Our Abpromise guarantee covers the use of ab18200 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

|IHC-Fr||Use at an assay dependent concentration.|
FunctionSenses changes in the extracellular concentration of calcium ions. The activity of this receptor is mediated by a G-protein that activates a phosphatidylinositol-calcium second messenger system.
Tissue specificityExpressed in the temporal lobe, frontal lobe, parietal lobe, hippocampus, and cerebellum. Also found in kidney, lung, liver, heart, skeletal muscle, placenta.
Involvement in diseaseDefects in CASR are the cause of familial hypocalciuric hypercalcemia type 1 (FHH) [MIM:145980]. FHH is characterized by altered calcium homeostasis. Affected individuals exhibit mild or modest hypercalcemia, relative hypocalciuria, and inappropriately normal PTH levels.
Defects in CASR are the cause of neonatal severe primary hyperparathyroidism (NSHPT) [MIM:239200]. NSHPT is a rare autosomal recessive life-threatening disorder characterized by very high serum calcium concentrations, skeletal demineralization, and parathyroid hyperplasia. In some instances NSHPT has been demonstrated to be the homozygous form of FHH.
Defects in CASR are a cause of familial isolated hypoparathyroidism (FIH) [MIM:146200]; also called autosomal dominant hypoparathyroidism or autosomal dominant hypocalcemia. FIH is characterized by hypocalcemia and hyperphosphatemia due to inadequate secretion of parathyroid hormone. Symptoms are seizures, tetany and cramps. An autosomal recessive form of FIH also exists.
Defects in CASR are the cause of idiopathic generalized epilepsy type 8 (IGE8) [MIM:612899]; also known as EIG8. A disorder characterized by recurring generalized seizures in the absence of detectable brain lesions and/or metabolic abnormalities. Seizure types are variable, but include myoclonic seizures, absence seizures, febrile seizures, complex partial seizures, and generalized tonic-clonic seizures.
Note=Homozygous defects in CASR can be a cause of primary hyperparathyroidism in adulthood. Patients suffer from osteoporosis and renal calculi, have marked hypercalcemia and increased serum PTH concentrations.
Sequence similaritiesBelongs to the G-protein coupled receptor 3 family.
Ubiquitinated by RNF19A; which induces proteasomal degradation.
Cellular localizationCell membrane.

Performed under reducing conditions.
Observed band size: 130 kDa why is the actual band size different from the predicted?
Additional bands at: 200 kDa, 50 kDa, 80 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 3 minutes
In this experiment Hek293 was used as a negative control.
ab18200 staining CaSR in rat brain tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with paraformaldehyde. Samples were incubated with primary antibody (1/100 in PBST) for 24 hours at 20°C. A Biotin-conjugated Goat anti-rabbit IgG polyclonal (1/300) was used as the secondary antibody.
This antibody gave a weak staining using direct fluorescence, using amplification (secondary biotinylated) produced nice staining. Image taken in the hypothalamic paraventricular nucleus, the staining is not located on the cell membrane but rather on the cytoplasm or nucleus of the cells. B is a higher power magnification of A. The pictures were taken using objectives X10 and X40.
Lane 1 = HEK cell lysate used as negative control. Lane 2 = Post nuclear fraction of rat brain (P21). As secondary goat anti-rabbit HRP conjugated was used. Please see accompanying abreview for additional information
