    8-10 FISH

    Fluorescence in situ hybridization (FISH)
    The target DNA is hybridized with a fluorescent probe. Using a light with a specific wavelength, the fluorescent site in the chromosome is detected as a signal by fluorescence microscope.
    The direct method uses a fluorescent probe to directly bind to the target DNA. The indirect method uses a labeled probe to bind to the target DNA which is subsequently bound to a fluorescence substance for color development.

COMMENT


Avoid freezing.
Uniparental disomy cannot be tested.
Orders accepted on specified days. Orders can be accepted from Monday through Thursday.
Please order a test for the name of disease concerned.
This test does not detect the gene that is directly related to the disease, but it judges deficiency of the gene in the responsible field.
Contact us if blood drawn from newborns does notsatisfy the required volume.
About the submission of samples for chromosomal tests
Please submit a sample on the day it is collected.
Subject to ethical guidelines for human genes.(See below)
After drawing blood into a container shown in the left image, mix well, and refrigerate the specimen.
