1. System for stabilizing, conserving and storing of a nucleic acid, comprising:
a test tube having a body and an opening which is closed with a first closing element to create an interior within the body of the test tube and wherein said interior is sterile, wherein the first closing element has a first diameter, a stabilization mixture within the interior of the test tube and comprising ammonium chloride and/or polyvinylpyrrolidone, a denaturant, a chelator and a buffer for stabilizing, conserving and storing said nucleic acid, a funnel comprising an open conical element and a tube element, wherein the tube element is adapted to fit to the opening of the test tube, and a second closing element, wherein the second closing element is adapted to sealably fit the opening of the test tube, wherein the second closing element has a second diameter and wherein the first diameter and second diameter are the same wherein the stabilization mixture comprises polyvinylpyrrolidone and CTAB as a denaturant. |
