There are many kinds of buers and media used for
electroporang cells. Typically, we recommend using media
without serum or anbiocs.
The following is a list of the most commonly used buers and
media:
BTXpress — a single buer soluon, developed to quickly and
eciently deliver genes into mammalian cells that were previously
considered “hard to transfect” by chemical and other non-viral
methods. This soluon, in combinaon with BTX electroporators,
provides researchers with the versality needed for success
across a broad range of cell types while maintaining crical cell
viability. Transfecon using this high performance electroporaon
soluon is equally eecve in delivering DNA as well as siRNA into
mammalian cells.
PBS — a buer soluon commonly used in biological research. It
is a water-based salt soluon containing sodium chloride, sodium
phosphate, and, in some formulaons, potassium chloride and
potassium phosphate. The buer’s phosphate groups help to
maintain a constant pH. The osmolarity and ion concentraons of
the soluon usually match those of the human body (isotonic).
HEPES — widely used in cell culture, largely because it is beer at
maintaining physiological pH despite changes in carbon dioxide
concentraon (produced by cellular respiraon) when compared
to bicarbonate buers, which are also commonly used in cell
culture.
RPMI — a form of medium used in cell culture and ssue culture.
It has tradionally been used for growth of Human lymphoid cells.
This medium contains a great deal of phosphate and is formulated
for use in a 5% carbon dioxide atmosphere.
Op-MEM — an improved Minimal Essenal Medium (MEM)
that allows for a reducon of fetal bovine serum supplementaon
by at least 50% with no change to growth rate or morphology.
Op-MEM can be used with a variety of suspension and adherent
mammalian cells, including Sp2, AE-1, CHO, BHK-21, HEK, and
primary broblasts.
MEM Eagle — suitable for a diverse spectrum of mammalian cell
types. Various formulaons available with either Hank’s or Earle’s
salts.
DMEM —used in a wide range of mammalian cell culture
applicaons. The high glucose version is well suited to high density
suspension culture. The low glucose formula is used for adherent
dependent cells.
CytoMix — a composion of cytokines for the highly ecient
and reproducible expansion of human mulpotent mesenchymal
stromal cells (MSCs).
Water and 10% glycerol — typically used for bacteria
Cytoporaon Media T — a buer designed for larger volume cell
electroporaon as it incorporates a low conducvity of 0.08 s/cm
to reduce heang of soluon during electroporaon.
Cytoporaon Media T4 — a buer designed for larger volume
cell electroporaon as it incorporates a low conducvity of
3.45 ms/cm to reduce heang of soluon during electroporaon.
Electroporation Buffers
