No. The electrical parameters provided by the Nucleofector™ Device are optimized for the cuvettes contained in the Nucleofector™ Kits. The cuvettes are single-use only. Using the cuvettes more than once will result in higher cell death and lower...

No, it seems that the beads bound to the cell surface do not have any influence on Nucleofection™. Larger magnetic beads (i.e. > 1µm) may disturb the Nucleofection™ process and negatively influence cell viability and efficiency.

There are two facts that prove that the DNA is directly transported into the nucleus: 1.) Using the Nucleofector™ Technology, transfection of non-dividing cells is possible. With conventional non-viral transfection methods cell division is a...

The cells which are shown in the HL-60 optimized protocol are living cells and not fixed cells. However a good method for fixation of GFP is to use 3.5%-4% Paraformaldehyde in PBS. Please keep in mind that the fixation method is dependant on what...

No. This vector is only supplied in our Nucleofector™ Kits as a positive control and cannot be used for selection because it does not contain a mammalian selection marker. The only resistance gene expressed by this vector is kanamycin which is only...

We have had good results by incubating the cells in ice cold PBS for 10 minutes and then rinsing the plates. Alternatively, the cells can be detached without a medium change by gently pipetting the cell suspension up and down. Our experience has...

For the preparation of mouse spleen cells we recommend cutting the spleen once and passing the tissue through a 100µM cell strainer or steel mesh using a plunger. The cells are flushed into a petri dish containing PBS. In order to remove fat, cell...

We only recommend the depletion method. For Example, the RosetteSep™ Isolation Kit for human monocytes [Stem Cell Technologies, Cat. No 15028]. The advantage of depletion is that the monocytes are left untouched by antibodies during the process.

The PBS should be calcium and magnesium free to prevent clumping of cells. We routinely use PBS without calcium and magnesium for example Lonza Cat. No. 17-516F
