Can I apply more than one program (transfection condition) per plate with the 96-well Shuttle® System?

With the 96-well Shuttle® system, it is possible to apply up to 96 different programs (transfection conditions) per 96-well Nucleocuvette® Plate. Therefore, optimization of Nucleofection® Conditions for a particular cell line can be...

When I transfected my cells, error 8 appeared on the display of the Nucleofector® IIN, IIS or 2b. What is the reason?

Error 8 occurs when there has been an arc within the cuvette during application of the electrical program. The pulse application started but was interrupted because too much current was detected. Efficiency may be lower than expected due to the...

What does the message "weak" mean on the display of the Nucleofector® IIN, IIS or 2b after Nucleofection®?

This message means that the system cut off the pulse before it was completed (usually this is because the conductivity of the solution is at the low end of the normal range). The pulse was applied; it is just going to be a little weaker than...

What cell number do I need per well when using the 96-well Shuttle® Device or the 4D-Nucleocuvette® Stripes?

The cell number is very much dependent on the cell type you use. For high throughput Nucleofection®, we usually start with one fifth of the optimal amount recommended for the standard Nucleofection® in the 100µl cuvette. Currently the absolute...

What is the amount of DNA needed per well when using the 96-well Shuttle® Device?

The amount depends on the cell type and on the DNA construct. As a rule of thumb 400 ng of DNA per well should be applied. However, for some cells or constructs even 100 ng may be sufficient.

Where can I find the meaning of the 4D-Nucleofector® System Error Codes?

In the back of the respective manuals, there is a chart giving a brief description of the error codes. If more information is needed or an error code is recurrent, it is best to contact Scientific Support for advice to determine if there is a...

What is the amount of siRNA needed per Nucleofection® Reaction?

When performing siRNA-mediated knockdown experiments it is advisable to conduct a dose-response (concentration) analysis to determine the minimum siRNA concentration necessary for sufficient target knockdown on the mRNA, protein, or functional level....

Which pipette tips are compatible with the 96-well Shuttle® Nucleocuvette® Plates?

We recommend using special tips, e.g. epT.I.P.S™ (Eppendorf, Hamburg, Germany) or TallTips™ (Matrix Technologies, Hudson, NH, USA). You can contact our Scientific Support Team for a list of compatible tips, including tips for pipetting robots.

According to which standard is the Nucleofector® System certified?

The 4D-Nucleofector® Unit was tested by TÜV Rheinland Product Safety GmbH and found to be in compliance with the following standards:• IEC 61010-1The 4D-Nucleofector® Unit was tested by TÜV Rheinland of North America Inc. and found to be in...

Can I freeze the 96-well Nucleocuvette® Plates?

Yes. Freezing of the plates at -20°C does not alter their properties.
