Description

Technical Field

[0001] The utility model relates to the technical field of storage of penicillinase preparations, in particular to a storage device for extending the shelf life of penicillinase preparations. Background Art

[0002] Penicillinase, also known as β-lactamase, can hydrolyze β-lactam antibiotics. It uses genetic recombination technology to construct a high-efficiency expression strain of β-lactamase, and obtains recombinant β-lactamase (TEM1) through chromatography technology. It has the characteristics of high purity, high activity, and strong specificity. In order to ensure the shelf life of penicillinase, penicillinase needs to be stored in a low-temperature location to avoid unstable changes in penicillinase. For example, a Chinese patent discloses "A storage device for extending the shelf life of penicillinase preparations", and its application number is: "202120881003.6". It uses low-temperature gas to flow around the penicillinase preparation, effectively ensuring the stability of the penicillinase preparation. By changing the temperature of the storage environment of the penicillinase preparation, the shelf life of the penicillinase preparation can be effectively extended. However, the device is too large and inconvenient to move, and there are too many placement openings on each storage plate, which may affect other preparations when taking them out.
