We will launch the following new products in May 2025. ● Pesticide Mixed Standard Solution (2 items) This product is a mixed standard solution that corresponds to the "Simultaneous Testing Method for Pesticides, etc. by LC/MS 1 (Agricultural Products) (Appendix 1)." ● Reagents for HPLC We will sell a more user-friendly set of high-purity TFA for HPLC, consisting of 5 bottles of 5mL each. ● Standard Products for Food Analysis (6 items) We will newly sell six food-derived allergen extracts produced by Saika Technical Research Institute. ● Food Allergen Testing Kit We will newly sell the measurement item "Cashew Nut" from the Morinaga Bio Science Research Institute's food allergen testing kit, the NanoTrap Pro2 series. ● Simple Analysis Kit This product has been co-developed with Ajinomoto and allows for the easy measurement of the umami component glutamic acid through simple operations. ● Reagents for Nucleic Acid Synthesis (2 items) The newly sold capping reagents are low moisture guaranteed products that utilize our dehydration technology. ● Growth Factor Substitute Peptides (2 items) Growth factor substitute peptides are expected to demonstrate physiological activity equal to or greater than the existing recombinant protein "KGF (Keratinocyte Growth Factor)" and are anticipated to be used in the proliferation and differentiation of various epithelial cells, such as the epidermis.

We will launch the following new products in April 2025. ● General-purpose reagents (3 items) We are reviewing the packaging capacities and consolidating general-purpose reagents of special grade, deer special grade, and deer first grade standards. Accordingly, we are sequentially informing you of products that will be discontinued as stock runs out, and we will sell new capacities of standard products that are not subject to consolidation as alternatives to the discontinued items. ● High-purity solvent Primepure series (1 item) In the Primepure series, we will newly sell 3L packaging of acetonitrile. The "Primepure" series guarantees the highest purity specifications among commercially available reagents, exceeding existing specifications that are guaranteed by JIS special grade standards and by application. ● Ionic liquids (1 item) We will newly sell DEMEBF4 as our product from the ionic liquids that were sold under a joint label with Nisshinbo Holdings Inc. Ionic liquids are utilized in a wide range of fields such as separation, extraction, reaction solvents, electrochemical devices, tribology, vacuum technology, and bio-related applications, and are expected to be the next-generation solvent.

We will launch the following new products in March 2025. ● Reagents for LC/MS (2 items) In LC/MS analysis, volatile salts such as ammonium acetate and ammonium formate are commonly used as buffer solutions for pH adjustment of the mobile phase. These buffer solutions are also included in analytical methods for pesticide residue analysis in food and official methods such as the Waterworks Law. The newly sold "1 mol/L ammonium acetate solution" and "1 mol/L ammonium formate solution" guarantee "LC/MS testing compatibility," "metal guarantee," and "PFAS testing compatibility," in addition to the existing product guarantees, and implement stricter quality control than products for high-performance liquid chromatography. ● General-purpose reagents We will newly sell the "Sikajenius Vancomycin Resistance Gene Real-Time PCR Detection Kit." This kit uses a 4-plex real-time PCR to simultaneously detect the vanA, vanB, and vanC vancomycin resistance genes, as well as an internal control (IC) to check for PCR inhibition.
