How do you maintain suspension in cell culture?
Suspension cultures can be maintained in sterile culture flasks (e.g., shaker flasks without baffles) that are not tissue-culture treated; however, spinner flasks (i.e., stirrer bottles) specifically designed for suspension cell culture allow for superior gas exchange and permit higher volumes of cells to be cultured.
What are suspended cell lines?
A cell suspension or suspension culture is a type of cell culture in which single cells or small aggregates of cells are allowed to function and multiply in an agitated growth medium, thus forming a suspension. Suspension cultures are used in addition to adherent cultures.
How long can cells stay in suspension?
3T3 cells do not grow in Methocel suspension culture, while other permanent cell lines do. The viability of 3T3 cells in suspension remains unchanged for at least three days with respect to plating efficiency, vital staining and resumption of normal growth when transferred into monolayer culture.
What is cell suspension technique?
Cell Suspension is a type of bioink in which single cells or aggregates of cells multiply as they lie suspended in a predefined cell media. This bioink has been used in inkjet printers [54], and the cells can be used to aggregate without the need for a scaffold [55,56].
How do you clean suspension cells?
Wash the cells by pipetting 200 μl ice-cold PBS into each well. Remove the PBS from the bottom of the wells by gentle aspiration. Repeat two times for a total of three washings.
How do you do a suspension culture?
Procedure
- View cultures using an inverted phase contrast microscope. Cells growing in exponential growth phase should be bright, round and refractile.
- Take a small sample (100-200μL) of the cells from the cell suspension and count the cells.
- Repeat this every 2-3 days.
What is suspended culture?
Suspended culture involves hanging trays, baskets or nets of young oysters from the surface of the water where they can feed non-stop. The photos show different types of ways oysters can be suspended from the surface.
How many cm2 is a 6 well plate?

What is the purpose of cell suspension?
How do suspension cells grow?
How do you clean suspension cells with PBS?
To wash cells, resuspend the cell pellet in PBS, centrifuge at 350 x g for 5 minutes, and gently pour off supernatant. Resuspend cells in PBS at a density of 107 cells/mL.
