摘要:
An object of the present disclosure is to provide an injector in which at least when a solution containing a biomolecule is injected into an injection target, a rate of the biomolecule that functions in the injection target is large. The object is achieved by an injector configured to inject a solution containing a biomolecule and a gas that is predetermined into an injection target without using an injection needle, the injector including a storage portion configured to store the solution containing the biomolecule and the gas, a nozzle portion communicating with the storage portion, the nozzle portion including an ejection port configured to eject the solution containing the biomolecule and the gas toward the injection target, and a pressurization portion configured to pressurize the solution containing the biomolecule and the gas that are stored in the storage portion during an operation and to eject the solution containing the biomolecule and the gas from the ejection port toward the injection target.

The disclosure provides a method for breeding Carassius auratus strains without intermuscular bones, which relates to aquaculture breeding method. In order to eliminate intermuscular bones in Carassius auratus, a method for breeding strains of Carassius auratus with fewer intermuscular bones or without intermuscular bones by knocking out the bmp6 gene is proposed by the present disclosure. Breeding method: designing knockout target sites for the two copies of the bmp6, bmp6a and bmp6b, in the Carassius auratus genome, and then obtaining F2 generation individuals from a homozygous line with bmp6a and bmp6b double gene mutation through two rounds of gene knockout and screening, and then propagating by using the F2 generation individuals from the homozygous line with bmp6a and bmp6b double gene mutation to form a new Carassius auratus strain with intermuscular bone-deficient. Strains of Carassius auratus with less than 20 intermuscular bones and without intermuscular bones are obtained by the method of the present disclosure.
摘要:
A method and device for preferentially delivering a compound such as an antigen to the cytosol of an immune cell. The method comprises passing a cell suspension comprising the target immune cell through a microfluidic device and contacting the suspension with the compound(s) or payload to be delivered.

摘要:
The invention relates to those apparatus that include a disposable microsyringe, whose tubular body is attached by its rear end into the front starting point of a longitudinal void of an intermediate housing, locating in said longitudinal void a moving head movable upon an axis and, which is connected to the rear end of the syringe plunger. It is characterised in that the moving head (9) is also connected, by means of a longitudinal rod (12), to a moving carriage (13) movable upon an axis along the same direction as the moving head (9), and being said moving carriage (13) guided within an elongated tube (8) connected to at the rear end of the intermediate housing (7), as a continuation thereof, incorporating to said elongated tube (8) a motor element, whose actuation drives the plunger (10) by means of a moving head (9), a longitudinal rod (12) and a moving carriage (13).
