    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 human SAA4 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

產品評價

靶點詳情

  • 最新研究進展：
    SAA4（serum amyloid A4）是SAA蛋白家族的一員，參與機體的免疫調節和炎癥反應。最新研究表明，SAA4在某些腫瘤中表達升高，與腫瘤的發生和進展密切相關。此外，SAA4也參與了許多炎癥和自身免疫疾病的發生和發展，成為新型治療策略的熱點研究對象。
  • 功能：
    Major acute phase reactant.
  • 基因功能參考文獻：
    1. Data identified SAA4 as a protein that was positively correlated with RF and RA. SAA4 may represent a novel prescreening marker for the diagnosis of RA. PMID: 28505104
    2. expressed in invasive trophoblast cells PMID: 24951172
    3. Six apolipoproteins (APOA1, APOA2, APOB, APOC2, APOC3, and APOE) were able to differentiate bladder cancer from hernia. SAA4 was significantly increased in bladder cancer subgroups, whereas ProEGF was significantly decreased in bladder cancer subgroups. PMID: 23631828
    4. studies provide the first evidence for a novel type of AA amyloidosis in which the fibrils were formed from a mutated SAA4 protein PMID: 20536400
    5. The sequences of 1478 and 1836 bp of the SAA1 and SAA4 5'-flanking regions were determined. PMID: 12410800
