Abstract

The invention discloses a separator for an extracellular secretion body. The separator comprises an operation box, an operation chamber is formed in the operation box, a base is fixedly arranged on the bottom wall of the operation chamber, a supporting column is fixedly connected to the upper side of the base, and an axis sphere is fixedly connected to the upper end face of the supporting column; and through cooperating of a power motor and a rotating plate, when an inner centrifugal barrel rotates at a low speed, oscillation is continuously generated, secretory bodies are caused to oscillate, rapid separation of the secretory bodies is promoted, the separation efficiency is improved, and impurities adsorbed on the inner wall of the separation chamber are removed when the secretory bodies are separated through cooperating of a power shaft and a sliding block. The device is simple in structure and convenient to operate, excessive loss of secretory bodies is avoided, the separation effect is improved, a three-way ball valve is matched with a filtering membrane, separated liquid obtained through screening is subjected to secondary separation, waste is avoided, meanwhile, the separated liquid can be rapidly and stably discharged, and efficiency is improved.

Description

technical field [0001] The invention relates to the related field of secretion body separation, in particular to an extracellular secretion body separation instrument. Background technique [0002] Exosomes refer to extracellular vesicles that are transported by intracellular vesicles and discharged from the multivesicular body to the outside of the cell with a diameter of about 30-100 nm in the outer separation cylinder. Among them, differential centrifugation and ultrafiltration membrane filtration are the The most common exosome technique these days. [0003] However, when the existing secretion body separation equipment is used to separate the secretion body, multiple centrifugation is required, and the centrifugate is taken to screen out cells and apoptotic debris. And the sieved liquid is not subjected to secondary separation. Contents of the invention [0004] The purpose of the present invention is to address the above-mentioned problems existing in the prior art...
