一般說明
CD44 is a glycosylated cartilage-linked protein. The protein exists in a variety of forms with different molecular structures, ranging from 85 kDa to 250 kDa. It is a multistructural and multifunctional cell surface molecule and involved in various biological processes such as cell proliferation, cell differentiation, cell migration, angiogenesis, presentation of cytokines, chemokines, and growth factors to the corresponding receptors, and docking of proteases at the cell membrane, as well as in signaling for cell survival. Although all the activities are related to normal cell, but it has also some pathologic activities of cancer cells.
特異性
Recognizes the CD44 (80-95 kDa) human cell surface glycoprotein on B and T lymphocytes, monocytes, granulocytes and red blood cells. The epitope recognized by this antibody is sensitive to bromelain and other proteolytic enzymes. It is detectable in routine formalin-fixed, paraffin-embedded tissue.

生化／生理作用
The CD44 antigen is expressed on a variety of cell types including peripheral blood leukocytes (B and T lymphocytes, monocytes, granuloctes) and red cells. It is also weakly expressed on platelets. The antibody is also reactive with bone marrow nucleated cells, medullary thymocytes, liver Kupffer cells, fibroblasts, corneal cells, epidermal keratinocytes, synovial cells, a subset of pancreatic acinar cells and brain cells. The epitope recognized by this clone is sensitive to formalin fixation and paraffin embedding.
標靶描述

CD44 antigen is the cellular receptor for hyaluronic acid. The antibody is also reactive with bone marrow nucleated cells, medullary thymocytes, liver Kupffer cells, fibroblasts, corneal cells, epidermal keratinocytes, synovial cells, a subset of pancreatic acinar cells and brain cells.
外觀
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide.
儲存和穩定性
Store at 2-8°C for up to one month. For extended storage, the solution may be frozen in working aliquots. Repeated freezing and thawing, or storage in "frost-free" freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.
