Lensless SPR Technology
以往傳統 SPR 系統是使用角檢測 (angular interrogation) 產生 SPR 信號,需要大約 50 cm 的傾斜光路。此方法需要複雜且精密的透鏡,以確保光線正確聚焦到感測表面,然后收集到檢測器上。相比之下,無透鏡 SPR 系統的光路呈線性,且長度大約是傳統 SPR 系統的 1/10,這種線性光路消除了對透鏡的需求,从而顯著减小 SPR 系统主要組件的尺寸,使儀器整體體積可以大幅縮小。

Comparing static and kinetic SPR characteristics
SPR 儀器可以提供豐富的分子相互作用資訊,例如動力學、親和力和濃度等。 利用 SPR 進行分析主要分為兩種類型:靜態分析和動態分析。通過結合使用靜態和動態分析,我們可以全面瞭解分子相互作用。動態分析説明我們揭示結合的動態特性,而靜態分析則允許高效篩選和定量。兩者結合起來,可以提供從初始結合到穩態結合水平的整個結合過程的整體視圖。
- 靜態分析系統 (static system):例如 P4SPR 儀器,樣品溶液通過注射器手動注入流動池,並通過擴散與表面相互作用,其非常適合用於分析物篩選和定量。它可以在特定時間點提供結合的即時結果,從而快速分析大量樣品組。由於簡化的樣品引入過程、更快的基線建立和高效的系統沖洗,靜態 SPR 的分析時間可以比動態 SPR 縮短一半。這使得靜態 SPR 成為特異性篩選、分析物定量和基本親和力表徵的省時選擇。
- 動態分析系統 (kinetic system):樣品通過進樣環 (sample loop) 載入(手動注射器或自動進樣器),然後通過注射幫浦驅動流動緩衝液,將樣品引入流動池中。讓我們能夠瞭解分子相互作用的動態特性,揭示結合的速度和強度。它有助於研究生物過程的機制並開發標靶治療方法。通過即時監測相互作用,我們可以評估結合速率和解離速率,並推導出親和力常數。

英文說明
- Lensless SPR Technology
n traditional Surface Plasmon Resonance (SPR) systems, angular interrogation is utilized to generate the SPR signal, requiring an angled optical path of approximately 50 cm. This method employs complex and delicate lenses to ensure proper focusing of light onto the sensing surface and then collection onto the detector.
In contrast, lensless SPR systems feature a linear optical path that is approximately 10 times shorter than that of traditional SPR systems. This linear path eliminates the need for lenses, thereby offering the potential to significantly reduce the size of the main components of the SPR system, making it ultra-compact. Affinité's lensless SPR technology represents a game-changing leap in the world of SPR instruments. By streamlining the traditional complexities, we have achieved a more compact and efficient design, making it easier than ever to harness the power of SPR. With its patented features, such as the integration of a Dove prism and the strategic use of broad-spectrum LEDs, our lensless SPR technology promises to transform the way you conduct your analysis.
- Comparing static and kinetic SPR characteristics
Both kinetic and static analyses provide valuable information in different ways. Kinetic analysis allows us to understand the dynamics of molecular interactions by providing insights into the speed and strength of binding. It helps study the mechanisms of biological processes and develop targeted therapies. By monitoring interactions in realtime, we can evaluate association and dissociation rates and derive affinity constants. On the other hand, static analysis is well-suited for screening and quantification of analytes. It provides a snapshot of binding at a specific time point, allowing for rapid analysis of large sample sets. Assay times in static SPR can be up to half the time as kinetic SPR due to the simplified sample introduction process, quicker baseline establishment, and efficient system flushing. This makes static SPR a time-efficient choice for specificity screening, analyte quantification, and basic affinity characterization. By utilizing both kinetic and static analyses, we can obtain a comprehensive understanding of molecular interactions. Kinetic analysis helps us uncover the dynamic aspects of binding, while static analysis allows for efficient screening and quantification. Together, they provide a holistic view of the binding process, from the initial association to the steady-state binding levels.
