    • A system for collecting target nucleic acids from a sample can include at least one sample chamber configured to receive a sample containing target nucleic acids and other material, at least one collection chamber removably mountable relative to the at least one sample chamber and configured to collect target nucleic acids separated from the other material, a filter removably mountable relative to the at least one sample chamber and configured to be disposed between the at least one sample chamber and the at least one collection chamber when the at least one collection chamber is mounted relative to the at least one sample chamber. The system may further include a pair of electrodes configured to generate an electric field sufficient to cause target nucleic acids in the at least one sample chamber to migrate via electrophoresis from the at least one sample chamber through the filter into the at least one collection chamber, wherein the filter may be configured to permit passage of target nucleic acids and to block passage of material of a size larger than the target nucleic acids.
    • 用于从样品收集目标核酸的系统可以包括至少一个样品室,其被配置为接收含有靶核酸和其它材料的样品,至少一个收集室,其相对于至少一个样品室可拆卸地安装并且被配置成收集目标 与其他材料分离的核酸,相对于至少一个样品室可拆卸地安装的过滤器,并且被配置为当所述至少一个收集室相对于所述至少一个收集室安装时,被设置在所述至少一个样品室和所述至少一个收集室之间 所述至少一个样品室。 该系统可以进一步包括一对电极,其被配置为产生足以使所述至少一个样品室中的靶核酸经由电泳从所述至少一个样品室通过所述过滤器迁移到所述至少一个收集室中的电场, 其中所述过滤器可以被配置为允许靶核酸的通过并阻止尺寸大于所述靶核酸的材料的通过。
