Anti-PEX19 Antibody

The PEX19 protein (Peroxisomal Biogenesis Factor 19) functions as a cytosolic chaperone and shuttling receptor that delivers newly synthesized peroxisomal membrane proteins from the cytosol to the peroxisomal membrane, a step required for proper organelle assembly. This unconjugated rabbit polyclonal antibody from Antibodies.com was raised against human PEX19 and is validated for Western blot, immunohistochemistry, and immunofluorescence workflows on human samples.

Each vial contains 100 µl of antibody supplied as a liquid reagent that can be aliquoted to limit freeze-thaw exposure. Store at -20 °C in working aliquots, protect from light, and avoid repeated freeze-thaw cycles to preserve binding activity. The polyclonal format recognizes multiple epitopes on the PEX19 target, supporting detection in whole-cell lysates, formalin-fixed tissue sections, and adherent cell monolayers.

Researchers investigating peroxisome biogenesis, Zellweger spectrum disorders, or membrane protein trafficking pathways rely on PEX19 as a marker of peroxisomal integrity. The antibody's reactivity with human PEX19 makes it well suited for studies in HeLa, HEK293, and other human-derived cell lines, as well as patient biopsy material relevant to peroxisomal disease research, mitochondrial metabolism, and organelle inheritance.
