We will hold a webinar titled "Proposal for Testing Methods Using Standard Material 'Food Allergen Extract' - Application to Cashew Nut Allergen Testing." This time, we are pleased to invite Ms. Eri Inagaki from the Saika Technical Research Institute, a public interest incorporated foundation, to give a lecture on the analysis method using the standard material developed by the foundation with LC-MS/MS. Additionally, we will introduce products related to food allergen testing from our company. We sincerely look forward to your participation. Date and Time: October 23, 2025 (Thursday) 13:00 - 13:50 Title: Proposal for Testing Methods Using Standard Material "Food Allergen Extract" - Application to Cashew Nut Allergen Testing Lecturer: Ms. Eri Inagaki, Saika Technical Research Institute, Public Interest Incorporated Foundation Registration: Please register using the participation application form at the URL below (this will take you to the seminar distribution company's page). Application Period: Until 13:00 on October 23, 2025 * Applications will be closed once the maximum number of participants is reached. * Applications from competitors will not be accepted. * Secondary distribution of the sent URL is prohibited.

We will launch the following products in October 2025. ● General-purpose reagents (5 items) We are reviewing the packaging capacities and consolidating general-purpose reagents of special grade, deer special grade, and deer grade 1 specifications. We will sell new capacities of specifications that are not targeted for consolidation as alternatives to discontinued items. ● Standard materials for environmental analysis (3 items) We will begin handling three standard materials manufactured by LGC Standards for compounds listed in the positive list. ● Shikajenius MRSA-related gene real-time PCR detection kit (1 item) This kit detects MRSA-related genes using a 4-plex real-time PCR. ● Rapid screening reagent for third-generation cephalosporin-resistant bacteria (1 item) This reagent is used to screen Enterobacteriaceae that show resistance to third-generation cephalosporin antibiotics. ● Standard bacterial strains for MALDI TOF-MS quality control (3 items) This product is a set of standard bacterial strains that can be used for quality control of the Bruker MALDI Biotyper. We have prepared sets tailored to specific fields.

We will be exhibiting at "BioJapan 2025." We would like to invite you to visit our booth. All of our staff are sincerely looking forward to your visit. ■ Booth Number: D-69 ■ Exhibitor Website https://biojapan2025.jcdbizmatch.jp/Lookup/jp/Member/u0?ke=%E9%96%A2%E6%9D%B1%E5%8C%96%E5%AD%A6&np=2&ob=1&ub=1 ■ Exhibition Content: Manufacturing services for cell culture media and preparation solutions, reagents related to regenerative medicine (such as the ciKIC series), reagents related to cell assays (such as the ad-MED Vitrogel series), etc.

We will launch the following new product in August 2025. ● Cell Culture Equipment ad-MED Vitrigel Series (1 item) We will newly sell the cell culture equipment "ad-MED Vitrigel Ex (24-well)" using a collagen Vitrigel Ex membrane with high permeability. The collagen Vitrigel membrane has a high-density collagen structure comparable to connective tissue in vivo. This product demonstrates high cell adhesion similar to the conventional ad-MED Vitrigel 2 while improving permeability, making it widely usable for research such as analyzing cell-to-cell interactions through co-culture of different cell types and constructing cell assay systems similar to regular cell culture inserts.

We will launch the following new products in June 2025. ● General-purpose reagents (1 item) We are reviewing the packaging capacities and consolidating products for general-purpose reagents in special grade, deer special grade, and deer grade 1 standards. We will sell new capacities of standard products that are not targeted for consolidation as alternatives to discontinued items. ● Organolithium compounds (2 items) Lithium amide reagents are primarily used as bases for deprotonation applications. Compared to alkyl lithium reagents, lithium amide reagents have lower nucleophilicity, which provides the advantage of suppressing nucleophilic addition of alkyl chains that can be problematic with alkyl lithium reagents. ● Chromagar medium 500 g packaging (2 items) Chromagar has decided to change the product capacity. As a result, we will discontinue some of the current packaging and introduce a new 500 g packaging. ● Precision control for microscopic examination (11 items) We will newly sell the "Microbiology Slide" series of precision controls for microscopic examination manufactured by Microbiologics. This product fixes microorganisms (bacteria, protozoa) on a glass slide and can be used as a precision control for microscopic examination from staining to observation.
