Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. Store undiluted at 4°C.

Recommended Assay Procedures

Functional Studies: Anti-HNK-1 monoclonal antibody recognizes a subset of NK lymphocytes and T lymphocytes. Unlike the populations of cells recognized by Anti-N-CAM monoclonal antibodies that share the unique ability to mediate direct, non-major histocompatibility complex-restricted cytotoxicity against certain tumor cells, the T lymphocytes recognized by anti-HNK-1 monoclonal antibody do not have NK activity. Anti-HNK-1 monoclonal antibodies can be used with other anti-N-CAM monoclonal antibodies to better understand the role of HNK-1 and N-CAM in leukocyte cytolytic activity against tumor cells. Anti-HNK-1 monoclonal antibody can be used in studies on the role of N-CAM and HNK-1 in the development and regulation of neuroendocrine tissues and muscle regeneration.

Immunohistology: Anti-HNK-1 monoclonal antibody can be used to stain paraffin-embedded tissues.

Immunoblotting: Anti-HNK-1 monoclonal antibody can be used in Western blot analysis.

Product Notices

  1. Please refer to for technical protocols.
  2. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

Antibody Details
Down Arrow Up Arrow

Anti-HNK-1 monoclonal antibody recognizes a 110 kD glycoprotein (CD57) that is expressed on a subset of natural killer (NK) lymphocytes and T lymphocytes. It also recognizes epitopes on neural or neuroectodermal tumors including neurofibromas, malignant melanomas, malignant peripheral neuroectodermal tumors, Ewing's sarcomas, and small-cell lung carcinomas. Anti-HNK-1 monoclonal antibody also recognizes a carbohydrate epitope on subpopulations of several cell-adhesion molecules including N-CAM and myelin-associated glycoprotein (MAG).

Format Details
Down Arrow Up Arrow
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
