產品詳情

  • 產品描述：
    人白細胞衍生趨化因子-2(LECT2)酶聯免疫試劑盒（CSB-EL012855HU）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿、組織培養上清液樣本中的LECT2含量。LECT2是一種白細胞來源的趨化因子，與肝纖維化密切相關。其研究機制表明，LECT2在正常生理條件下主要表達于肝臟細胞和中性粒細胞中，在炎癥條件下可加重肝纖維化。研究還發現，LECT2通過調控巨噬細胞增強對細菌的清除能力，并可能作為肝纖維化的診斷和治療靶點。試劑盒檢測范圍為1.56 ng/mL-100 ng/mL，該產品可廣泛用于基礎醫學研究中LECT2表達動態監測，例如肝臟疾病模型中的蛋白分泌研究、炎癥微環境分析、細胞因子網絡互作機制探索，以及藥物干預實驗中的生物標志物定量評估，為免疫調控機制和病理生理學研究提供可靠工具。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。

  • 功能：
    Has a neutrophil chemotactic activity. Also a positive regulator of chondrocyte proliferation. Does not show metalloendopeptidase activity.

    1. Overexpression of LECT2 or treatment with a recombinant LECT2 protein impaired the colony-forming ability and motility of non-small cell lung cancer cells harboring high levels of activated EGFR and MET. PMID: 30453282
    2. Circulating LECT2 concentrations were increased in individuals with NAFLD and those with MetS, but not in those with atherosclerosis. The relationship between LECT2 and both NAFLD and MetS might be mediated by its association with abdominal obesity and lipid metabolism. PMID: 28376109
    3. VFA was the strongest predictor of plasma LECT2 that is a potential biomarker linking visceral obesity to dyslipidemia PMID: 28278265
    4. LECT2 was found to be catalytically inactive as a metalloendopeptidase against various types of peptide sequences, including pentaglycine. PMID: 27334921
    5. the tissue levels of THBS2 and LECT-2 may correlate with the stage of atherosclerosis. PMID: 28039493
    6. findings indicated that serum LECT2 level is negatively associated with the presence of diabetic retinopathy and suggest that low circulating LECT2 level is a risk factor for diabetic retinopathy PMID: 27816666
    7. LECT2 amyloidosis is prevalent among Hispanic decedents in New Mexico. PMID: 26912093
    8. ALECT2, which was initially thought to affect mainly Hispanics in the United States, appears to represent an important and likely underrecognized etiology of chronic kidney disease among Egyptians and probably in other ethnic groups around the world PMID: 26867784
    9. Localized LECT2 amyloidosis of the adrenal gland with coexisting MGUS: a diagnostic challenge. PMID: 26048244
    10. LECT2 immunostain is useful in confirming subtype of amyloid within the liver in ALECT2.. PMID: 25602789
    11. Amyloidosis derived from leukocyte chemotactic factor 2 (ALECT2) is a recently described disease. Here, we report the characteristics and outcome of 72 patients with renal ALECT2, which included 19 who had another kidney disease on biopsy. PMID: 24451324
    12. There were no mutations detected in the LECT2 gene, although all renal leukocyte chemotactic factor 2 amyloidosis patients tested were homozygous for the G nucleotide in a non-synonymous SNP at position 172. PMID: 24522497
    13. LECT2 is regulated by beta-catenin in HCC in both mice and men, but serum LECT2 reflects beta-catenin activity only in mice. Serum LECT2 could be a potential biomarker of HCC in patients. PMID: 24892551
    14. First Nations people from British Columbia who presented with chronic kidney disease, were found to be due to LECT2 amyloidosis. PMID: 25064673
    15. The study indicates that serum LECT2 levels are increased by obesity and fatty liver, and suggests that LECT2 is a novel obesity-related protein. PMID: 24390366
    16. The data from this study show that weak LECT2 staining should be regarded as indeterminate or a negative result and does not per se allow diagnosis of specific amyloid type. The diagnosis of LECT2 renal amyloidosis may require LMD/MS confirmation. PMID: 24792621
    17. These results demonstrate the involvement of LECT2 in glucose metabolism and suggest that LECT2 may be a therapeutic target for obesity-associated insulin resistance. PMID: 24478397
    18. ALect2 is a common cause of hepatic amyloidosis in the population of the United States, and subtyping hepatic amyloid deposits by an accurate analytic method such as MS is required for optimal clinical management of hepatic amyloidosis patients PMID: 24415538
