一般描述

CD56, also known as a neural cell adhesion molecule (NCAM), is a calcium-independenthomophilic binding protein that belongs to a group of cell adhesion molecules includingcadherins, selectins, and integrins. CD56 is involved in cell-cell adhesion of neural cellsduring embryogenesis and is expressed in most neuroectodermally derived tissues. Innormal tissue, anti-CD56 labels neurons, glia, Schwann cells, NK (natural killer) cells, and asubset of T-cells. CD56 expression can be seen in most NK cell neoplasms,4 and is frequentlyused to identify neoplasms with neuroendocrine differentiation.

We report an unusual case of aggressive natural killer (NK)-like cytotoxic T-cell lymphoma in a previously healthy immunocompetent West African male. He presented with a fever of unknown origin, subsequently developed erythematous skin nodules, generalized lymphadenopathy, and hepatosplenomegaly, and then

The presence of the neural cell adhesion molecule, NCAM, is indicative for a poor prognosis in lung-cancer patients. Using MAb 735, we have investigated the expression of polysialic acid, PSA, on NCAM in a spectrum of neuro-endocrine lung tumors, ranging

CD56 is immunohistochemically detectable in virtually all small cell carcinomas on frozen sections. The authors retrospectively tested the usefulness of the monoclonal antibody 123C3 against CD56 to differentiate pulmonary and extrapulmonary small cell carcinomas from nonneuroendocrine non-small cell carcinomas by

Unlike monoclonal gammopathy of undetermined significance (MGUS) or non-Hodgkin's lymphomas (NHLs) with plasmacytoid differentiation, multiple myeloma (MM) is commonly associated with lytic bone lesions. Although the mechanisms of increased osteoclast activity are partially understood, comparatively little is known about the

Questions

1–3 of 3 Questions  
  1. Which isoforms of the CD56 antigen does the CD56 MRQ-42 clone recognize? I am curious about the 120kD, 140kD, and 180 kD isoforms, in particular.

    1 answer
    1. Unfortunately, the specific isoforms that this antibody reacts to have not been investigated. The immunogen is from the C-terminus. Please see the links below to review additional information that may be helpful:

  2. What is the stability of cut slides for staining with the CD56 MRQ-42 clone, particularly for slides that have been sectioned 6 months to 1 year ago and stored at -20°C with desiccant?

    1 answer
    1. It is generally recommended to begin with fresh cut tissue for use in IHC. When storing pre-cut tissue slides, it is typically done under refrigerated conditions (2 to 8°C), which can last for 2 to 3 years. However, the potential effects of storing at temperatures of -20°C with desiccant are not well-known in terms of tissue preservation. The best practice is to always use fresh cut tissue sections when possible.

  3. Is there information on what terminus was for CD56 MRQ-42?

    1 answer
    1. Based on the information available, it seems that it is C-terminus.
