Contributing to cell safety!
Aseptic testing is generally required to be conducted using the final processed product as the test specimen, based on the aseptic testing method specified in the Japanese Pharmacopoeia General Test Method (4.06). This testing method requires a culture period of more than 14 days to obtain results. On the other hand, for specific cell processing products, it is desirable to obtain the results of the aseptic test before administration to the patient. However, due to the time required to obtain results from the pharmacopoeia-compliant aseptic test, it is often the case that test results are determined after administration. Additionally, for specific cell processing products, due to limitations such as the amount of specimen available and the time required for testing, it may not be possible to apply the aseptic testing method compliant with the pharmacopoeia. In such cases, consideration may be given to the "Rapid Microbial Testing Method" (as referenced in the 18th revision of the Japanese Pharmacopoeia). Our company has developed a rapid aseptic testing method using PCR that covers a wide range of microorganisms, including not only those listed in the pharmacopoeia but also environmental bacteria and human-derived bacteria, allowing for detection in a short time.

![A new biotin labeling agent that allows control over the introduction location and quantity [Saitama University]](https://image.mono.ipros.com/public/product/image/2001542086/IPROS11965949861184904705.png?w=280&h=280)
The key is the re-crosslinking of S-S bonds! A novel biotin labeling agent that stabilizes the structure and function of proteins.
Conventional biotin labeling randomly binds to the functional groups of proteins, making it difficult to control the number of biotins attached and their binding positions. Additionally, the cleaved S-S bonds for labeling do not re-bridge, leading to changes in the higher-order structure of the protein and a decrease in activity, which is a challenge. In this technology, biotin is introduced to the Br group of dibromo-pyridazine dione, and the re-bridging of S-S bonds occurs simultaneously with labeling. This stabilizes the higher-order structure of the protein and maintains its activity. The number of attached biotins can be selected as either one or two, and it can be used for controlling the orientation of proteins by utilizing the binding characteristics with streptavidin.
