This disclosure provides methods, systems, and compositions of matter for studying solvent accessibility and three-dimensional structure of biological molecules. A plasma can be used to generate marker radicals, which can interact with a biological molecule and mark the solvent-accessible portions of the biological molecule.

A method of rapidly producing a double-stranded target DNA is disclosed. The method includes the step of producing multiple single stranded primary DNA constructs having (a) partially overlapping and complementary internal regions that together define the target DNA, and (b) flanking regions on either side of the internal regions containing a PCR primer recognition site and a restriction enzyme recognition site. The primary DNA constructs are amplified to form a pool of double-stranded primary constructs, and a restriction enzyme is used to cleave off the flanking regions. The target double-stranded DNA is then assembled from the cleaved fragments. Hundreds of thousands of oligonucleotides can be synthesized and quickly and efficiently assembled into many different individual double-stranded DNA target sequences using this method.

Methods for rapid production of double-stranded target DNA

The synthesis of arrays of DNA probes sequences, polypeptides, and the like is carried out using a patterning process on an active surface of a substrate. An image is projected onto the active surface of the substrate utilizing reflective projection optics. The projection optics project a light image onto the active surface of the substrate to deprotect linker molecules thereon. A first level of bases may then be applied to the substrate, followed by development steps, and subsequent exposure of the substrate utilizing a different light image, with further repeats until the elements of a two dimensional array on the substrate surface have an appropriate base bound thereto.

A method is disclosed for the direct synthesis of double stranded DNA molecules of a variety of sizes and with any desired sequence. The DNA molecule to be synthesis is logically broken up into smaller overlapping DNA segments. A maskless microarray synthesizer is used to make a DNA microarray on a substrate in which each element or feature of the array is populated by DNA of a one of the overlapping DNA segments. The complement of each segment is also made in the microarray. The DNA segments are released from the substrate and held under conditions favoring hybridization of DNA, under which conditions the segments will hybridize to form duplexes. The duplexes are then separated using a DNA binding agent which binds to improperly formed DNA helixes to remove errors from the set of DNA molecules. The segments can then be hybridized to each other to assemble the larger target DNA sequence.

Method of error reduction in nucleic acid populations

The synthesis of arrays of DNA probes sequences, polypeptides, and the like is carried out using a patterning process on an active surface of a substrate. An image is projected onto the active surface of the substrate utilizing an image former that includes a light source that provides light to a micromirror device comprising an array of electronically addressable micromirrors, each of which can be selectively tilted between one of at least two positions. Projection optics receives the light reflected from the micromirrors along an optical axis and precisely images the micromirrors onto the active surface of the substrate, which may be used to activate the surface of the substrate. The first level of bases may then be applied to the substrate, followed by development steps, and subsequent exposure of the substrate utilizing a different pattern of micromirrors, with further repeats until the elements of a two dimensional array on the substrate surface have an appropriate base bound thereto. The micromirror array can be controlled in conjunction with a DNA synthesizer supplying appropriate reagents to a flow cell containing the active substrate to control the sequencing of images presented by the micromirror array in coordination of the reagents provided to the substrate.

Method and apparatus for synthesis of arrays of DNA probes

A method is described for the detection of a rare deletion mutant allele in a population of wild-type individuals. DNA samples from the individuals are subjected to a modified form of polymerase chain reaction (PCR) which favors the replication of truncated DNA strands over the synthesis of wild-type full length strands. The preferred way to bias the process toward the synthesis of truncated DNA strands is by limiting the extension step in the PCR reaction protocol. This process permits the convenient detection of a deletion mutant allele from a population of 1000 wild type individuals with the full length allele.
