Recombinant Anti-FOXP3 antibody [236A/E7] - BSA and Azide free (ab96048)

Fluorescence multiplex immunohistochemical analysis of Human breast cancer tissue (formalin-fixed paraffin-embedded section).

Merged staining of Anti-PD-L1 (ab251611; cyan; Opal™ 520), Anti-Granzyme B (ab219803; yellow; Opal™ 540), Anti-PD1 (ab251613; magenta; Opal™ 570), Anti-pan Cytokeratin (ab264485; red; Opal™ 620), Anti-EpCAM (ab225894; red; Opal™ 620), Anti-CD8 alpha (ab251596; green; Opal™ 650) and Anti-FOXP3 (ab96048; orange; Opal™ 690). EpCAM and pan-cytokeratin share the same dye and color. Dyes are pseudo-colored for better contrast of the markers.

The immunostaining was performed on a Leica Biosystems BOND^® MAX instrument with an Opal™ 6-Plex Detection Kit (NEL821001KT, Akoya Biosciences^®).

The section was incubated in six rounds of staining; sequentially for ab251611 (1/750 dilution), ab219803 (1/250 dilution), ab251613 (1/750 dilution), ab264485 (0.5 µg/ml), ab225894 (1/1250 dilution), ab251596 (1/1500 dilution) and ab96048 (10 µg/ml); each using a separate fluorescent tyramide signal amplification system. EDTA based antigen retrieval (Leica Biosystems BOND^® Epitope Retrieval Solution 2, pH 9.0, 20 minutes) was used in between rounds of tyramide signal amplification to remove the antibody from the previous round, to avoid any cross-reactivity. DAPI (dark blue) was used as a nuclear counter stain.
Microscopy and pseudocoloring of individual Opal™ dyes was performed using a Vectra 3 Imaging System (Akoya Biosciences^®).

This data was developed using ab20034, the same antibody clone in a different buffer formulation.

ab20034 detects Human FOXP3 protein at ~50 kDa in HEK293T cells overexpressing the protein. It also detects FOXP3 in Human tonsil tissue lysate, however this band is significantly weaker in endogenous conditions. Upon higher exposure, weak bands can also be observed in HEK293T cell lysate.

This blot was produced using a 4-12% Bis-Tris gel under the MOPS buffer system. The gel was run at 200V for 60 minutes before being transferred onto a nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour before being incubated with Anti-FOXP3 antibody [236A/E7] (ab20034; 5 microgram per mL) overnight at 4°C. Antibody binding was detected using infrared labelled goat anti-mouse (green; 1:10000) for 1 hour at room temperature before imaging.
