Description

HDEL Antibody [2E7]

HDEL Antibody [2E7] is a mouse monoclonal antibody directed against HDEL, offered by Assay Genie for research applications. Reported applications include WB and ICC/IF. Reported reactivity: Fruit Fly (Drosophila melanogaster), Yeast, Yeast (Saccharomyces cerevisiae), Plant, Barnyard Grass (Echinochloa), Beet (Beta vulgaris), Cotton (Gossypium), Mung Bean (Vigna radiata), Grass (Sorghum) and Wheat (Triticum spp.). Supplied as IgG2b, purified by Protein G.

The HDEL sequence (His-Asp-Glu-Leu) is a C-terminal ER retention signal found in many soluble endoplasmic reticulum (ER) resident proteins. It plays a critical role in maintaining ER homeostasis by ensuring that chaperones and folding enzymes are retained or retrieved from the Golgi apparatus back to the ER. In neurodegenerative diseases, where ER stress and protein misfolding are prominent pathological features, the HDEL motif is essential for the proper localization and function of ER-resident proteins such as GRP78, GRP94, and protein disulfide isomerases. Disruption of HDEL-mediated retention can impair the unfolded protein response (UPR), exacerbate proteotoxic stress, and contribute to neuronal dysfunction. Moreover, the efficiency of the HDEL retrieval system may decline with age or under chronic stress, potentially leading to the mislocalization of protective chaperones and increased vulnerability to neurodegeneration. Understanding the dynamics of HDEL-mediated trafficking offers insights into ER stress regulation and may inform therapeutic strategies aimed at enhancing proteostasis in neurodegenerative disorders. This antibody is also available conjugated to ATTO 390, ATTO 488, ATTO 594, APC, Biotin, FITC, HRP, PerCP and RPE. Supplied in 100 µg. For research use only; not for diagnostic or therapeutic procedures.
