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....

What passage are your B-ALI (Bronchial Air Liquid Interface) cells when plating on transwells?

The cryopreserved epithelial cells, that are screened and guaranteed for differentiation in B-ALI™ (Bronchial Air Liquid Interface) are in P1, the cells plated in transwells are P2. We do not recommend expansion of the cells before...

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.

Can I freeze the 96-well Nucleocuvette® Plates?

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

How many culture/trans-wells does your B-ALI Media Kit kit provide?

1 Ampoule of Normal Human Bronchial Epithelial Cells (NHBE) + 1 B-ALI™ Media Kit will make one 24-well plate for at least 1 month of culture & cells will display beating cilia within 25 days.

Can I integrate the 96-well Shuttle® Device into a liquid handling system?

Yes. The 96-well Shuttle® Device is designed in such a way that it is addressable by robot grippers. Furthermore, the software contains the required interface to be connected with the LHS software. However, the practical implementation for each...

What growth factor is pertinent in chondrogenic differentiation of mesenchymal stem cells?

TGF-B3 has worked best in our hands so that is what we recommend.

Can I use the Nucleofector® 2b Solutions and Optimized Protocols with the 4D-Nucleofector® X-Unit or the 96-well Shuttle® Device?

No. The 4D-Nucleofector and 96-well Shuttle® System uses specifically optimized electrical parameters and solutions. Five different 4D-Nucleofector or 96-well Shuttle® Solutions are available for primary cells. For cell lines, three...

Are there any substitutions that can be used in place of the HSA in the freezing media for hMSC's (Human Mesenchymal Stem Cells)?

Cryopreservation may compromise cell quality and performance. Lonza CANNOT guarantee performance of Clonetics™ & Poietics™ Cells that have been cryopreserved outside of Lonza. To avoid loss of cells and forfeiture of your warranty, we recommend...

Where are Lonzas Small Airway Epithelial cells isolated from?

Lonza’s Small Airway Epithelial cells (both normal and diseased) are isolated from the distal portion of the lung in the 1 mm bronchiole area. These cells are isolated from airway tubules 1mm in diameter and smaller. Anything with a diameter greater...
