Product Specific Information

1 µg/mL of MA5-45243 was sufficient for detection of HDEL-containing proteins in 10 µg of S. cerevisiae lysate by colorimetric immunoblot analysis using Goat anti-mouse IgG:HRP as the secondary antibody. Detects approximately 78 kDa.

Target Information

The HSP70 family comprises four highly conserved proteins — HSP70, HSC70, GRP75, and GRP78 — functioning as molecular chaperones. They assist in multi-protein complex assembly, translocation of polypeptides across membranes, and proper folding of nascent chains.
GRP78 resides in the endoplasmic reticulum (ER), handling secretory proteins and facilitating folding and translocation. Protein sorting depends on a C-terminal tetrapeptide signal, typically KDEL in animal cells and HDEL in S. cerevisiae.
Clone 2E7 recognizes the C-terminal HDEL peptide, a common ER retention signal in yeast, plants, nematodes, and other species. It specifically stains HDEL proteins in barnyard grass, beet, cotton, mung bean, sorghum, and wheat.
