Product Overview

Tag	N/A
Host Species	Human
Synonym	Transforming Growth Factor-beta3, TGFB3, ARVD, FLJ16571, TGF-beta3.
Background	Transforming growth factor betas (TGF Betas) mediate many cell-cell interactions that occur during embryonic development. Three TGF Betas have been identified in mammals. TGF Beta 1, TGF Beta 2 and TGF Beta 3 are each synthesized as precursor proteins that are very similar in that each is cleaved to yield a 112 amino acid polypeptide that remains associated with the latent portion of the molecule.
Description	TGFB3 Human Recombinant expressed in E.Coli is a disulfide-linked homodimeric, non-glycosylated, polypeptide chain containing two 113a.a. chains and having a total molecular weight of 25.8kDa. The TGFB3 is purified by standard chromatographic techniques.
Source	E.coli
AA Sequence	MALDTNYCFRN LEENCCVRPL YIDFRQDLGW KWVHEPKGYY ANFCSGPCPY LRSADTTHST VLGLYNTLNP EASASPCCVP QDLEPLTILY YVGRTPKVEQ LSNMVVKSCK CS.
Purity	>95.0% as determined by SDS-PAGE.
Endotoxin	<1.0 EU per μg by the LAL method.
Bioactivity	The activity is determined by the ability to induce chondrogenic differentiation.
Formulation	The protein solution contains 20% Ethanol and 10mM Acetic acid (AcOH).
Stability	Recombinant protein is stable for 12 months at -70°C
Usage	For Research Use Only
Storage	TGF-beta 3 although stable at room temperature for 1 week, should be stored 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.
