Devices and methods of use and manufacture for the identification and characterization of analytes, e.g. proteins, are provided. The subject devices are characterized by having a substrate with a polymerized monomolecular film over at least a portion of the substrate, the monomolecular film having at least one ligand or specific binding pair member associated therewith. Preferably the monomolecular film is stable to the laser intensities employed in MALDI-MS. In certain embodiments, the ligands are biotin, integrin antagonists, antibodies and antigens. In using the subject devices, a subject device is contacted with a sample. If present in the sample, a member of the binding pair of interest binds to its complementary ligand and, once bound, can be analyze by mass spectroscopy techniques. Also provided are kits, which include the subject devices.
本发明提供了用于鉴定和表征蛋白质等分析物的装置和使用及制造方法。这些装置的特点是:有一个基底,基底的至少一部分上有一层聚合的单分子膜,单分子膜上有至少一个配体或特异性结合对成员。单分子膜最好对 MALDI-MS 中使用的激光强度稳定。在某些实施方案中,配体是生物素、整合素拮抗剂、抗体和抗原。在使用主体设备时,主体设备与样品接触。如果样品中存在感兴趣的结合配对,其成员就会与其互补配体结合,一旦结合,就可以通过质谱技术进行分析。此外,还提供了包括主题装置在内的试剂盒。
