This package contains a mixture of 500µl of the four deoxyribonucleotide solutions (dATP, dCTP, dGTP and dTTP), each at 10mM. The nucleotides are supplied in sterile, doubly distilled water. The final concentrations for each of the four deoxyribonucleotides are: dATP: 10mM dATP (2'-deoxyadenosine 5'-triphosphate, sodium salt) C10H12N5O12P3Na4 F.W. 579.2 dCTP: 10mM dCTP (2'-deoxycytidine 5'-triphosphate, sodium salt) C9H12N3O13P3Na4 F.W. 555.1 dGTP: 10mM dGTP (2'-deoxyguanosine 5'-triphosphate, sodium salt) C10H12N5O13P3Na4 F.W. 595.1 dTTP: 10mM dTTP (2'-deoxythymidine 5'-triphosphate, sodium salt) C10H13N2O14P3Na4 F.W. 570.1
