生物医学研究中对单克隆抗体(mAb)的需求很大,但目前用于发现它们的方法既耗时又昂贵。因此,可用于任何特定抗原的抗体的多样性仍然有限。微刻是一种软平版印刷技术,为发现新的mAb提供了快速有效的替代方案。该方案描述了如何使用微雕刻来筛选小鼠杂交瘤以建立产生独特mAb的新细胞系。将来自多克隆群体的单细胞分离到微量威尔斯孔阵列中(每个筛选约105个细胞)。然后用该阵列打印蛋白质微阵列,其中每个元件包含从各个威尔斯孔捕获的抗体。用感兴趣的抗原筛选微阵列上的抗体,并映射到相应的细胞,然后通过显微操作从它们的微孔中回收。筛选和回收需要大约1-3天(包括制备微孔阵列的步骤在内需要9-12天)。
The demand for monoclonal antibodies (mAbs) in biomedical research is significant, but the current methodologies used to discover them are both lengthy and costly. Consequently, the diversity of antibodies available for any particular antigen remains limited. Microengraving is a soft lithographic technique that provides a rapid and efficient alternative for discovering new mAbs. This protocol describes how to use microengraving to screen mouse hybridomas to establish new cell lines producing unique mAbs. Single cells from a polyclonal population are isolated into an array of microscale wells (~105 cells per screen). The array is then used to print a protein microarray, where each element contains the antibodies captured from individual wells. The antibodies on the microarray are screened with antigens of interest, and mapped to the corresponding cells, which are then recovered from their microwells by micromanipulation. Screening and retrieval require approximately 1–3 d (9–12 d including the steps for preparing arrays of microwells).
