PADI2 was detected in immersion fixed paraffin-embedded sections of human Alzheimer's brain (cortex) using Sheep Anti-Human PADI2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7257) 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 counter-stained with hematoxylin (blue). Specific staining was localized to glial cells.

Background: PADI2

PADI2 (Protein-arginine deiminase type 2; also PAD2, PDI2 and PAD-H19) is a 72-76 kDa member of the PAD family of proteins. It is widely expressed, being found in macrophages, astrocytes, select neurons, skeletal muscle and bronchial epithelial cells, and keratinocytes. PADI2 catalyzes the Ca++-dependent conversion of guanidino groups (NH2-C[=NH]-NH−) to ureido groups (NH2-C[=O]-NH-) on peptidylArg, a posttranslational process known as citrullination. Human PADI2 is 665 amino acids (aa) in length. It contains an N-terminal PAD domain (aa 1-114), a middle PAD-M domain (aa 116-274), and a catalytic region (aa 279-665). Over aa 1-115, human PADI2 shares 90% aa sequence identity with mouse PADI2.
