Cell culture plate fixture structure

Abstract

The invention provides a cell culture plate fixture structure which can conveniently and quickly press and fix a cell culture plate on a shaking table so as to determine the airtightness of connection between a plate cover of the cell culture plate and a culture plate main body. The cell culture plate fixture structure comprises a bottom plate, wherein a groove matched with the cell culture plate is formed in the bottom plate; support frames are symmetrically arranged on the two sides of the groove; rotating shafts are arranged at the upper ends of the support frames; a pressure rod comprises a pressure rod arm and a connecting part arranged at one end of the pressure rod arm, the connecting part is connected with the rotating shaft in a penetrating way, a torsion spring is arranged on the rotating shaft in a sleeving way, two spring legs of the torsion spring respectively lean against the lower end surface of the pressure rod arm and the upper end surface of the support frame, and a pressure strip is arranged on the other side of the connecting part opposite to the pressure rod arm and is arranged above the groove in parallel.

Description

technical field [0001] The invention relates to the technical field of cell culture devices, in particular to a fixing device for deep and shallow hole cell culture plates for aerobic cell culture, in particular to the structure of a cell culture plate fixture. Background technique [0002] With the development of molecular biology, the heterologous protein expression technology has gradually matured and been widely used. The expression of foreign proteins requires the selection of suitable expression hosts and expression elements, which requires the construction of a huge expression library, from which a better expression kit can be selected. The cell culture plate can use less culture medium for high-throughput cell culture and screening of strains, cell lines and expression libraries, and has the characteristics of fast, high-throughput, and cost-saving. [0003] In order to avoid bacterial contamination or cross-contamination between plate wells, the existing cell cultu...

AI Technical Summary

Problems solved by technology

[0003] In order to avoid bacterial contamination or cross-contamination between plate wells, the existing cell culture plates need to be sealed. There are currently two ways to seal the plate mouth, one is latex pad sealing type, and the other is "sandwich" Type plate cover seal, latex pad can not carry out gas exchange when in use, and the sealing is poor, and "sandwich" type plate cover can carry out gas exchange well, avoid cross-contamination

However, the seal cannot be guaranteed when the plate cover is used in combination with a deep well plate, and a specific culture shaker is required
