Detection of unidentified chromosome abnormalities in human neuroblastoma by spectral karyotyping (SKY) (CAT#: STEM-ST-0384-WXH)
Introduction
Neuroblastoma (NB) is a type of cancer that forms in certain types of nerve tissue. It most frequently starts from one of the adrenal glands but can also develop in the head, neck, chest, abdomen, or spine. Symptoms may include bone pain, a lump in the abdomen, neck, or chest, or a painless bluish lump under the skin.
Principle
It is based on the hybridization of collections of chromosome-specific FISH probes labeled with different fluorochromes or fluorochrome combinations, allowing the discrimination of each of the 24 different human chromosomes.
Applications
Detection of subtle chromosomal aberrations, including marker chromosomes, small translocations, complex rearrangements and minute structural abnormalities.
