產品描述：

人補體因子H相關蛋白2(CFHR2)酶聯免疫試劑盒（CSB-EL005275HU）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的CFHR2含量。CFHR2屬于補體因子H相關基因家族，位于染色體1上，參與補體調節。其突變與致密性沉積病和非典型溶血性尿毒癥綜合征有關。研究顯示，CFHR2可能通過調節補體系統活性，影響脂質代謝，在免疫調節中發揮重要作用。試劑盒檢測范圍為6.25 ng/mL-400 ng/mL，適用于體外細胞實驗、疾病機制研究及生物標志物探索等科研場景，可為補體相關疾病的分子機制解析、藥物靶點驗證及治療策略開發提供精準的定量分析工具，尤其適合免疫學、病理學及轉化醫學領域的實驗室使用本品僅用于科研，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 human CFHR2 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
	Sample	Serum(n=4)
1:100	Average %	91
	Range %	87-95
1:200	Average %	96
	Range %	90-102
1:400	Average %	104
	Range %	98-109
1:800	Average %	92
	Range %	86-98

回收率：

The recovery of human CFHR2 spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.

Sample Type	Average % Recovery	Range
Serum (n=5)	101	97-105
EDTA plasma (n=4)	94	87-98

產品評價

靶點詳情

功能：

Involved in complement regulation. The dimerized forms have avidity for tissue-bound complement fragments and efficiently compete with the physiological complement inhibitor CFH. Can associate with lipoproteins and may play a role in lipid metabolism.
基因功能參考文獻：
1. Studies indicate an association between CFHR2-rs2986127 and acute anterior uveitis (AAU) diagnosis. PMID: 27306586
2. Next-generation sequencing of the CFH region identified putatively functional variants (missense, splice site and indel) on the four common haplotypes. We found no expression of any of the five CFH-related genes in the retina or RPE/Choroid/Sclera, in contrast to the liver, which is the main source of the circulating proteins. [CFHR2] PMID: 27196323
3. Thus CFHR2 likely acts in concert with factor H, as CFHR2 inhibits convertases while simultaneously allowing factor H assisted degradation by factor I. PMID: 24260121
4. A hybrid CFHR2-CFHR5 plasma protein, arising from a chromosomal deletion mutation stabilizes the C3 convertase and reduces factor H-mediated convertase decay. PMID: 24334459
亞細胞定位：

Secreted.
組織特異性：

Expressed by the liver and secreted in plasma.
