產品描述：人補體片斷3b(C3b)酶聯免疫試劑盒（CSB-E09303h）為雙抗夾心法ELISA試劑盒，定量檢測血清、尿液、腦脊液（CSF）、唾液樣本中的C3b含量。C3b是補體系統中的重要分子。其背景在于補體系統是免疫防御的關鍵部分。研究機制方面，C3b參與調理吞噬作用，能與病原體結合促進吞噬細胞識別吞噬；還參與補體激活的旁路途徑，在免疫調控、炎癥反應等過程中發揮著重要作用。試劑盒檢測范圍為3.12 ng/mL-200 ng/mL，本產品適用于基礎醫學研究中對補體系統活性的動態監測，例如探究感染性疾病、神經炎癥或慢性炎癥模型中C3b的生物學功能，也可用于評估藥物或生物制劑對補體活化途徑的調控作用。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 C3b 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 % 87 Range % 82-92 1:2 Average % 98 Range % 92-103 1:4 Average % 99 Range % 93-103 1:8 Average % 94 Range % 89-98 -
回收率：
The recovery of human C3b 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 90-98 EDTA plasma (n=4) 97 91-99 -

產品評價
平均分:
樣品類型：生物流體 肺泡灌洗液
樣品信息：人
稀釋比：其他 1：2
產品評價： 我使用CSB-E09303h檢測MPP組以及無肺炎表現異物堵塞患者肺泡灌洗液中C3b濃度，空白稀釋液OD為0.163，標準曲線的R=0.999258，樣本稀釋2倍后進行檢測，極個別（3個）樣本濃度低于檢測下限，但考慮到部分樣本濃度偏高，仍建議使用兩倍稀釋進行實驗。試劑盒符合實驗要求，推薦使用
