1.抗体(蛋白)芯片 细胞因子的免疫学检测原理 A.Sandwich B.Competitive C.Direct Label D.Label-free Method Method Method Method Signal detection in most antibody arrays relies on common labels(biotin,fluors,or enzymes)attached to the antibody or antigen.The sandwich method(A)requires an immobilized capture antibody and a labeled,in-solution detection antibody.This method has the advantages of excellent specificity and sensitivity.The competitive method(B)relies on competitive binding between the analyte and a labeled antigen.In the direct-label method(C),the label is attached to the analyte itself,while the label-free method(D)relies on an inherent property of the analyte(such as mass per unit area or surface plasmon resonance) to produce a signal
Sandwich Method Direct Label Method Competitive Method Label-free Method A. B. C. D. Signal detection in most antibody arrays relies on common labels (biotin, fluors, or enzymes) attached to the antibody or antigen. The sandwich method (A) requires an immobilized capture antibody and a labeled, in-solution detection antibody. This method has the advantages of excellent specificity and sensitivity. The competitive method (B) relies on competitive binding between the analyte and a labeled antigen. In the direct-label method (C), the label is attached to the analyte itself, while the label-free method (D) relies on an inherent property of the analyte (such as mass per unit area or surface plasmon resonance) to produce a signal. 细胞因子的免疫学检测原理 II. 抗体(蛋白)芯片
