Pure Sericin | Diagnostic reagent blocking agent BSA alternative antigen testing, etc.
Pure Sericin
BSA alternative. Demonstrated non-specific adsorption exclusion effect in both ELISA and immunochromatography using a blocking agent free of mammalian-derived components.
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.

Company information
Seiren Co., Ltd. is a comprehensive textile manufacturer founded over 130 years ago and listed on the Prime Market of the Tokyo Stock Exchange. Guided by our vision of "changing the world through dreams," we have built on core competencies accumulated over more than a century in the textile industry to develop high-value-added businesses that extend far beyond textiles, spanning digital manufacturing and life sciences. ■ Inkjet Solutions Business "VISCOTECS" is our proprietary digital production system that integrates planning, manufacturing, and sales into a single seamless process. It enables high-mix, low-volume, short-lead-time, and inventory-free production, realizing an environmentally friendly business model that delivers "what you want, when you want it, in the quantity you need." Our inkjet technology has been applied across a wide range of businesses, including: - Integrated inkjet manufacturing solutions that address diverse customer challenges through our own end-to-end inkjet production capabilities - High-precision industrial inkjet systems for fine printing and precision coating applications - Customized mass-production inkjet systems tailored to customer needs in non-textile fields ■ Pure Sericin (Biomaterial) Business "Pure Sericin" is a high-purity, multifunctional protein derived from silk cocoons and manufactured using our proprietary purification technology. Originally developed through decades of expertise in silk processing, this innovative biomaterial has found new applications in the life sciences field, where it is used as: - A blocking agent for ELISA and other immunoassays, demonstrating a non-specific adsorption inhibition rate comparable to or exceeding that of BSA (bovine serum albumin), while contributing to animal-free formulations - An additive for the cryopreservation of iPS cells and stem cells, offering a DMSO-free, low-toxicity alternative that supports higher post-thaw cell viability - A booster for cell culture media, added at low concentrations to support cell proliferation and viability, with growth-promoting effects comparable to FBS (fetal bovine serum) in hybridoma cell culture Free from mammalian-derived components, Pure Sericin is manufactured and supplied with consistent quality at our own domestic facility, and has already been adopted by manufacturers of in vitro diagnostic reagents. With decades of experience in stable, large-scale production, we are committed to being a reliable long-term partner for the life sciences industry.
