Over few past decades SDT received several inquiries on PolyStreptavidin. Regretfully, we did not appreciate this as an
incentive for the new product development. At that time we did actually not recognize utility and potential of this product. Nonetheless now,
though belatedly, we offer a new Giant Premium PolyStreptavidin, #GPPSA. Originally made by SDT, expert in
fine protein polymerization and manufacturer of high performance polymeric detection conjugates for US/HS ImmunoAssays and NAT,
GPPSA is a highly robust and sustained product
available now for enhancing sensitivity in ICT/LFA, ELISA/ELONA, SPMP based CLIA, multiplex microchip and
other (Immuno)Assay tests and NAT.
