CD39L3/ENTPD3 antibody in Human Salivary Gland by Immunohistochemistry (IHC-P).

CD39L3/ENTPD3 in Human Salivary Gland.

CD39L3/ENTPD3 was detected in immersion fixed paraffin-embedded sections of human salivary gland using Sheep Anti-Human CD39L3/ENTPD3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4400) at 3 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to the plasma membranes of epithelial cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.
CD39L3/ENTPD3 antibody in Human Pancreas by Immunohistochemistry (IHC-P).

CD39L3/ENTPD3 in Human Pancreas.

CD39L3/ENTPD3 was detected in immersion fixed paraffin-embedded sections of human pancreas using Sheep Anti-Human CD39L3/ENTPD3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4400) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to pancreatic islets.

Background: CD39L3/ENTPD3

Ectonucleoside triphosphate diphosphohydrolase-3 (NTPDase-3), encoded by the ENTPD3 gene and also known as CD39L3, is an integral membrane protein with an extracellular active site (1). Recombinant human NTPDase-3 was expressed as a protein lacking its N- and C-terminal transmembrane domains, resulting in the secretion of the soluble ectodomain. NTPDase-3 hydrolyzes the beta - and gamma -phosphate residues of nucleotides, preferring ATP, ADP, UTP, and UDP as substrates (1). Through its hydrolysis of extracellular nucleotides, NTPDase-3 plays a role in the regulation of purinergic signaling (2). The enzyme is expressed at its highest levels in brain, pancreas, spleen and prostate tissues (3).
