G banding

(redirected from G-banding)

G banding

A method of identifying the different members of a haploid set of metaphase chromosomes by means of staining that reveals their individual pattern of stripes.

G banding

a method of treating chromosomes with Giemsa stain to show areas of the chromosomes with light and heavy staining. Such patterns are different for each chromosome type and thus are most useful when arranging chromosomes in KARYOTYPE analysis.

Although routine cytogenetic analysis by G-banding can detect common trisomies and some structural abnormalities, it is unable to define the precise breakpoint of terminal deletions.
Due to the patient's linear skin pigmentation, an initial 30-cell G-banding screen from lymphocyte culture was carried out alongside the microarray analysis to rule out the possibility of mosaicism.
In this study, we assessed chromosome stability in eMSC that survived SHS using G-banding and molecular karyotyping.
(2) Presently, the evaluation of chromosomal abnormalities for cytogenetic response is based on standard G-banding, whereas the utility of fluorescence in situ hybridization (FISH) is still debated.
G-banding with trypsin treatment and Giemsa stain (GTG-banded) chromosome analysis showed a mosaic karyotype with two cell lines: five cells with a 45,X karyotype and 15 cells with a 46,XY karyotype.
We karyotyped amniocytes or maternal WBCs via G-banding analysis of metaphase chromosome spreads at 450-band resolution.
Unlike traditional karyotyping methods such as G-banding or FISH analysis that are time consuming, labor intensive, and cannot be easily scaled for many samples at once, nCountcr assays are simple and easy to use for any laboratory scientist.
