產品描述：

人1,4,5-三磷酸肌醇(IP3)酶聯免疫試劑盒（CSB-E12636h）為競爭法ELISA試劑盒，定量檢測血清、血漿、組織培養上清液、組織勻漿樣本中的IP3含量。IP3即三磷酸肌醇，是細胞內重要的第二信使。其背景在于它在細胞信號轉導中扮演關鍵角色。研究機制上，當細胞外信號激活相應受體，通過G蛋白激活磷脂酶C，水解磷脂酰肌醇生成IP3，它能促使內質網釋放Ca2?，引發一系列細胞反應。試劑盒檢測范圍為5 pg/mL-1000 pg/mL，尤其適用于體外研究細胞信號通路激活程度、藥物靶點作用機制或疾病模型中IP3動態變化的分析；為探究G蛋白偶聯受體介導的磷酸肌醇代謝、細胞應激反應調控等基礎研究提供可靠工具，廣泛適配于神經生物學、藥理學及病理生理學等領域的科研需求。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。

線性度：

To assess the linearity of the assay, samples were spiked with high concentrations of human IP3 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 %	95
	Range %	90-105
1:2	Average %	94
	Range %	89-100
1:4	Average %	94
	Range %	87-102
1:8	Average %	95
	Range %	90-102

回收率：

The recovery of human IP3 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)	95	91-100
EDTA plasma (n=4)	92	87-96

■ 常見問題解答

I would like to receive more information about this assay, particularly regarding specificity for IP3.
Please provide some more information about the following.
a. capture antibody or capture antigen
b. Detection antibody (if applicable)
c. standard – if recombinant protein please specify sequence (including species source and accession no. if available) and expression host.
Are you aware of any product specific references for this assay? If yes please can you provide links to these references. If you have any other information about validation of the antibodies in other applications e.g. WB this information would be helpful also.

Thanks for your inquiry.
CSB-E12636h
This is a competitive kit.
The plate is coated with goat-anti-rabbit antibody.
The specific antibody is rabbit polyclonal antibody.
The standard is purified IP3.
The raw materials of the kit have been screened strictly and passed quality control. Sorry it is not convenient for us to provide validation information of the antibodies because it is only for our internal tracing. There are many references about this kit. Pls find following links:
