Product Overview

Tag Flag
Host Species Human
Synonym Vitamin D3 receptor, VDR, 1,25-dihydroxyvitamin D3 receptor, Nuclear receptor subfamily 1 group I member 1, VDR, NR1I1.
Background Vitamin D receptors (VDRs) belong to the NR1I family, which also includes pregnane X (PXR) and constitutive androstane (CAR) receptors which form heterodimers with members of the retinoid X receptor family. VDR is expressed in the intestine, thyroid and kidney and has an imperative role in calcium homeostasis. VDRs inhibit expression of 1alpha-hydroxylase (the proximal activator of 1,25(OH)2D3 and induce expression of the 1,25(OH)2D3 inactivating enzyme CYP24. Additionally, VDR has recently been recognized as an additional bile acid receptor alongside FXR and may function to protect gut against the toxic and carcinogenic effects of these endobiotics. Hereditary mutations in the VDR gene leads to rickets, which is typified by muscle weakness, growth retardation, bone deformity and secondary hyperparathyroidism. The human gene encoding the VDR is localized to chromosome 12q12-q14.
Description Vitamin D Receptor Human Recombinant expressed in E.Coli is a full length protein consisting of 427a.a. having a molecular weight of 48.3kDa and fused with 5.5kDa amino-terminal His-Flag tag.VDR is purified by unique purification methods.

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
