NEXTERION® Slide P - The slide of choice for Antibody Microarrays

  1. 1. SCHOTT NEXTERION ® NEXTERION Slide P - The slide of choice for antibody microarrays
  2. 2. NEXTERION ® Slide P Coating Structure and Probe Attachment Principle Proprietary polymer, ensuring very low non-specific binding Glass support NHS-ester C O O N O O Attached to polymer
  3. 3. NEXTERION ® Slide P – Spot morphology Excellent spot morphology on NEXTERION Spot PB Data obtained using a contact printer 4µg/ml RaG in PPB 20µg/ml RaG in PPB Marker spots 100µg/ml RaG in PPB 500µg/ml RaG in PPB 1000µg/ml RaG in PPB 1500µg/ml RaG in PPB 1800µg/ml RaG in PPB P rotein P rint B uffer only 500µg/ml RaG in PP 100µg/ml RaG in PP Marker spots Slide P (30 µg/ml labeled Goat IgG)
  4. 4. NEXTERION ® Slide P – Binding capacity High binding capacity on Slide P – up to 1mg/ml probe concentration Hyb concentration in µg/ml IgG from Goat serum (probe) (target)
  5. 5. NEXTERION ® Slide P – Background Extremely low backgrounds on Slide P shown with various targets H P E AL
  6. 6. NEXTERION ® Slide P – Signal to Bkg ratios Superior S/B ratios for slide P
  7. 7. NEXTERION ® Slide P – Signal to Bkg ratios Superior S/B ratios for slide P
  8. 8. Spot – Diameter with Next spot PB <ul><li>Spot morphology was good on all substrates </li></ul><ul><li>But only Nexterion NC-W/D and the FAST slide gave acceptable </li></ul><ul><li>spot sizes for higher concentrations of detergents in the print buffer </li></ul>

  10. 10. Referenced KTH Paper Rebecca Rimini, Jochen M. Schwenk, Mårten Sundberg, Ronald Sjöberg, Daniel Klevebring, Marcus Gry, Mathias Uhlén and Peter Nilsson Validation of serum protein profiles by a dual antibody array approach Journal of Proteomics, Volume 73, Issue 2, 1 December 2009, Pages 252-266 doi:10.1016/j.jprot.2009.09.009
  11. 11. KTH results – Slide P had a 100 times lower background than Corning Epoxide 1:500 1:2000 1:8000 Biotin-labeled sera Epoxy Corning Slide P Schott
  12. 12. KTH Print buffer contained Trehalose & Pluronic F127 data obtained with non contact printer Nano-Plotter 2.0/E 5% 5% APOH APOA4 Trehalose in the plate Trehalose before printing
  13. 13. Assay conditions not described
  14. 14. Storage at 4°C for 4 months (KTH data)
  15. 15. Effect of environmental conditions on NEXTERION Slide P performance
  16. 16. Is NHS hydrolysis an issue during long print runs? Acceptable slide performance after 2 days exposure to 30 – 70 % relative humidity prior to printing
  17. 17. Conclusion <ul><li>NEXTERION Slide P has the best S/N ratios of all the SCHOTT slide coatings for antibody arrays </li></ul><ul><li>Very low non specific binding, and probably lowest of any commercially available microarray slide on the market </li></ul>
