Scientific Data

Immunohistochemistry GKAP antibody in Human Brain by Immunohistochemistry (IHC-P). View Larger

GKAP in Human Brain. GKAP was detected in immersion fixed paraffin-embedded sections of human brain (cortex) using Mouse Anti-Human GKAP Monoclonal Antibody (Catalog # MAB7296) at 15 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-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to the cytoplasm of neurons. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: GKAP/DLGAP1

GKAP, also known as DAP1, DLGAP, and SAPAP1, is an approximately 45 kDa cytoplasmic membrane associated protein. GKAP is a component of a neuronal postsynaptic complex that also includes PSD-95 and SHANK. This complex links neurotransmitter channels with the cytoskeleton and can promote NMDA R channel opening. Alternate splice forms of human GKAP have N-terminal and/or C-terminal truncations and are differentially expressed during brain development. Within aa 368-472 human, mouse, and rat GKAP share 100% aa sequence identity.
