Interpolated concentrations of spiked PTH in Human serum, plasma and cell culture media samples.

The concentrations of PTH were measured in duplicate, interpolated from the PTH standard curves and corrected for sample dilution. Undiluted samples are as follows : serum 50%, plasma (citrate) 50%, plasma (EDTA) 50%, plasma (heparin) 50% and 10F RPMI media 100%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean PTH concentration was determined to be 262.33 pg/mL in serum, 258.51 pg/mL in plasma (citrate) and 264.22 pg/mL in plasma (EDTA), 249.32 pg/mL in plasma (heparin), and 300.25 pg/mL in 10F RPMI media 100%.

Product details

Human PTH ELISA Kit ab230931 is a rapid single-wash 90-min Sandwich ELISA to measure Human PTH in citrate plasma, EDTA plasma, heparin plasma, serum. This SimpleStep sensitivity is 0.761 pg/mL.

How the assay works

Human PTH SimpleStep ELISA®employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details.

Assay Specificity

Our SimpleStep ELISA® kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

Supplementary information

Parathyroid hormone (PTH) also known as the parathyrin is a hormone protein with a molecular mass of about 9.4 kDa. It is synthesized and secreted by the chief cells of the parathyroid glands. PTH plays an important role in regulating calcium levels in the blood. Its molecular action involves binding to PTH receptors which are mainly located in bones and kidneys to increase calcium concentration by promoting its release from bones and reabsorption in the kidneys. This hormone is also present in the bloodstream as a parathyroid hormone peptide.
Biological function summary

PTH regulates calcium and phosphate metabolism in the body. It does not function as part of a larger complex but acts independently to control these important minerals. The hormone affects osteoclast activity in bones enhancing calcium and phosphate release. Additionally in the kidneys it reduces phosphate reabsorption while increasing calcium reabsorption. This balance maintained by PTH is essential for bone health and metabolic functions often associated with parathyroid hormone-related proteins in its activity.

Pathways

PTH is integral to the calcium signaling pathway and the renal phosphate reabsorption pathway. PTH works in concert with vitamin D to enhance intestinal calcium absorption. Calcitriol the active form of vitamin D depends on PTH for its synthesis in the kidneys linking the two in calcium homeostasis. Through these pathways PTH also interacts with the calcitonin hormone to moderate calcium levels creating a balance between mineral deposition and resorption in bones.

PTH is closely associated with hyperparathyroidism and hypoparathyroidism known as pan hypoparathyroidism when complete underactivity of the parathyroid glands occurs. In hyperparathyroidism an overproduction of PTH leads to high blood calcium levels and associated symptoms. Conversely hypoparathyroidism results in low calcium levels due to insufficient PTH secretion. Both conditions affect calcium metabolism and relate to proteins like calcium-sensing receptor and PTH-related peptide highlighting how critical PTH's function is in endocrine and metabolic health.

Target data

PTH elevates calcium level by dissolving the salts in bone and preventing their renal excretion. Stimulates [1-14C]-2-deoxy-D-glucose (2DG) transport and glycogen synthesis in osteoblastic cells.
