SuperG™ Plus Protein Preservative

SUPER G™ PLUS PROTEIN PRESERVATIVE

SuperG™ Plus Preservation Buffer delivers highly efficient blocking of non-specific protein binding on polymer films, with additional components optimized for long-term protein preservation.  This formulation improves assay performance for various proteins stored for extended periods after immobilization on polymer films.

Storage was under accelerated conditions at 38°C for up to 35 days equivalent to 1 year storage at 4°C. Controls were assayed immediately after preservation incubations. Assays were performed with individual anti-antigen antibodies and detected by fluorescence at 532nm (N=4 arrays).
Improved detection of Printed Antigenic Determinants with Optimized Preservation Reagents. Storage was under accelerated conditions at 38°C for up to 35 days equivalent to 1 year storage at 4°C. Controls were assayed immediately after preservation incubation. Assays were performed with individual anti-antigen antibodies and detected by fluorescence at 532 nm (N=4 arrays).

In the above example cytokine antigenicity was monitored over time, with  and without SUPER G™ PLUS PROTEIN PRESERVATIVE. Without effective preservation 75% of printed cytokines lost antigenicity in less than 200 days. With SUPER GPLUS 100 % of antigenicity was retained over the course of 1 year.

Applications

  • RPPA- reverse phase protein microarrays
  • Laser microdissection- RRPA
  • Antigen-capture assay
  • Antibody capture assay
  • Biomarker Discovery and Validation
  • Nanotoxicology
  • Serological Assay
  • Immunogen Discovery
