Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-HLA-DR antibody [EPR3692] - BSA and Azide free (AB209968)

This data was developed using ab92511 the same antibody clone in a different buffer formulation.

Immunohistochemical analysis of formalin fixed paraffin embedded human tonsil labelling HLA-DR with ab92511 at a concentration of 0.5µg/ml. The immunostaining was performed on a Ventana DISCOVERY ULTRA (Roche Tissue Diagnostics) instrument with a OptiView DAB IHC Detection Kit. Heat mediated antigen retrieval was performed with DISCOVERY cell conditioning solution (CC1) 100°C, pH8.5 for 32 mins. ab209968 Anti-HLA-DR antibody [EPR3692] was incubated for 16 mins at 37°C. Sections were counterstained with Hematoxylin II. Image inset shows absence of staining in secondary antibody only control.

Customers are encouraged to optimise antigen retrieval conditions, antibody concentration, incubation times and temperature for best results in their own IHC assay workflow (automated and manual).

Merged staining of anti-FOXP3 (ab215206; Cyan; TG540N), anti-PD1 (ab52587; Red; TG700N), anti-CD163 (ab182422; Brown; TG650N), anti-HLA-DR (ab92511; Yellow; TG570N), anti-CD4 (ab133616; Violet; TG620N), anti-CD8 alpha (ab101500; Purple; TG540S), anti-CD20 (ab9475; Grey; TG660S), anti-CD68 (ab192847; Green; TG520N), anti-Cytokeratin 19 (ab52625; Light blue; TG440N). TG470SN (dark blue) was used as a nuclear counter stain. The inset image shows the separate CD68 signal.

The section was incubated in nine rounds of staining; in the order of ab215206 (1/100 dilution), ab52587 (1/200 dilution), ab182422 (1/300 dilution), ab92511 (1/200 dilution), ab133616 (1/600 dilution), ab101500 (1/300 dilution), ab9475 (1/100 dilution), ab192847 (1/300 dilution), ab52625 (1/400 dilution); each using a separate fluorescent tyramide signal amplification system.

Sodium citrate antigen retrieval (pH6.0) was used in between rounds of tyramide signal amplification to remove the antibody from the previous round, to avoid any cross-reactivity.

Image acquisition was performed with TissueFAXS Spectra (TissueGnostics).

We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody. Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.
