Pure sericin is a high-purity protein derived from silk cocoons. In a heat stress test at 60°C for 1 hour, while the industry-standard BSA significantly loses activity, it has been confirmed that the addition of pure sericin maintains almost all of its activity (Patent No. 5022673). It can be used as an additive to improve the storage stability of diagnostic reagents and enzyme preparations. *The detailed usage method, such as whether it is used alone or in combination with other components, is currently under review, so please contact us first. It is free from mammalian-derived components and can be supplied stably with minimal lot variation.

Pure sericin is a high-purity protein derived from silk cocoons. By adding approximately 0.01 to 0.5 wt% to your complete culture medium, it can be used as a supporting factor (booster) to support cell proliferation and viability. Since it is insufficient as a nutrient on its own, it is intended to be used in conjunction with other medium components. In the culture of hybridoma cells, we have confirmed cell proliferation and antibody production enhancement effects similar to those of FBS (fetal bovine serum) with significant lot variability (in collaboration with Fukui University). It is free from mammalian-derived components, allowing for stable supply with minimal lot variation.

Pure sericin is a high-purity protein derived from silk cocoons. It can be used as an additive (raw material) to be mixed into existing cryopreservation solutions, rather than being a cryopreservation solution itself. In cryopreservation tests using the vitrification method for human iPS cells, it has been confirmed to significantly improve cell survival rates after thawing as a natural, low-toxicity protective material that can replace chemical cryoprotectants such as DMSO (Patent No. 6333513). Since it does not contain components derived from mammals, it is a material that easily meets safety requirements in the field of regenerative medicine. Consistent production at our domestic factory allows for stable supply with minimal lot variation.

Pure sericin is a high-purity protein derived from silk cocoons. In both ELISA and immunochromatography evaluation systems, it has demonstrated a non-specific adsorption inhibition rate equal to or greater than the industry standard BSA (bovine serum albumin) (as described in Patent No. 4618648), and can be used as a standalone blocking agent in the blocking step. Please dissolve it in a buffer solution for use. Depending on the formulations and conditions of various companies, it can also be used in combination with other components. It contributes to formulations that do not use mammalian-derived ingredients. Consistent production at our domestic factory allows for stable supply with minimal lot variation. There is a track record of adoption by diagnostic reagent manufacturers.

The "Head Fixed (Line) Type" fixes the printer head during decoration, and an image is formed in one pass as the substrate is transported. It is suitable for high-speed printing for mass production and low-cost printing. However, the equipment cost is high, and the print quality is inferior to that of head scanning types. High-speed and mass printing is possible. 【Features】 ■ During decoration, the printer head is fixed, and an image is formed in one pass as the substrate is transported. ■ High-speed and mass printing is possible. ■ Advantages: Suitable for mass printing and low-cost printing with fast printing speeds (10m↑/min). ■ Disadvantages: High equipment cost and print quality inferior to head scanning types. *For more details, please refer to the PDF materials or feel free to contact us.

The "Head Scan (Serial) Type" moves the printer head vertically in relation to the material's direction of progress during decoration, resulting in the formation of an image after several passes. It is suitable for high-definition printing (photo quality, fine lines). The printing speed is slow (up to 100 m²/hour), and alignment of the substrate is necessary. It is possible to print with high accuracy and is suitable for high-definition printing. 【Features】 - During decoration, the printer head moves vertically in relation to the material's direction of progress. - An image is formed as a result of several passes. - It is possible to print with high accuracy and is suitable for high-definition printing. - Advantages: Suitable for high-definition printing (photo quality, fine lines). - Disadvantages: Slow printing speed (up to 100 m²/hour) and requires substrate alignment. *For more details, please refer to the PDF document or feel free to contact us.
