HECA-452_Pure_011812
Human peripheral blood lymphocytes were stained with purified CLA (clone HECA-452) (filled histogram) or rat IgM isotype control (open histogram), followed by biotinylated anti-rat IgM and Sav-PE.

    Human paraffin-embedded tonsil tissue slices were prepared with a standard protocol of deparaffinization and rehydration. Antigen retrieval was done with Citrate Buffered 1X (1.0M, pH 7.4) at 95°C for 40 minutes. Tissue was washed with PBS/0.05% Tween 20 twice for five minutes and blocked with 5% FBS and 0.2% gelatin for 30 minutes. Then, the tissue was stained with 10 µg/mL of purified anti-human CLA (clone HECA-452) overnight at 4°C. On the next day, tissue was incubated with Alexa Fluor® 647 goat anti-rat IgM (clone MRM-47) antibody (red) and Alexa Fluor® 594 anti-human CD45RO (Clone UCHL1) antibody (green) for an hour at room temperature. Nuclei were counterstained with DAPI (blue). The image was scanned with a 10X objective and stitched with MetaMorph® software.

    Human paraffin-embedded skin tissue slices were prepared with a standard protocol of deparaffinization and rehydration. Antigen retrieval was done with Citrate Buffered 1X (10mM, pH 6.0) at 95°C for 40 minutes. Tissue was washed with PBS/0.05% Tween 20 twice for five minutes and blocked with 5% FBS and 0.2% gelatin for 30 minutes. Then, the tissue was stained with 10 µg/mL of purified CLA (clone HECA-452) antibody at 4°C overnight. On the next day, tissue was incubated with Alexa Fluor® 647 anti-Rat IgM (clone MRM-47) antibody (red) and Alexa Fluor® 594 anti-human CD44 (clone IM7) antibody (green). The nuclei were conter-stained with DAPI (blue). The image was scanned with a 10X objective and stitched with MetaMorph® software.

Description

Cutaneous lymphocyte antigen (CLA) is a 140 kD homodimer protein recognized by a unique mAb, HECA-452. It is expressed on T cells in skin, subsets of peripheral blood memory T cells, NK cells, memory B cells and dendritic cells as well as on monocytes, granulocytes, and activated endothelial cells. CLA is a carbohydrate epitope of sialic acid and fucose-modified P-selectin glycoprotein ligand-1 (PSGL-1), a surface glycoprotein expressed on the majority of peripheral blood leukocytes. CLA is a ligand for E-selectin, P-selectin, and L-selectin. It plays a role in memory lymphocyte homing, tethering, and rolling.

Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 2.0 µg per million cells in 100 µl volume. For immunohistochemistry formalin-fixed paraffin-embedded tissue sections, a concentration range of 5.0 - 10.0 µg/ml is suggested. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

The HECA-452 antibody cross-reacts with mouse skin homing lymphocytes4. Treatment of activated HUVEC cells with HECA-452 antibody inhibits lymphocyte adhesion. Additional reported applications (for the relevant formats) include: blocking of lymphocyte binding to E-selectin3, and immunohistochemistry1,2 of acetone-fixed frozen sections and formalin-fixed paraffin-embedded sections.
