Abstract: The present invention relates to improved processes for production of closed linear deoxyribonucleic acid (DNA), in particular cell-free enzymatic production of closed linear DNA molecules, preferable using a closed linear DNA as a template for DNA synthesis. The invention further relates to a novel closed linear DNA species, suitable for use as a template in the improved processes for production of closed linear DNA. Further, the invention pertains to the intermediate products of the processes, since this enables the production of larger quantities of closed linear DNA from the template than with methods known in the art.

Abstract: The present invention relates to an improved process for synthesis of deoxyribonucleic acid (DNA), in particular cell-free enzymatic synthesis of DNA, preferably on a large or industrial scale, with an improved yield and/or with an improved efficiency. The invention requires the use of nucleotide complexes wherein the nucleotide is associated with a mixture of divalent and monovalent cations. Preferably, the divalent cation may be magnesium or manganese.

Abstract: The present invention relates to an improved process for synthesis of deoxyribonucleic acid (DNA), in particular cell-free enzymatic synthesis of DNA, preferably on a large scale, with an improved yield and/or with an improved efficiency. The species of cation present in the nucleotide salt as the counter-ion is critical to the yield, efficiency and fidelity of high yielding enzymatic DNA synthesis reaction. The processes herein use alternative cations as counter-ions for the ionic nucleotides, permitting the use of higher concentrations of nucleotides in DNA synthesis, and further allowing for more favourable reaction conditions to be used.

Abstract: The present invention relates to an improved process for synthesis of DNA, RNA, proteins and like molecules, in particular cell-free enzymatic synthesis of DNA, preferably in large scale. The present invention relates to the synthesis of DNA using strand-displacement replication and the addition of nucleotides to the reaction mixture is controlled, thus controlling yield. The reaction mixture contains a starting amount of nucleotides, polymerase and DNA template, to which further nucleotides are supplied in a controlled manner.

Abstract: A biochemical synthesis apparatus comprises a receptacle for containing a medium, and a support on which a microorganism can be placed. The support can be placed in contact with the medium, so as to allow access of the microorganism to the medium. The support with the microorganism can be removed from the medium, allowing the medium to be replaced. By this, the receptacle can firstly contain a growth medium, and secondly a secondary medium capable of causing the production by the microorganism of a potentially useful biochemical.
