Artificial gene synthesis, or simply gene synthesis, refers to a group of methods that are used in synthetic biology to construct and assemble genes from nucleotides de novo. Unlike DNA synthesis in living cells, artificial gene synthesis does not require template DNA, allowing virtually any DNA sequence to be synthesized in the laboratory.
Cytocentrifuge. A cytocentrifuge, sometimes referred to as a cytospin, [1] is a specialized centrifuge used to concentrate cells in fluid specimens onto a microscope slide so that they can be stained and examined. [2] Cytocentrifuges are used in various areas of the clinical laboratory, such as cytopathology, hematology and microbiology, as ...
Laboratory centrifuge. Centrifugation is a mechanical process which involves the use of the centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity and rotor speed. [ 1] The denser components of the mixture migrate away from the axis of the centrifuge, while the less dense components of ...
Iron rings used in a laboratory. An iron ring or ring clamp is an item of laboratory equipment which comprises a conjoined metal ring and radially-extending rod. [1] In some cases, the rod terminates in a screw clamp for attachment to a retort stand or other support; in others, the rod may be attached to a stand by means of a laboratory clamp holder. [2]
Laboratory centrifuge. A laboratory centrifuge is a piece of laboratory equipment, driven by a motor, which spins liquid samples at high speed. There are various types of centrifuges, depending on the size and the sample capacity. [ 1] Like all other centrifuges, laboratory centrifuges work by the sedimentation principle, where the centripetal ...
A laminar flow cabinet or tissue culture hood is a partially enclosed bench work surface designed to prevent contamination of biological samples, semiconductor wafers, or any particle sensitive materials. Air is drawn through a HEPA filter and blown in a very smooth laminar flow in a narrow vertical curtain, separating the interior of the ...
Assembly theory conceptualizes objects not as point particles, but as entities defined by their possible formation histories. [ 5] This allows objects to show evidence of selection, within well-defined boundaries of individuals or selected units. [ 5] Combinatorial objects are important in chemistry, biology and technology, in which most ...
Air displacement pipette. Piston-driven air displacement pipettes are a type of micropipette, which are tools to handle volumes of liquid in the microliter scale. They are more commonly used in biology and biochemistry, and less commonly in chemistry; the equipment is susceptible to damage from many organic solvents.
