產(chǎn)品描述：

人ICOS配體(ICOSLG)酶聯(lián)免疫試劑盒（CSB-EL010958HU）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ICOSLG含量。ICOSLG，也稱為B7-H2或GL50，是一種跨膜糖蛋白，屬于B7配體家族。它在多種抗原呈遞細胞和非淋巴細胞上廣泛表達，作為T細胞共刺激分子，對T細胞的激活、增殖、分化和細胞因子產(chǎn)生起重要作用。研究機制涉及ICOSLG與ICOS受體的相互作用，以及其在免疫調(diào)節(jié)和疾病發(fā)生中的作用。試劑盒檢測范圍為93.75 pg/mL-6000 pg/mL，該產(chǎn)品適用于免疫調(diào)節(jié)機制研究、腫瘤免疫治療探索以及生物標志物分析等科研場景，為探索ICOSLG在免疫系統(tǒng)中的功能及調(diào)控網(wǎng)絡提供可靠工具。本品僅用于科研，不用于臨床診斷，產(chǎn)品具體參數(shù)及操作步驟詳見產(chǎn)品說明書。

線性度：

To assess the linearity of the assay, samples were spiked with high concentrations of human ICOSLG 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 %	88
	Range %	82-94
1:2	Average %	96
	Range %	89-102
1:4	Average %	98
	Range %	95-106
1:5	Average %	95
	Range %	91-100

回收率：

The recovery of human ICOSLG 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)	96	88-103
EDTA plasma (n=4)	94	90-100

標準曲線：

These standard curves are provided for demonstration only. A standard curve should be generated for each set of samples assayed.

功能：

Ligand for the T-cell-specific cell surface receptor ICOS. Acts as a costimulatory signal for T-cell proliferation and cytokine secretion; induces also B-cell proliferation and differentiation into plasma cells. Could play an important role in mediating local tissue responses to inflammatory conditions, as well as in modulating the secondary immune response by co-stimulating memory T-cell function.
亞細胞定位：

Cell membrane; Single-pass type I membrane protein.
蛋白家族：

Immunoglobulin superfamily, BTN/MOG family
組織特異性：

Isoform 1 is widely expressed (brain, heart, kidney, liver, lung, pancreas, placenta, skeletal muscle, bone marrow, colon, ovary, prostate, testis, lymph nodes, leukocytes, spleen, thymus and tonsil), while isoform 2 is detected only in lymph nodes, leuko
