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 VEGF-165 comes with molecular weight of 48.8 kDa, length 210 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.
General description
Protein delivery system, Human VEGF-165, PODS contains the polyhedrin protein co-crystalized with Human VEGF-165, a protein that plays a crucial role in angiogenesis, the formation of new blood vessels. Vascular Endothelial Growth Factor A (VEGF-A) is produced by a wide variety of cell types, including tumor and vascular cells. VEGF-A is a mediator of vascular growth, vascular permeability, and plays a role in stimulating vasodilation via nitric oxide-dependent pathways. VEGF-A has several alternatively spliced isoforms, with VEGF-165 being the most abundant. The VEGF-165 isoform is a secreted protein that acts on receptors VEGFR-1 and VEGFR-2 to modulate endothelial cell proliferation and angiogenesis.

The discovery of vascular endothelial-derived growth factor (VEGF) has revolutionized our understanding of vasculogenesis and angiogenesis during development and physiological homeostasis. Over a short span of two decades, our understanding of the molecular mechanisms by which VEGF coordinates neurovascular homeostasis

Metastasis is the leading cause of cancer-associated mortality and the underlying mechanisms of cancer metastasis remain elusive. Both blood and lymphatic vasculatures are essential structures for mediating distal metastasis. The vasculature plays multiple functions, including accelerating tumor growth, sustaining the
