Automatable method for preparing samples which can be universally applied

摘要

Isolation of an analyte (I) from a biological sample comprising: (i) decomposing the sample in a reaction vessel; (ii) adding a solid adsorption matrix (A); (iii) incubating so that (I) binds to (A); (iv) removing non-bound components from the vessel; (v) incubating so that (I) is eluted from (A); and (vi) separating the eluate from (A). Independent claims are also included for the following: (1) reagent kits for the process comprising protease; buffers for sample decomposition, washing and elution, and a suspension of magnetic glass particles; (2) apparatus for the process; and (3) magnetic glass particles (B) comprising a magnetic core and glass shell containing silica, boron oxide and alkali metal oxide, optionally also alumina and alkaline earth metal oxide.
