Protokoll

Primärantikörper: ABIN735608

Sekundärantikörper: HRP-conjugated goat anti-rabbit antibody (medac diagnostics, DPVR-110HRP, Lot 101122)

Full Protocol:

• Dewax and rehydrate tissue sections on glass slides in a descending xylene and graded alcohol series:
• • xylene 2x for 5 min.
  • 100 % (v/v) ethanol 2x for 5 min.
  • 96 % (v/v) ethanol 2x for 5 min.
  • 70 % (v/v) ethanol 2x for 5 min.
• Wash slides 2x 5 min with ddH2O.
• Cook slides for 30 min at 95 °C in citrate buffer pH 6.
• Wash slides 2x 3 min with ddH2O.
• Incubate slides in 0.3 % (v/v) H2O2 in PBS for 15 min to quench endogenous peroxidase.
• Wash slides 3x 3 min in 1X PBS.
• Block slides in 10 % goat serum in PBS for 30 min at RT.
• Incubate slides with primary rabbit anti-PD-1 antibody (antibodies-online, ABIN735608, lot BC04411027) diluted 1:250 and 1:500 in 10 % goat serum in PBS ON at 4 °C in a humidified chamber.
• Wash slides 3x 3 min in 1X PBS.
• Incubate slides with secondary HRP-conjugated goat anti-rabbit antibody (medac diagnostics, DPVR-110HRP, Lot 101122) ready-to-use in 10 % goat serum in PBS for 30 min at RT in a humidified chamber.
• Wash slides 3x 3 min in 1X PBS.
• HRP development.
• Counterstain slides with hematoxylin solution (Carl Roth, T865.2).
• Wash slides for 15 min under running tap water.
• Dehydrate sections in an ascending alcohol-xylene series:
• • 70% ethanol 2x for 10 sec.
  • 96% ethanol 2x for 10 sec.
  • 100% ethanol 2x for 10 sec.
  • xylene 2x for 10 sec.
• Mount sections with Entellan new mounting medium (Sigma-Aldrich, 1008690500).
• Dry sections.
• Image acquisition on an Aperio CS2 Digital Pathology Slide Scanner (Leica), Magnification 40x.

Anmerkungen:

• Staining with ABIN735608 the signal at 1:250 and 1:500 antibody dilution in human tonsil was sharp and localized in the cells within the germinal zone (as expected).

• ABIN735608 reactivity was also tested in mouse samples. However, in mouse spleen, the signal was almost absent and very weak at Ab dilution 1:250 and 1:500. No signal was detected in mouse pancreas. Even increasing the Ab concentration to 1:150 dilution, in mouse tumor tissue, ABIN735608 detected a very weak, unclear, and sporadic signal. The quality of the signal does not allow the possibility of background staining to be excluded.
