Description
Background:

Growth differentiation factor-3 (GDF3) also known as Vg-related gene 2 (Vgr-2), is a protein belonging to the transforming growth factor beta (TGF-β) superfamily. It has high similarity to other TGF-β superfamily members called Vg1, BMP2, BMP6 and GDF1, but lacks one of the conserved cysteine residues common to all other TGF-β superfamily members.1 Expression of GDF3 occurs in ossifying bone during embryonic development and in the brain, thymus, spleen, bone marrow and adipose tissue of adults.2,3
GDF3 is a bi-functional protein that inhibits some TGF-β superfamily members (e.g. BMPs) while activating others, thus regulating the balance between different modes of TGF-beta signaling.4 GDF3 regulates both of the two major characteristics of embryonic stem cells: the ability to maintain the undifferentiated state and the ability to differentiate into the full spectrum of cell types.5

State of Matter
 
Purity
>98% by SDS Page and HPLC
Storage and Stability
The lyophilized protein should be stored desiccated at -20°C. The reconstituted protein can be stored for at least one week at 4°C. For long-term storage of the reconstituted protein, aliquot into working volumes and store at -20°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles.
Endotoxin
<1.0 EU/µg
Biological Activity
The biological activity of Human Growth/Differentiation Factor-3 is determined by its ability to inhibit induced alkaline phosphatase production by ATC\DC-5 chondrogenic cells. The expected ED50 for this effect is 100-150 ng/ml.
Each investigator should determine their own optimal working dilution for specific applications.
