Principle of the Assay: This kit is based on sandwich enzyme-linked immune-sorbent assay technology. Anti-Renin-1 monoclonal antibody is pre-coated onto 96-well plates. Biotin conjugated anti-Renin-1 polyclonal antibody is used as detection antibodies. The standards, test samples and biotin conjugated detection antibody are added to the wells subsequently, and washed with wash buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with wash buffer. TMB substrates are used to visualize HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow is proportional to the Renin-1 amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of Renin-1 can be calculated.
Background: The secretion of renin from granules stored in renal juxtaglomerular cells plays a key role in blood pressure homeostasis. The synthesis and release of renin and the extent of granulation is regulated by several mechanisms including signaling from the macula densa, neuronal input, and blood pressure. Clark AF et al study indicate that expression of the Ren-1(d) gene is a prerequisite for the formation of storage granules, even though the related protein renin-2 is present in these mice, suggesting that renin-1(d) and renin-2 are secreted by distinct pathways in vivo. The synthesis of renin and other biologically active polypeptides in the granular convoluted tubule cells of the mouse submandibular gland (SMG) is regulated by androgen and thyroid hormones. The androgen and thyroid hormones influence levels of renin-1 in mouse SMG primarily by regulating the amount of renin-1 mRNA available for translation.
NCBI and Uniprot Product Information
Uniprot Description
Renin is a highly specific endopeptidase, whose only known function is to generate angiotensin I from angiotensinogen in the plasma, initiating a cascade of reactions that produce an elevation of blood pressure and increased sodium retention by the kidney.

Product Notes
The Ren1 ren1 (Catalog #AAA490247) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. 90 min. incubation (37 degree C) + 1 hour (37 degree C) + 30 min. (37 degree C) + 30 min. (37 degree C) = 3 hours, 30 min. total incubation time. Researchers should empirically determine the suitability of the Ren1 ren1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Renin-1, ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
