Application Abreviews Notes
WB 1/3000. Detects a band of approximately 47 kDa (predicted molecular weight: 47 kDa).
IHC-P 1/1000. Perform heat mediated antigen retrieval via the microwave method before commencing with IHC staining protocol.

  • Function
    Receptor for GRF, coupled to G proteins which activate adenylyl cyclase. Stimulates somatotroph cell growth, growth hormone gene transcription and growth hormone secretion.
  • Tissue specificity
    Pituitary gland.
  • Involvement in disease
    Defects in GHRHR are a cause of growth hormone deficiency isolated type 1B (IGHD1B) [MIM:612781]; also known as dwarfism of Sindh. IGHD1B is an autosomal recessive deficiency of GH which causes short stature. IGHD1B patients have low but detectable levels of GH.
  • Sequence similarities
    Belongs to the G-protein coupled receptor 2 family.
  • Cellular localization
    Cell membrane.

  • ab28692 staining Human GHRHR in human ovarian carcinoma samples by immunohistochemistry using paraffin embedded tissue.

  • ICC/IF image of ab28692 stained SKNSH cells. The cells were 4% formaldehyde (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab28692, 1/200 dilution) overnight at +4°C. The secondary antibody (green) was ab96899 Dylight 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
