Anti-GALNT3 Antibody

GALNT3 (polypeptide N-acetylgalactosaminyltransferase 3) is a Golgi-resident glycosyltransferase that initiates mucin-type O-linked glycosylation by transferring N-acetylgalactosamine to serine and threonine residues on target proteins. This unconjugated rabbit polyclonal reagent from Antibodies.com was raised against the human GALNT3 target and is validated for Western blot and immunohistochemistry workflows on human samples.

Each vial ships with 100 µL of a 1 mg/mL stock solution in PBS, supplemented with 0.1% sodium azide as a preservative and 50% glycerol as a cryoprotectant. The glycerol-containing buffer allows short-term storage at 4 °C without freezing and long-term storage in a -20 °C freezer without loss of binding activity; repeated freeze-thaw cycles should be avoided by aliquoting the reagent on first use.

Because the host is rabbit and the reagent is polyclonal, the antibody pool recognises several distinct epitopes across the GALNT3 protein, giving broader tolerance to minor antigen masking in fixed IHC sections and stronger signal in Western blot detection of endogenous human GALNT3. The unconjugated format leaves the reporter chemistry open to the end user, supporting pairing with HRP-labelled, biotinylated, or fluorescently tagged secondary antibodies as required by the chosen detection system. Researchers investigating phosphate homeostasis, familial tumoral calcinosis, and mucin-type glycosylation pathways rely on this reagent to map GALNT3 expression across cell lines and tissue sections.
