PODS™ Human GDNF crystals provide a depot of proteins which are steadily secreted. It has been estimated that the biological activity of 50 million PODS™ 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™ crystals, there are more than 50% of these peak levels still present in the culture system. Ultimately, the amount of PODS™ crystals that is optimal for a particular experiment should be determined empirically, using 50 million PODS™ crystals equivalence to 3.3 µg of standard growth factor is a good 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.

  • Applications:cell culture growth factors
  • Applications:PODS™ protein crystals may be reconstituted at 200 million PODS™/ml in water. 20% glucose has a buoyant density closer to PODS™ protein crystals and can be useful for aliquoting. PODS™ protein crystals are highly stable when stored in aqueous solution (pH

Additional Information:

SOURCE: Spodoptera frugiperda (Sf9) cell culture; LENGTH: 180 aa; STRUCTURE: Dimer; FORMAT: lyophilized; ENDOTOXIN LEVEL: <0.06 EU/ml as measured by gel clot LAL assay; BACKGROUND: Glial cell-derived neurotrophic factor (GDNF) is a neurotrophic factor that signals through a multicomponent receptor system to activate receptor tyrosine kinase RET signaling. GDNF promotes dopamine uptake, prevents motor neuron apoptosis, and supports the survival and differentiation of neurons.
