Product Overview

Tag	N/A
Host Species	Human
Accession	P11487
Synonym	HBGF-3, FGF3, Proto-oncogene Int-2, Heparin-binding growth factor 3
Background	FGF3 belongs to the FGF family, members of which act on cells of mesodermal and neuroectodermal origin. Originally designated int2, the FGF3 gene was initially identified as a protooncogene in mice. FGF3 plays an important role in the regulation of embryonic development, cell proliferation, and cell differentiation and is required for normal ear development. Heparan sulfate glycosaminoglycans function as co-receptors to increase the affinity between FGF3 and its receptors; FGFR1 and FGFR2. Human and mouse FGF3 are known to share 88% amino acid sequence identity. Recombinant Human FGF3 is a single polypeptide of 21 kDa.

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.
