Fluorescence banding patterns of the rat chromosomes

Chromosoma, 1972
The quinacrine-fluorescence karyotype was analysed in 7 rats of Wistar-King A (WKA/Mk) and Wistar (W/Mk) strains. All 20 pairs of autosomes and the X and Y chromosomes have been identified. No polymorphic band has been found within or between the strains.

On the Chemical Basis of Chromosome Banding Patterns

Stain Technology, 1975
A comparative study of the staining characteristics of four reagents for human chromosomes has been carried out. The four reagents are: (I) quinacrine mustard, as an alkylating agent, (II) the dihydroxy derivative of quinacrine mustard, (III) quinacrine, and (IV) 9-amino-6-chloro-2-methoxyacridine.

G-Band Patterns of Swine Chromosomes

Journal of Heredity, 1975
A simple inexpensive and reproducible G-banding technique for swine chromosomes is described that permits precise identification of individual chromosome pairs. The G-bands were obtained by either SSC (saline-citrate-solution), or trypsin pretreatment methods.

Inversion of Band Patterns in Spherical Tumblers

Physical Review Letters, 2009
Bidisperse granular mixtures in spherical tumblers segregate into three bands: one at each pole and one at the equator. For low fill levels, large particles are at the equator; for high fill levels, the opposite occurs. Segregation is robust, though the transition depends on fill level, particle size, and rotational speed.

Giemsa banding patterns of human chromosomes*

Clinical Genetics, 1972
A method of obtaining differentially stained chromosomes is described. The method based on the treatment of the chromosomes with NaOH and subsequent incubation in phosphate buffer and Giemsa staining gave distinct banding patterns in both blood and bone marrow chromosomes.

Masking patterns in band-rejected noise

The Journal of the Acoustical Society of America, 1974
Masking audiograms were determined in the presence of wide-band noise from which a band of frequencies 3/4 octave wide had been rejected. The center of the band-reject gap was adjusted to correspond to 500, 1000, 2000, or 4000 Hz, and two overall noise levels (45 or 65 dB SPL) were used.

Chromosome Banding Patterns in Preimplantation Mouse Embryos

Science, 1972
The chromosomes of first cleavage mouse embryos show the same banding patterns after quinacrine mustard staining as do chromosomes of differentiated mouse cells. Whatever feature of chromosome structure the banding pattern reveals thus appears not to be altered during development and differentiation.

The Banding Pattern of Collagen

1985
When viewed in the electron microscope, one of the most striking structural features displayed by collagen is the regular banding pattern of its fibrils. This pattern, with a period (D) of ~65 nm in vertebrate collagens, is readily apparent after exposure to a staining solution of a heavy metal salt.

Chromosome Banding Pattern in Acute Myeloid Leukaemia

Scandinavian Journal of Haematology, 1974
Using the Giemsa technique the chromosome banding pattern was determined in bone marrow cells of 10 untreated patients with a recent diagnosis of acute myeloid leukaemia. 5 patients had a completely normal banding pattern whereas 5 patients had cells with karyotypic abnormalities.

A system of nomenclature for band patterns of mouse chromosomes

Chromosoma, 1973
Mouse chromosomes banded by quinacrine mustard staining, by the ASG technique, or by Giemsa staining following trypsinization or chymotrypsinization are described in detail. Three hundred and twelve regions within the mouse karyotype can be distinguished and a simple system of nomenclature is proposed for naming these regions.
