Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Filaggrin antibody [EPR21892] - BSA and Azide free (AB231821)

This data was developed using ab221155, the same antibody clone in a different buffer formulation.

Immunohistochemical analysis of paraffin-embedded human skin tissue labeling Filaggrin with ab221155 at 1/1000 dilution followed by a Ready to use Rabbit specific IHC polymer detection kit (ab209101).

Positive staining on human skin.

The primary antibody was incubated for 30 mins at room temperature.

The immunostaining was performed on a Leica Biosystems BOND^® RX instrument

Counterstained with Hematoxylin.

Heat mediated antigen retrieval was performed with Tris-EDTA buffer (pH 9.0, Epitope Retrieval Solution2) for 20 mins.

Multiplex immunohistochemistry - Anti-Filaggrin antibody [EPR21892] - BSA and Azide free (AB231821)

This data was developed using ab221155, the same antibody clone in a different buffer formulation.

Multiplex immunohistochemistry analysis of formalin/PFA-fixed paraffin-embedded human skin staining Collagen VII with ab309143 at a 1/100 dilution, ab307969 anti-Aquaporin 3 used at 1/5000 dilution and ab221155 anti-FLG used at a 1/1000 dilution.

Panel A : merged staining of anti-Collagen VII (green; Opal™520), anti-Aquaporin 3 (magenta; Opal™690) and anti-FLG (gray; Opal™570) on human skin.

Panel B : anti-Collagen VII staining basement membrane in human skin.

Panel C : anti-Aquaporin 3 staining squamous epithelium in human skin.

Panel D : anti-FLG staining maturing squamous cells in human skin.

Nuclear DNA was labeled with DAPI (shown in blue).

The section was incubated in three rounds of staining : in the order of ab309143, ab307969 and ab221155 for 30 mins at room temperature. Each round was followed by a separate fluorescent tyramide signal amplification system.

The immunostaining was performed on a Leica Biosystems BOND® RX instrument with an Opal™ 4-color kit. Image acquisition was performed with Leica SP8 confocal microscope.

Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins.

Multiplex immunohistochemistry - Anti-Filaggrin antibody [EPR21892] - BSA and Azide free (AB231821)

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of Human skin tissue labelling Aquaporin 3 with ab307969 at 1/5000 dilution (0.094 µg/mL) (B), Loricrin with ab176322 at 1/3000 dilution (0.031 μg/ml) (C) and Filaggrin with ab221155 at 1/2000 dilution (0.523 μg/ml) (D). Opal Polymer HRP Ms + Rb was used as a secondary antibody, and DAPI was used for a nuclear counter stain. Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins. Panel A : merged staining of anti-Aquaporin 3 (magenta; Opal™690), anti-Loricrin (green; Opal™520) and anti-Filaggrin (red; Opal™570) on human skin. Panel B : anti-Aquaporin 3 stained on keratinocytes from the stratum basale to the stratum granulosum of the epidermis. Panel C : anti-Loricrin stained on stratum corneum. Panel D : anti-Filaggrin stained on the granular to stratum corneum transition. The section was incubated in three rounds of staining : in the order of ab307969, ab176322, and ab221155 for 30 mins at room temperature. Each round was followed by a separate fluorescent tyramide signal amplification system. The immunostaining was performed on a Leica Biosystems BOND® RX instrument with an Opal™ 4-color kit.
