PODS® Human IL-10
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 the polyhedrin protein co-crystalized with Human IL-10. Interleukin-10 (IL-10) is an anti-inflammatory cytokine produced by macrophages and type 2 T helper (Th2) cells. IL-10 inhibits the production of pro-inflammatory cytokines such as interferon-gamma (IFN-gamma), Tumor Necrosis Factor alpha (TNF-alpha), interleukin-2 (IL-2), interleukin-3 (IL-3), interleukin-4 (IL-4), and Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF), made by macrophages and regulatory T cells. IL-10 also suppresses antigen presentation on antigen presenting cells, and enhances the survival, proliferation, and antibody production of B cells. Human IL-10 can act on mouse cells, while mouse IL-10 is not active on human cells.
PODS® co-crystals provide a depot of proteins which are steadily secreted. It has been estimated that the biological activity of 50 million PODS® co-crystals generates the same peak dose as 3.3 µg of standard recombinant protein. However, at 5 days following the start of seeding the PODS® co-crystals, there are more than 50% of these peak levels still present in the culture system. Ultimately, the amount of PODS® co-crystals that is optimal for a particular experiment should be determined empirically. Based on previous data, we suggest using 50 million PODS® co-crystals in place of 3.3 µg of standard growth factor as a starting point."
To control for cross-reactivity with cells or as a negative control, we recommend using PODS® growth factors alongside PODS® Empty crystals, as the latter do not contain or release cargo protein.

Research Use Only
This product is for research use only.
|Spodoptera frugiperda (Sf9) cell culture
|<0.06 EU/ml as measured by gel clot LAL assay
|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.
