- Obtained cells are compatible with downstream applications
- Mild, non-toxic, biodegradable
Kit Includes
- 1 box of LarSep Columns (25/pk)
- 1 LSC Separator (single channel)
- 1 Separation Stand
Work Flow
- Antibody incubation: Incubate the antibody with cell suspension at 4ºC for 10-15 mins.
- Microbead incubation: Incubate the magnetic microbeads with cell suspension at 4ºC for 10-15 mins.
- Magnetic separation: Put the separation column into the magnetic field and add the cell suspension into the column.
- Only cells labeled with magnetic beads will be captured in the column.
- Elution: Remove the column from the magnetic field and add a buffer to elute the positive cells.
