PODS® Technology

PODS® proteins are made using an insect cell expression system in which the active protein is co-expressed alongside polyhedrin carrier protein. Polyhedrin forms microcrystals within insect cells which specifically capture the active protein to form a co-crystal complex. The active protein is captured in its nascent, natively folded form with limited scope for proteolytic degradation. Consequently, excellent levels of bioactivity are observed. The PODS® co-crystals provide a sustained release mechanism and can be used to functionalize surfaces. For further details, please refer to the PODS® Technology page.

Product Description

The product contains polyhedrin protein co-crystalized with Green Fluorescent Protein (GFP). GFP is a uniquely versatile biomarker and, encased into PODS® crystals, offers a simple way to visualize und localize PODS® crystals embedded in biomaterials, such as hydrogels and scaffolds, using fluorescence microscopy. PODS® GFP crystals can be exited at 488 nm and optimally detected at 510 nm, compatible with commonly available filter sets.

Usage Recommendation

PODS® GFP crystals display the same physical properties as other PODS® growth factor products. While PODS® GFP behave in the same way as other PODS® co-crystals, they differ in that they not contain a cargo protein that elicits effects on cells. Instead of this, they have fluorescent proteins (GFP) embedded. PODS® GFP can be used analogous to PODS® Empty as an inert control, but the primary purpose is to enable visualization and localization of PODS® crystals in cell culture, e.g. in 3D scaffolds, hydrogels and other biomaterials, utilizing fluorescence microscopy.

Reconstitution

PODS® co-crystals may be reconstituted at 200 million co-crystals/ml in water. 20% glucose has a buoyant density closer to PODS® co-crystals and can be useful for aliquoting.

PODS® co-crystals are highly stable when stored in aqueous solution (pH range 6 - 8).

Stability and Storage Upon receipt, store at 4°C. PODS® co-crystals are stable for at least 1 year when dry and 6 months when resuspended.
