USP18 Antibody Summary

Description
This affinity-purified antibody is directed against human USP18 protein. The product was affinity purified from monospecific antiserum by immunoaffinity purification

Store vial at -20C prior to opening. Aliquot contents and freeze at -20C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4C as an undiluted liquid. Dilute only prior to immediate use.
Immunogen
This affinity purified USP18 Antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to an internal region near aa 25-50 of human USP18 protein. (Uniprot: Q9UMW8)
Specificity
This affinity-purified antibody is directed against human USP18 protein. A BLAST analysis was used to suggest reactivity with this protein from human, chimpanzee and orangutan based on 100% homology for the immunogen sequence. The core 7 amino acid sequence QPRERPR of the 10 amino acid immunogen sequence may be reactive with USP18 from mouse and dog. This core sequence also shows partial homology with proteins other than USP18. Cross reactivity with USP18 homologues from other sources has not been determined.

Applications/Dilutions

Dilutions
  • ELISA 1:10000-1:50000
  • Immunocytochemistry/ Immunofluorescence 1:10-1:500
  • Western Blot 1:500-1:2000
Application Notes
This affinity purified antibody has been tested for use in ELISA and by western blot. Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 43 kDa in size corresponding to UBP43 by western blotting in the appropriate cell lysate or extract.
Control
USP18 Overexpression Lysate

Reactivity Notes

A BLAST analysis was used to suggest reactivity with this protein from human, chimpanzee and orangutan based on 100% homology for the immunogen sequence. The core 7 amino acid sequence QPRERPR of the 10 amino acid immunogen sequence may be reactive with USP18 from mouse and dog. This core sequence also shows partial homology with proteins other than USP18. Cross reactivity with USP18 homologues from other sources has not been determined.

Background

UBP43, also known as ISG43 or USP18 is a member of the deubiquitinating protease family of enzymes, which removes ubiquitin adducts from a broad range of protein substrates. Deletion of the UBP43 gene in mouse leads to a massive increase of ISG15 conjugates in tissues indicating that UBP43 is a major ISG15-specific protease. UBP43 is the first bona fide ISG15-specific protease reported. Both ISG15 and UBP43 genes are known to be strongly induced by interferon, genotoxic stress, and viral infection. Thus UBP43 may be necessary to maintain a critical cellular balance of ISG15-conjugated proteins in both healthy and stressed organisms.
