Quantification of Ag-NOR proteins using Ag-NOR staining on western blots. [PDF]
Ribosomal genes are associated with a set of silver-stained nucleolar proteins, the Ag-NOR proteins, whose amount is directly related to the duration of the cell cycle. Quantification of Ag-NOR proteins by image analysis is presently used to evaluate the rate of proliferation of cancer cells and nucleolar activity.

Ag‐NOR" proteins are present when transcription is impaired
The use of nucleolar silver staining in plant cells in conditions of impaired transcription, either natural (quiescent cells) or induced (actinomycin D, ethidium bromide and cordycepin treatments), shows that nucleoli with very low transcription rates, compared with controls, contain similar amounts of argyrophilic proteins, as well as the same ...

An Experimental Approach to the Study of AG-NOR Proteins. [PDF]
Purified polyclonal antibodies have been obtained against 100 KD and 36 KD Ag-NOR proteins. These two antibodies have been used to study the immunolocalization of both proteins on different cell types subjected to various conditions of cell activity and to observe a nucleolar labelling with anti-36 kDa Ag-NOR protein antibody evenly ...

Variation in size and location of the Ag-NOR in the Atlantic halibut (Hippoglossus hippoglossus)
The distribution of differentially stained chromatin was studied in the Atlantic halibut (Hippoglossus hippoglossus) chromosomes (2n=48). Four pairs of homologous chromosomes were identified using a combination of traditional cytogenetic staining techniques (Giemsa/DAPI/CMA3/Ag-NO3).

Amount variability of total and individual Ag-NOR proteins in cells stimulated to proliferate. [PDF]
Ribosomal genes are associated with a subset of acidic proteins called Ag-NOR proteins. The amount of nucleolar Ag-NOR proteins varies, depending on nucleolar activity and/or cell proliferation. To understand the linkage between the amount of Ag-NOR proteins, ribosome biogenesis, and cell proliferation, we investigated the variability of Ag-NOR ...

Ag-NOR proteins and rDNA transcriptional activity in plant cells. [PDF]
In this work we used Allium cepa root meristem cells in actively growing conditions and under treatment with the protein synthesis inhibitors cycloheximide (CHM) and puromycin. Morphological and quantitative results indicate that these drugs induce dramatic alterations in nucleolar structure reflected by a decrease of nucleolar size, much more evident ...

Interindividual and intercellular polymorphisms of Ag-NOR pattern in mink embryo siblings [PDF]
La variabilite de la coloration a l'argent des regions des organisateurs nucleolaires (Ag-NOR) a ete etudiee sur des hepatocytes de 9 embryons de vison, germains de portee et incluant une paire de jumeaux monochorioniques, presumes monozygotes. A la fois le nombre des Ag-NOR et la taille moyenne des taches d'argent par cellule se sont trouves etre ...
