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.
The product contains polyhedrin protein co-crystalized with mCherry. mCherry 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® mCherry crystals can be excited at 587 nm and optimally detected at 610 nm, compatible with commonly available filter sets.
PODS® mCherry crystals display the same physical properties as other PODS® growth factor products. While PODS® mCherry behave in the same way as other PODS® co-crystals, they differ in that they do not contain a cargo protein that elicits effects on cells. Instead of this, they have fluorescent proteins (mCherry) embedded. PODS® mCherry 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.
This product is produced with no animal derived raw products. All processing and handling employs animal free equipment and animal free protocols.

PODS® were lyophilized from a volatile solution
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.
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.
