HECA-452_A594_CLA_Antibody_1_053118
Human paraffin-embedded tonsil tissue slices were prepared with a standard protocol of deparaffinization and rehydration. Antigen retrieval was done with Citrate Buffered 1X (10 mM, 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 10µg/mL of Alexa Fluor® 594 anti-CLA (Clone HECA-452) antibody (red) and Alexa Fluor® 647 anti-CD45RA (Clone HI100) antibody (green) over night at 4°C. Nuclei were counterstained 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.

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.
