Product Overview

Tag	His
Host Species	Human
Synonym	Fibroblast growth factor 18, FGF-18, zFGF5, FGF18.
Background	Fibroblast growth factor 18 (FGF18) is a member of the large FGFfamily which has at least 23 members. FGF18 is a binding growth factor with a core 120 amino acid FGFdomain which allows for a common tertiary structure. FGFs are expressed in the course of the embryonic development and in restricted adult tissues. FGF-18 is an indispensable regulator of long bone and calvarial development. FGF-18 signals via FGFR 1c, 2c, 3c, and 4.
Description	FGF18 Human Recombinant expressed in E.Coli is a single, non-glycosylated, polypeptide chain (Glu28-Ala207) containing 190a.a. including a 10 a.a. His tag at N-terminus. The total calculated molecular weight is 22.3kDa.
Source	E.coli

Purity	Purity as determined by densitometric image analysis is >95%.
Endotoxin	<1.0 EU per μg by the LAL method.
Formulation	FGF18 was filtered (0.4µm) and lyophilized in phosphate buffered saline and 5% w/v trehalose.
Stability	Recombinant protein is stable for 12 months at -70°C
Usage	For Research Use Only
Storage	Store lyophilized protein at -20°C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles. Reconstituted protein can be stored at 4°C for a limited period of time; it does not show any change after two weeks at 4°C.

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.
