PODS® Empty, 25 mg

PODS® Empty crystals are composed solely of polyhedrin protein. As these PODS® do not contain any cargo protein, they are sold by weight of the polyhedrin protein, rather than cargo weight.  This product is intended to be used as a negative control alongside cargo-containing PODS® co-crystals. The cross-reactivity of PODS® Empty crystals has been tested on a variety of cells including mouse ES cells, PC12, fibroblasts, and ETS embryos, and there was no observable interference with the tested cells. Additionally, in-vivo data indicate no inflammatory response to PODS® Empty crystals in animals.

• Length:  250 aa
• Molecular Weight:  28.7 kDa
• Structure:  n/a
• Source:  Spodoptera frugiperda (Sf9) cell culture
• Accession Number:  D37771.1
• Formulation:  PODS® were lyophilized from a volatile solution
• Reconstitution:  Ensure the PODS® are resuspended in buffer by pipetting up and down immediately before aliquoting. PODS® may be reconstituted at 100 ug/ml in water. 20% glucose has a buoyant density closer to PODS® and can be useful for slowing sedimentation when aliquoting. PODS® are highly stable when stored in aqueous solution (pH range 6 - 8).
• Stability and Storage:  Upon receipt, store at 4oC. PODS® co-crystals are stable for at least 1 year when dry and 6 months when resuspended.
