Shipping: shipped on blue ice

Storage Conditions: store at -20 °C

Shelf Life: 12 months

Form: lyophilized powder, contains CF3COO- (trifluoro acetate) as counter ion

Solubility: soluble in water

Activity: 3 μl of stock solution is necessary for formation of a non-covalent complex with 1 μg of a nucleoside triphosphate (MW approx. 0.5 kDa carrying 4 negative charges). For different MWs and/or different charges adjust amount of stock solution accordingly.

JBS-Nucleoducin is a mixture of different cell penetrating peptides and proteins, optimized for internalization of nucleoside phosphates into living cells. Some components contain a nuclear localization sequence.
Compared to other CPP or lipid transduction reagents the transduction rate and efficiency are strongly enhanced.
The multi-component composition of JBS-Nucleoducin

  • facilitates efficient complexation with nucleotide cargos
  • is compatible with a large number of cell types and membrane structures
  • triggers different transduction mechanisms
JBS-Nucleoducin shows only marginal cytotoxic effects on a number of cell lines (including HeLa, Jurkat, Swiss 3T3, NIH 3T3, NB-4, and COS-7) and can be therefore, widely used for internalization of nucleotides. For cell survival the critical concentration of JBS-Nucleoducin in serum-free transduction medium is in the range of 10 % stock solution (20 μl in 200 μl) at which cell viability and cell membrane integrity are only marginally reduced (approx. 30 %).

Stock solution:
Dissolve the whole content of the vial in sterile and oxygen free water (CPP-C02S in 250 μl; CPP-C02L in 1.25 ml) according to the general manual. Use the solution immediately or aliquot and store at -20 °C. Please note that the cocktail has proteolytic activity and may form disulfides and S-oxide (Met) when stored in solution. Please also note that the cocktail may form insoluble disulfides (Cys) and S-oxides (Met) when stored in solution. For elimination of potential precipitated material quick-spin stock solution (5.000 - 10.000 g, 5 min) immediately prior use and transfer supernatant into a fresh tube.


Perform calculation, complex formation and cargo transduction according to detailed protocols given in the general manual. JBS-Nucleoducin can be used for transduction of larger amounts.
