Nucleic acid elution

Abstract

This invention relates to the storage on a solid matrix of genetic material, in particular DNA that has been purified prior to the application to the solid matrix. More specifically, the invention relates to a solid matrix for the storage of purified DNA, which matrix has been treated with a solution comprising plant polysaccharide inulin. One advantage of the invention is that an increased amount of DNA can be stored in the solid matrix of the present invention.”

1 . A solid matrix suitable for the storage of purified DNA which matrix has been treated with a solution comprising inulin. 
     
     
         2 . The solid matrix of  claim 1 , which has also been treated with PEG. 
     
     
         3 . The solid matrix of  claim 1 , wherein the inulin treatment is at a concentration of up to 20%. 
     
     
         4 . The solid matrix of  claim 1 , which also contains PEG at up to 10%. 
     
     
         5 . A method of increasing of the yield of purified DNA eluted from a solid matrix by treating the solid matrix with a solution comprising inulin prior to the addition of said nucleic acid. 
     
     
         6 . The method of  claim 5 , wherein the solid matrix has also been treated with PEG or the DNA is applied in a buffer comprising PEG.
