Product Overview

Tag	His
Host Species	Human
Synonym	WNT1 Inducible Signaling Pathway Protein 1, CCN Family Member 4, CCN4, Wnt-1 Inducible, Signaling Pathway Protein 1, WNT1 Induced Secreted Protein 1, Wnt-1-Induced Secreted Protein, CTC-458A3.8, WISP1tc, WISP1c, WISP1i, WISP-1, WISP1.
Background	WISP1 is a part of a family of cysteine-rich, glycosylated signaling proteins that mediate varied developmental processes. WISP1 is a Downstream regulator in the Wnt/Frizzled-signaling pathway and is linked with cell survival.WISP1weakens p53-mediated apoptosis in response to DNA damage through activation of AKT kinase and up-regulates the anti-apoptotic Bcl-X(L) protein.
Description	WISP1 Human Recombinant expressed in Mouse myeloma cell line is a single, glycosylated polypeptide chain containing 355a.a. (Thr23- Asn367), having a molecular weight of 39.3kDa and fused to a 10 a.a. His Tag.The WISP1 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.
