Provided in the present invention are a method for constructing a nucleic acid single-stranded cyclic library and reagents thereof. The method comprises the steps of using a transposase embedding complex to randomly break nucleic acids and connect a first linker; connecting a second linker at a gap; performing a first PCR reaction, wherein the 5' end of one of the primers has a first affinity tag, resulting in a product with two ends connected to different linker sequences; binding the product to a solid vector having a second affinity tag; degenerating and separating single strands having no affinity tag; and cyclizing the single strands.
摘要:
The synthesis of arrays of DNA probe sequences, polypeptides and the like is carried out using a patterning process on an active surface of a substrate (12). An image is projected onto the active surface (15) utilizing an image former (11) that includes a light source that provides light to a micromirror device (35) comprising an array of electronically addressable micromirrors (36). The substrate (12) is activated in a defined pattern and bases are coupled at the activated sites, with further repeats until the elements of a two-dimensional array on the substrate have an appropriate base bound thereto. The micromirror array (35) can be controlled in conjunction with a DNA synthesizer to control the sequencing of images presented by the micromirror array (35) in coordination with the reagents provided to the substrate (12).
摘要:
The invention refers to a modular continuous flow device for automated chemical multistep synthesis under continuous flow conditions. The device comprises a plurality of different types of continuous flow modules and a valve assembly for connecting the continuous flow modules to each other in a parallel or radial manner. This arrangement allows conducting convergent chemical reaction sequences by pre-synthesizing and intermediately storing or simultaneously synthesizing at least one intermediate product which is needed in the main synthetic reaction sequence in order to obtain the final product.
