The present invention relates to a method of producing a solid carrier, to which at least one affinity-reagent is coupled that binds specifically to a target molecule, comprising the steps of (i) coupling at least one affinity-reagent to a solid carrier, (ii) overlaying the affinity-reagent-coupled carrier obtained in (i) by incubation with a composition comprising heparin and/or a functional derivative thereof, and (iii) overlaying the affinity-reagent-coupled carrier by incubation with a composition comprising stabilising excipients, wherein steps (ii) and (iii) are carried out subsequently or simultaneously and subsequently to step (i). The invention further relates to a solid carrier comprising (i) at least one affinity-reagent, wherein the at least one affinity-reagent is coupled to the solid carrier, (ii) an overlay comprising heparin and/or a functional derivative thereof, and (ii) an overlay comprising stabilising excipients. In addition, the invention relates to the use of the carrier of the invention or of the carrier produced by the method of the invention to specifically bind and enrich a target molecule or a target cell which carries a biological target molecule on its surface from a liquid sample. Further, the invention relates to the use of the carrier of the invention or of the carrier produced by the method of the invention to specifically induce a biological response in a target cell. Furthermore, the invention relates to an ex-vivo or in-vitro method for specifically binding and enriching a target cell out of a liquid sample comprising contacting the liquid sample with the carrier of the invention or the carrier produced by the method of the invention, wherein the contacting is effected by inducing the liquid sample to flow over the surface of the carrier to which the at least one affinity-reagent is coupled, and wherein the target cell carries a biological target molecule on its surface to which the at least one affinity-reagent specifically binds. Moreover, the invention relates to the carrier of the invention or the carrier produced by the methods of the invention for use as an implant or as an extracorporeal device.
本发明涉及一种生产固体载体的方法,在该载体上耦合了至少一种能与目标分子特异性结合的亲和试剂,该方法包括以下步骤:(i) 将至少一种亲和试剂耦合到固体载体上、(ii) 将(i)中获得的亲和试剂偶联载体与包含肝素和/或其功能衍生物的组合物孵育,以及 (iii) 将亲和试剂偶联载体与包含稳定辅料的组合物孵育,其中步骤(ii)和(iii)在步骤(i)之后或同时进行。本发明还涉及一种固体载体,包括(i)至少一种亲和试剂,其中至少一种亲和试剂与固体载体偶联;(ii)由肝素和/或其功能衍生物组成的覆盖层;以及(ii)由稳定辅料组成的覆盖层。此外,本发明还涉及使用本发明载体或通过本发明方法生产的载体从液体样品中特异性结合和富集靶分子或表面携带生物靶分子的靶细胞。此外,本发明还涉及使用本发明的载体或本发明方法制备的载体特异性地诱导靶细胞产生生物反应。此外,本发明还涉及一种体内或体外方法,用于从液体样品中特异性结合和富集靶细胞,该方法包括将液体样品与本发明的载体或通过本发明的方法生产的载体接触,其中接触是通过诱导液体样品流过至少一种亲和试剂耦合的载体表面来实现的,其中靶细胞表面携带生物靶分子,至少一种亲和试剂与之特异性结合。此外,本发明还涉及本发明的载体或通过本发明方法生产的载体,可用作植入物或体外装置。
