Analysis of ETV6 Gene Rearrangement by Southern Blot Technology (CAT#: STEM-MHT-0035-LGZ)

Introduction

Official Full Name: ETS variant transcription factor 6
Also known as: TEL; THC5; TEL/ABL
This gene encodes an ETS family transcription factor. The product of this gene contains two functional domains: a N-terminal pointed (PNT) domain that is involved in protein-protein interactions with itself and other proteins, and a C-terminal DNA-binding domain. Gene knockout studies in mice suggest that it is required for hematopoiesis and maintenance of the developing vascular network. This gene is known to be involved in a large number of chromosomal rearrangements associated with leukemia and congenital fibrosarcoma.




Principle

Under certain conditions, two single strands of nucleic acid with certain homology can be specifically hybridized to form double strands according to the principle of base complementarity. Generally, DNA molecules to be detected are digested with restriction enzymes, separated by agar-gel electrophoresis, denatured and transferred to nitrocellulocellulose film or nylon film or other solid phase support according to their position in the gel, fixed and then reacted with DNA probes labeled with isotopes or other markers. This is followed by autoradiography or an enzyme reaction to detect the amount of specific DNA molecules. If the object to be tested contains a sequence that is complementary to the probe, the two are combined by the principle of base complementarity, and the free probe is washed and detected by self-development or other suitable techniques, thus revealing the fragment to be tested and its relative size.
