In the field of life sciences, there is a demand for optical manipulation techniques that achieve high temporal and spatial resolution and allow for precise control that is difficult to achieve with drug administration, as a means of functional analysis of genes and the creation of disease models. This product is a light-inducible Cre recombinase (Photoactivatable Cre; PA-Cre) that combines Cre recombinase with the light-switchable protein Magnet System. By using this product, it becomes possible to control the function of genes in a time- and space-specific manner through light stimulation.

The "QIAxcel Connect" is a capillary electrophoresis device from QIAGEN that serves as an alternative to DNA/RNA gel analysis. It allows for safe and easy analysis using ready-to-use gel cartridges.

"SCOPE 21" is a desktop imaging device manufactured by OPTIMA Corporation. It comes with a variety of accessories, including a digital camera (requires an SDHC card) and filters for different staining solutions. Additionally, the digital camera is pre-configured for gel imaging.

CBB staining (Coomassie Brilliant Blue staining) is commonly used for protein staining after electrophoresis, but when preparing CBB staining solution in-house, it can be time-consuming due to the need for prolonged dissolution and filtration. Additionally, skipping the filtration step can lead to aggregated particles, causing uneven staining and reducing staining and decolorization efficiency, which takes more time. Kanto Chemical has improved the traditional CBB staining solution, offering a pre-prepared staining solution that enhances detection sensitivity and increases staining and decolorization speed. A two-component type that is resistant to changes over time and allows for MS analysis after decolorization → Rapid CBB KANTO A ready-to-use type that improves speed, sensitivity, and safety → Rapid CBB KANTO 3S *For more details, please refer to the catalog or feel free to contact us.

【Features】 ■High Quality The raw materials for Hi-QRAS Gel use carefully selected high-purity products, particularly for the main raw material, acrylamide monomer, which is crucial for separation performance, ultra-high purity needle-like crystals are used. ■High Resolution Hi-QRAS Gel has achieved unprecedented high separation capability through unique know-how accumulated over many years of precast gel manufacturing and research. ■High Precision Hi-QRAS Gel is manufactured in an environment where the optimal conditions for polymerization are strictly controlled and maintained.

Mycoplasma spp. is a type of true bacteria known to cause various diseases such as pneumonia, otitis media, arthritis, and mastitis in production animals like cattle. In this third seminar, titled "Clinical Aspects of Bovine Mycoplasma Infection," we will hear presentations on insights and responses from the clinical field.

Antibody drugs, which are representative biopharmaceuticals, are glycoproteins with attached sugar chains, and it is known that the type of sugar chain affects their biological activity and function. At the Glycoengineering Institute, we prepare sugar chains with determined composition, binding positions, and binding patterns as "standard sugar chains" for use in sugar chain analysis. Recently, the company has added a lineup of standard sugar chains that are optimal for antibody analysis. These are sugar chains highlighted in the guidance for quality evaluation of antibody drugs, "3.3.1.3 Sugar Chains" (December 14, 2012, Pharmaceutical and Food Safety Bureau Notification No. 1214). Furthermore, you can select and purchase only the necessary standard sugar chains according to your needs. We also offer sugar chain analysis services utilizing these standard sugar chains, so please feel free to consult with us.
