更新時間:2022-01-28

簡要描述:

Oxytocin ELISA kit
The most sensitive, specific and flexible alternative to more costly and time-consuming methods for oxytocin detection.

型號:廠商性質(zhì):代理商瀏覽量:843
  • Highly specific ELISA which does not detect vasopressin, providing confidence in assay results

  • Ultra-sensitive measurement, detecting as little as 15pg/ml oxytocin

  • Cost effective solution, faster and less costly than LC/MS

  • Easy-to-use liquid color-coded reagents and pre-coated plates minimizes errors

  • Widely published in peer reviewed literature

The Oxytocin EIA kit is a colorimetric competitive enzyme immunoassay kit with results overnight + 1 hour. Absorbance is read at 405 nm. Very low reactivity with vasopressin provides confidence in assay results. Sensitive quantification of 15pg/mL oxytocin. Ready-to-use liquid color-coded reagents reduce errors in the lab.

Scientific Background:Oxytocin is a neurohypophysial peptide which is produced in the paraventricular nuclei of the hypothalamus and stored in the posterior pituitary. The molecule consists of nine amino acids linked with a [1-6] disulfide bond and a semi-flexible carboxyamidated tail. A hormone once thought to be limited to female smooth muscle reproductive physiology, more current findings have determined that oxytocin also functions as a neurotransmitter, may be involved in neuropsychiatric disorders, social/sexual behavior, and is important in male reproductive physiology. Oxytocin and the related neurohypophysial peptide, Arg-Vasopressin, maintain renal water and sodium balance.
