Product Information

Product Usage Information

Application Dilution
Western Blotting 1:1000

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

GILT (E3P1D) Rabbit mAb recognizes endogenous levels of total GILT protein. This antibody cross-reacts with a 170 kDa protein of unknown identity in some cell extracts.

Species Reactivity:

Human

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly111 of human GILT protein.

Background

Gamma-interferon-inducible lysosomal thiol reductase (GILT) is synthesized as a precursor glycoprotein, which is proteolytically processed intracellularly into a mature lysosomal thiol oxidoreductase. Research studies have shown that GILT participates in protein thiol reduction within the endosomal pathway and may contribute to shaping the repertoire of epitopes that undergo MHC class II-dependent presentation (1-3). Additional studies have demonstrated that GILT serves as a restriction factor for multiple RNA-based viruses by inhibiting viral entry (4). Given the role of antigen presentation in facilitating an anti-tumor immune response, research studies have suggested that elevated GILT expression in multiple types of human cancers serves as a biomarker for improved survival and response to immune checkpoint blockade (5-8).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
