Description

Electric conversion cup
Technical Field
The utility model relates to a technology in the biomedical equipment field, in particular to an electric conversion cup.
Background
Electrotransformation is a transfection means for introducing foreign substances into cells easily and efficiently, and is a highly versatile and simple protocol for introducing nucleic acids, drug components, and the like into cells. The current research suggests that the electric transformation is the transient stimulation of the cell by an external electric field, which gives enough free energy to the cell membrane, so that the rearrangement of phospholipid molecules of the cell membrane occurs, resulting in the generation of hydrophobic holes on the cell membrane. Molecules of exogenous DNA, RNA, and drugs, etc. mixed in the electrotransformation buffer then enter the cell through the pores of the cell membrane (Neumann E, 1982). The application of transient electric fields during electrotransformation allows a significant change in the pH at both electrodes, increasing cell death (Nordenstrom BE, 1994), while the electric heating produced also increases cell death (Pliquett UF, 2002).
SUMMERY OF THE UTILITY MODEL
The utility model discloses the above-mentioned not enough to prior art exists provides an electricity conversion cup, through increasing the distance between two electrodes, reduces every electrode surface simultaneously and treats the contact width of the cell solution of electric shock to can reduce the death of cell, increase the electricity conversion efficiency of cell.
The utility model discloses a realize through following technical scheme:
the utility model discloses a: conducting strip, electrode, support and electric shock groove, wherein: the conducting strip sets up in support both sides, and the electric shock groove sets up in the support center, and the electrode sets up on the conducting strip and symmetry sets up in electric shock groove both ends.
