techniques at the 400 bands of resolution were performed.
We have previously reported (3) a marked discrepancy between G-banding
and interphase FISH (iFISH) results at both initial diagnosis and follow-up.
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.
Variant Ph translocations were identified in all 6 patients using G-banding
analysis, and were confirmed via FISH analysis.
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.
They were taught state-of-the-art, hands-on cytogenetics techniques such as FISH (Fluorescent In Situ Hybridization--to identify different pieces of DNA on chromosomes), G-banding
(staining of chromosomes), and karyotyping (examination of cellular chromosomes aiding in disease diagnosis).
(HRB) analysis of 20 metaphases of the proband revealed a 46, XY, t(6;21) (q22;q13).
pythagoricus the identification of the chromosome pairs by means of G-banding
is also performed.
You may notice the remnants of a second centromere in the G-banding
pattern of the human chromosome corresponding to the centromere of one of the primate chromosomes.
