Analysis of Ikzf1 Gene Rearrangement by Southern Blot Technology (CAT#: STEM-MHT-0038-LGZ)

Introduction

Official Full Name: IKAROS family zinc finger 1
Also known as: LyF-1; hlk-1; Ikaros; Zfpn1a1; Znfn1a1; mKIAA4227; 5832432G11Rik
The protein encoded by this gene belongs to a family of transcription factors characterized by a set of 4 DNA-binding zinc fingers at the N-terminus and 2 zinc fingers involved in protein dimerization at the C-terminus. It is jointly regulated by epigenetic factors and transcription factors. This protein is a transcriptional regulator of hematopoietic cell development and homeostasis. Furthermore, retinal progenitor cells are required to be temporally competent during embryogenesis, suggesting an important function in nervous system development. Alternative splicing results in multiple transcript variants encoding different isoforms.




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.
