General description

Cell replacement techniques such as stem-cell or fetal-cell therapies show great promise for many diseases. Cross-species grafting between human and animal cells or tissues requires the identification and localization of the donor material in the host environment. Antibodies to human-specific nuclei are useful cytological and histological markers for identifying human cells in xenograft models.


Stains nuclei of all human cell types giving a diffuse nuclear staining pattern. Chromosomes are negatively stained in metaphase cells. Also stains nuclei from primate (Sanchez-Pernaute, 2005). The antibody does not react with nuclei from mouse or rat.

The human nuclei monoclonal reacts specifically with human cells. It shows no reactivity against mouse, rat, chicken in immunohistorchemistry. Other mammalian or animal species have not been tested for reactivity.


Immunohistochemistry/cytochemistry: 4% PFA fixed cryosections, or 5-10 minuted fixed cell cultures. Acetone fixation is also effective. Permeabilization with 0.1-0.4% triton X-100 is suggested in the blocking buffer. Dilution will vary slightly with lot; use at 1:10-1:500.

Formalin fixed, paraffin embedded tissues: 1:20 for 1hr at RT. Citrate buffer epitope retrieval method recommended.

Identifies an 82 and 70 kD protein by immunoprecipitation.

Optimal working dilutions and protocols must be determined by the end user.
