General description
Protein delivery system, Human TGF-β1, PODS contains the polyhedrin protein co-crystalized with Human TGF-β1. Transforming Growth Factor beta 1 (TGF-β1) is a member of the TGF-β superfamily of cytokines. Members of this family exhibit regulatory activity in immunity, proliferation, adhesion, migration, and growth inhibition pathways. TGF-β1 signals through SMAD proteins via the TGF-β RI and TGF-β RII receptors.
Application
PODS are composed of a bioactive cargo protein within a polyhedrin crystal lattice, with polyhedrin as the main protein. The 25 µg SKU size indicates the amount of bioactive cargo, typically 0.5% to 5% of the total protein. For instance, a 25 µg SKU at a 2% cargo loading contains 1.25 mg of total protein. PODS enable sustained release of cargo proteins when proteases degrade the polyhedrin scaffold. Growth factors are not bioavailable until released, and their concentration in media depends on the amount added and the release rate. In 10% serum, peak levels are usually reached within 24-48 hours, with about 20% of the cargo becoming soluble.
PODS often require lower concentrations than conventional growth factors, as they maintain effective levels. Pre-incubating with serum or proteases enhances availability, while conventional factors can be added for immediate effects. Optimal amounts should be determined empirically.

Features and Benefits
- Protein delivery system, PODS human TGF-β1 comes with molecular weight of 36 kDa, length 157 aa and endotoxin level <0.06 EU/ml. PODS co-crystals may be reconstituted at 200 million co-crystals/ml in sterile PBS. 20% glucose has a buoyant density closer to PODS co-crystals and can be useful for aliquoting.
- This product is produced with no animal derived raw products. All processing and handling employs animal free equipment and animal free protocols. PODS co-crystals are highly stable when stored in aqueous solution (pH range 6 - 8).
- PODS provides durability, stability and sustained release, addressing the limitations of conventional and enabling researchers to effortlessly control and manipulate cells in 2D and 3D culture as well as in-vivo.
