Product Overview

Tag	N/A
Host Species	Human
Synonym	Wingless-Type MMTV Integration Site Family, Member 7A, Proto-Oncogene Wnt7a Protein, Protein Wnt-7a.
Background	Wingless-Type MMTV Integration Site Family, Member 7A also known as WNT7A belongs to the WNT gene family, this family consists of structurally related genes which encode secreted signaling proteins. These proteins have been implicated in oncogenesis and in several developmental processes, including regulation of cell fate and patterning during embryogenesis. WNT7A is involved in the development of the anterior-posterior axis in the female reproductive tract, and also plays an essential role in uterine smooth muscle pattering and maintenance of adult uterine function. In addition, Mutations in WNT7A have been associated with Fuhrmann and Al-Awadi Raas-Rothschild Schinzel phocomelia syndromes.
Description	WNT7A Human Recombinant expressed in E.Coli is a single, non-glycosylated polypeptide chain containing 341a.a. (32-349 a.a) and having a molecular weight of 38kDa.WNT7A is fused to a 23a.a. His-tag at N-terminus and 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.
