pBR328-Marker, DNA-marker, ready-to-use, 2 ml, plasticpBR328 Marker, DNA marker, ready to use, not pre dyed, Storage temp. 20 C Irregular DNA marker for analysis of small DNA fragments. The marker was manufactured by mixing fragments obtained by restriction digest of pBR328 using the endonucleases Hinf I and Bgl I. Directions for use Made from natural plasmids: fragment sizes can be validated! The concentration of the individual fragments is equimolar so that rough quantitation of the analysed DNA is
