≥98% by SDS-PAGE

< 1EU per µg

The ED50 measured by TGFβ1’s ability to inhibit mIL-4-dependent proliferation of HT-2 mouse helper T cells is <0.5ng/ml.

Lyophilized from a 0.2 µm filtered, aqueous solution

lyophilized protein

Reconstitute in sterile 0.2 M acetic acid with 0.1% BSA. Further dilutions may be made in PBS with 0.1% BSA. To maximize product collection from vial surface, vortex briefly and then spin down to recollect the liquid.

>6 months at –80°C (as a solid). Store reconstituted protein in aliquots at –80°C for up to 3 months. Avoid freeze/thaw cycles.

Useful for cell culture and for the study of signaling and apoptotic pathways.
