TGFB1 / TGF Beta 1 Protein LS-G30 is Recombinant Human TGFB1 / TGF Beta 1 in Human It is biologically active and is low in endotoxin Less than 0.1 ng/µg of protein (less than 1EU/µg)..
TGFB1 / TGF Beta 1
Predicted Molecular Weight
HEK 293 Cells
Greater than 98% by SDS-PAGE and HPLC
The ED50 as determined by TGF-beta1's ability to inhibit the mouse IL-4-dependent proliferation of mouse HT-2 cells is <=0.05 ng/ml, corresponding to a specific activity of >=2 x 10^7 units/mg.
Less than 0.1 ng/µg of protein (less than 1EU/µg).
Sterile filtered, lyophilized from 10 mM TFA
Centrifuge the vial prior to opening. Reconstitute in 10 mM Citric Acid pH 3.0 to a concentration of 0.1-1.0 mg/ml. Do not vortex. For extended storage it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
If lyophilized, can be stored for 1 month at room temperature, 6 months at 4°C, or through the expiration date at -20°C to -80°C. Once reconstituted per the supplied instructions, can be stored for 3 months at -20°C to -80°C, or for 1 week at 2°C to 8°C. Avoid freeze-thaw cycles.
