產品描述：

大鼠骨形態形成蛋白拮抗蛋白酶聯免疫試劑盒（CSB-E17688r）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿、細胞裂解物樣本中的GREM1含量。GREM1作為靶點，在機體胚胎發育、組織修復等過程中發揮重要作用。研究發現它能通過調控BMP信號通路等影響細胞的增殖、分化和凋亡，與多種疾病如腫瘤、骨疾病等發生發展相關，對其深入研究有助于開發新的治療策略和藥物。試劑盒檢測范圍為1.56 ng/mL-100 ng/mL，適用于體外培養細胞模型、動物實驗樣本中BMP拮抗蛋白的定量分析，可支持骨骼生物學研究、信號通路調控機制探索以及相關疾病的分子機制解析，為藥物干預效果評估或病理模型構建提供可靠的檢測工具。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。

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 rat gremlin 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)
1:1	Average %	105
	Range %	101-109
1:2	Average %	96
	Range %	94-98
1:4	Average %	89
	Range %	83-95
1:8	Average %	93
	Range %	89-97

回收率：

The recovery of rat gremlin 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	99-104
EDTA plasma (n=4)	90	85-96

靶點詳情

功能：

Cytokine that may play an important role during carcinogenesis and metanephric kidney organogenesis, as a BMP antagonist required for early limb outgrowth and patterning in maintaining the FGF4-SHH feedback loop. Down-regulates the BMP4 signaling in a dose-dependent manner. Antagonist of BMP2; inhibits BMP2-mediated differentiation of osteoblasts (in vitro). Acts as inhibitor of monocyte chemotaxis. Can inhibit the growth or viability of normal cells but not transformed cells when is overexpressed.
