How long is the MycoAlert® Mycoplasma Detection Assay signal stable?

Please follow the protocol exactly as written – add reagent, wait 5 min and read, add substrate, wait 10 minutes and read again.

When nucleofecting cancer cell lines, do I need to be concerned about passage number?

For the most efficient gene transfer, we recommend using cells that are in logarithmic growth phase and at a passage number of 10-15 (from the time of thaw). This is because some cell lines differentiate and change their features after many passages.

What antibiotic concentration should I use for selecting stable transfectants?

We highly recommend to perform a titration for G418 in a range of 0,1 mg/ml to 1,5 mg/ml; in serum-free culture expand range down to 20 µg/ml).Choose the concentration which is 0,1 or 0,2 mg/ml above the one which shows complete cell death...

Do you have any tips for the culture of primary cells or cell line prior to Nucleofection?

Yes. Please see our Techincal Reference Guide which contains many helpful tips.You can find additional information in the Optimized Nucleofection Protocol for your cell type of interest.

At which time point after Nucleofection® should I start selection of stable integration?

Antibiotics for selection should be added 24-48 h after Nucleofection®.
Missing: cell lines

How often should I change the medium during selection of stable clones after Nucleofection®?

The culture medium should be changed every 2-3 days during the selection process.This eliminates potentially toxic substances produced by dying cells and secondly, it keeps the concentration of the antibiotic at a constant level.

What are the critical steps for successful Nucleofection® of monocytic cell lines like THP-1, HL60 and U-937?

To achieve optimal results, we strongly recommend following the Optimized Protocols in regard to cell culture conditions (medium, splitting cycle, density before Nucleofection), DNA amount and purity.Please also be sure not to exceed 90xg when...

Can I optimize the transfection efficiency or cell viability after the 4D-Nucleofector® Cell Line Optimization any further?

We offer a program fine tuning matrix for Optimization of Nucleofection® Conditions - A Short Guideline (lonza.com)Based on your current most satisfactory pulse(s) it provides guidelines which further programs to test to either increase cell...

What should I pay attention to when transferring my reporter gene set up from a cell line to a primary cell?

In general the overall expression level differs between different cell types. Don't expect the same level of gene induction when working with primary cells. You might need to change to other DNA amounts or ratios.

I am using the acute leukemia HL-60 cell line for CAR-T cells experiments. Do you have a transfection protocol for genome editing?

The HL-60 cells are often used as a model for in vitro research for treatment of AML (acute myeloid leukemia) in combination with modified primary human CAR- T cells (T cells expressing chimeric antigen receptors).Transfection protocols can be found...
