    Human paraffin-embedded cerebellum tissue slices were prepared with a standard protocol of deparaffination and rehydration. Antigen retrieval was done with Citrate-Buffered Saline 1X (pH6.0 at 95°C for 40 minutes. Tissue was washed with PBS/ 0.05% Tween20 twice for 5 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-CD57 (clone HNK-1) overnight. On the next day, tissue was incubated with Alexa Flour® 647 anti-mouse IgM (Clone RMM-1) antibody (red), Alexa Flour® 594 anti-TUBB3 (Clone AA10) antibody (blue) and Brilliant Violet 421™ anti-GFAP Antibody (green) overnight at 4°C. The image was scanned with a 10X objective and stitched with MetaMorph® software.

Description

CD57, also known as HNK-1, NK-1, and Leu-7 is a 100-115 kD oligosaccharide antigenic determinant expressed on a variety of proteins, lipids, and chondroitin sulfate proteoglycans. CD57 is expressed on a subset of peripheral blood lymphocytes, including NK cells and CD8+ T cells, and is also expressed on neural cells and striated muscle. CD57 is not expressed on red blood cells, granulocytes, monocytes, or platelets. While the function of CD57 is unknown, binding to L-selectin, P-selectin, and a fragment of laminin suggests that CD57 may be involved in cell-matrix interactions. CD57 is increased in some disease states associated with CD4/CD8 imbalances (AIDS, autoimmune disease, viral infections, and allograft transplants).

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 ≤0.5 µg per million cells in 100 µl volume. For immunohistochemistry, 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.
