1 signaling.
  • 基因功能參考文獻：
    1. It is a protein synthesis-related factor. PMID: 28594135
    2. The coding region of the IGF1 gene was polymorphic, expressed differentially during the pre-hatch and post-hatch periods, and haplogroups showed significant association with growth traits in chicken. PMID: 26059224
    3. The IGF-I gene is significantly associated with some growth traits (body weight at hatching, and at 4, 8, 12, and 14 weeks of age) in chickens. PMID: 23546986
    4. IGF1 single-nucleotide polymorphism c.47673G > A was associated with body weight and haematocrit percentage, and also with feed intake and percentages of abdominal fat and gizzard genotype x sex interactions. PMID: 23275255
    5. Insulin-like growth factor 1 stimulates Non-astrocytic Inner Retinal Glial cells to proliferate, migrate distally into the retina, and become reactive. PMID: 22973454
    6. The objective of this study was to examine associations of an IGF1 promoter polymorphism with growth, body composition, skeleton integrity, and metabolic traits in chickens. PMID: 15742956
    7. Genetic/nutritional models show a positive relation between muscle IGF-1 mRNA levels, which determine paracrine IGF-1 levels, and post hatch muscle growth. (Review) PMID: 16077194
    8. These results suggest that the mechanism of action whereby IGFBP2 excess impairs long bone development is to inhibit IGF-I and IGF-II mediated proliferation and matrix synthesis. PMID: 16183342
    9. Polymorphisms within the IGF1 gene are associated with 5-week body weight. PMID: 16734694
    10. Blood levels ofIGF-I may be more important than IGF-II after chicken hatching PMID: 17369538
    11. Data show that transcription level of IGF-1 decreased dramatically in the sex-linked dwarf. PMID: 17681929
    12. Association analysis showed that haplotypes based on three cIGF1 polymorphisms (c.-366A>C, c.528G>A and c.*1024C>T) were associated with body weight traits, suggesting that cIGF1 or a tightly linked gene had effects on body weight in the chicken. PMID: 18717967
    13. IGF-1 genes and proteins are expressed at high or moderately high levels in healing tendon PMID: 19084187
