SPECIES REACTIVITY:H, M, R
TESTED APPLICATIONS:E, WB
APPLICATIONS:LGI4 antibody can be used for the detection of LGI4 by Western blot at 1-2 μg/mL.
USER NOTE:Optimal dilutions for each application to be determined by the researcher.
POSITIVE CONTROL:1) Cat. No. 1463-Rat Brain Tissue Lysate
SPECIFICITY:Two isoforms of LGI4 are known to exist; this LGI4 antibody will recognize only the larger form. This LGI4 antibody is predicted to be specific to LGI4 and not recognize other LGI proteins.
IMMUNOGEN:LGI4 antibody was raised against a 17 amino acid synthetic peptide from near the carboxy terminus of human LGI4.
HOST SPECIES:Rabbit

Properties

PURIFICATION:LGI4 Antibody is affinity chromatography purified via peptide column.
PHYSICAL STATE:Liquid
BUFFER:LGI4 Antibody is supplied in PBS containing 0.02% sodium azide.

Background

BACKGROUND
LGI4 Antibody: The leucine-rich, glioma inactivated gene 4 (LGI4) is a member of the LGI family in which LGI1 is the exemplar. The LGI family consists of four of highly related proteins containing leucine-rich repeats (LRRs) which are highly similar to other transmembrane signaling molecules and receptors. LGI1 has been identified as a candidate tumor suppressor gene for glioma and plays a role in autodominant lateral temporal epilepsy (ADTLE), an epileptic syndrome characterized by focal seizures with predominant auditory symptoms. Despite its high homology with LGI1 and similar pattern of expression, mutations in LGI4 have not been found to be associated with ADTLE. However, the LGI4 gene is located in a region linked to benign familial infantile convulsions. Further study revealed that a GC-to-AT polymorphism was correlated with childhood absence epilepsy. Other studies showed that decreasing LGI4 expression in cultured cells inhibits myelination, indicating that LGI4 may play a role in neural development.
